Michelangelo commonly referred to his nickname Mikey is one of the main protagonists in the 2012-2017 TMNT television series. The youngest adoptive son of Master Splinter/Hamato Yoshi and youngest adoptive brother of Karai/Hamato Miwa, as well as the youngest birth brother of Leonardo, Raphael and Donatello, Mikey is known as the the "wild one" of the team and is a lover of games, skateboarding, pranks and pizza. Though he possesses a "child-like" free-spirited and carefree innocence, he always brings his A-game in a serious brawl. His character design was updated as well, making him slightly shorter than his brothers and giving him dark freckles as well as shorter tails on his mask.
Unlike past incarnations, Mikey does not say his famous "Cowabunga" catchphrase, although in Season 3 he says it , but instead he mainly says "BOO-YA-KA-SHA!" He usually does this when accomplishing something or attacking an enemy. In the episode "Meet Mondo Gecko" the character Jason (a.k.a. Mondo Gecko) uses 'cowabunga' as his own catchphrase, and Michelangelo says it's "too old school" but later asks if he can use it from time to time. Starting with the episode "Journey to the Center of Mikey's Mind", he says "Booyakabunga" (a mixture of both Booyakasha and Cowabunga).
He wears an orange mask and fights with two nunchaku, which convert into kusarigama ia a blade inside of one of the sticks of each nunchaku and extra lengths of chain stored in the other. This version of Mikey is voiced by Greg Cipes.
Mikey is a light green Mutant ninja turtle. Unlike all of his previous incarnations, Mikey has freckles. Like all in incarnations, however, he wears an orange mask, though like his 1987 and 2003 incarnations, the tails of his mask are shorter. Mikey is shorter than his brothers and is considerably shorter than Donatello. Mikey also seems to be a little more pudgy than his brothers. The animators gave Mikey baby blue eyes to make him look slightly more 'innocent'. However, like all of the Turtles when they're in combat, the pupils and irises vanish from his eyes, leaving him with empty, white eyes, which are similar to that of the 2003 incarnations.
Michelangelo is the youngest, shortest, and least mature of his turtle brothers; however, it was confirmed that his maturity slowly increases as the episodes go on. He is labeled as "The Wild One" and "The Party Dude" as he is the most "fun" out of all the turtles. He is also very social, and wants the outside world (humans) to accept him and his brothers. He is also impulsive, because of a severe case of ADD. He is the first of the turtles to taste pizza and is very proud of his talent for naming things. In battle his weapon of choice is a pair of nunchakus, and a kusarigama. He might seem unintelligent due to his apparent disregard for thinking things through, but he is actually quite clever. Unfortunately he also isn't always the most considerate of the ninja turtles like when he tried to use Raph's fear of Cockroach Terminator to get Raph to let him read his comics, or when he pranks his brothers. But he also has an honest heart and is more willing than the other turtles to accept outsiders like Karai/Miwa and Leatherhead.
Enthusiastic, impulsive, silly, creative, social, positive and adaptable, Michelangelo is extremely creative and goes with the flow. He loves to joke around and pull pranks, especially with his brothers. He loves pop culture and readily accepts opportunities to widen his social group. As a brother and friend, Michelangelo is always openly playful and affectionate. While not very bright or book-smart, he can surprise others with his intuition, his keen sense of heart, and his quick reflexes even in the absence of conscious thought.
Mikey is the youngest brother and is prone to goofing off rather than focusing on his training. However, he is still an impressive fighter. His natural affinity for the martial arts is present with his ability to learn moves after seeing it only a few times. He also has the ability to fight without "thinking", once deflecting Splinter's blows while listening to music with his eyes closed, which was something that Donatello had to learn (Although he was unable to do this when directly asked to fight without thinking in their first fight with the telepathic Victor Falco).
Although Mikey isn't the brightest and has a tendency to make mistakes, it's very clear that all of his brothers care very deeply for him. They all show great distress when he gets hurt or is in trouble, and anger at the one who threatens him, i.e. when Baxter Stockman is throwing Mikey around he is in his more advanced armor. More often than not, Raphael is the one to shout Mikey's name first and attack whoever has harmed his little brother, and was distraught when Mikey was injured during his (Raphael's) brief period as leader of the team.
Master Splinter has yet to reveal what it is Michelangelo must improve on, other than a need to focus. In the First Nickelodeon TMNT Comic Master Splinter states that Mikey has more raw talent than his three brothers combined. Later in an episode, he says that Mikey has his "challenges" too. And even if Mikey can give his brothers grief, they will always care and love him and have his back. It is heavily implied that this version of Michelangelo has some form of ADHD.
Michelangelo has the tendency to be scatter-brained, naïve and excitable, which sometimes causes trouble for the team. However, his brothers are defensive of him on occasion, especially his second oldest brother, Raphael. Though they find his idiocy rather irritating, they often freak out when he shows intelligence. Michelangelo sets a trend early in Season 1 of giving designated names to various mutated enemies, getting very upset if someone else names them before he can. This is evident when he finds out that Donatello named The Newtralizer.
Fifteen years before Rise of the Turtles, Part 1, the benevolent Hamato Yoshi purchased the four turtles as pets. Yoshi came into contact with a rat and had to fight against a couple of Kraang. During the scuffle, the aliens dropped a container of mutagen, causing the mutation of Yoshi and the turtles. Yoshi raised the turtles as his own children and to train them in Ninjutsu.
Michelangelo and his brothers were once ordinary turtles; when they were infants, they were adopted from a pet store by Hamato Yoshi. When their soon-to-be father walked passed a strange man, a kraangdroid, he felt something odd about him and followed. Unfortunately Yoshi gave away his position when he accidentally stepped on a brown rat's tail. The Kraang found him and attempted to kill him, but Yoshi fought back hard. In the end, the Kraang dropped the canister of Mutagen they were holding, causing the turtles and Yoshi to mutate. Yoshi, having to have stepped on that rat, thus mutated into a humanoid brown rat by the name of "Splinter", While Mikey and his brothers, after coming in contact with Splinter when he was human, mutated into humanoid turtles.
Splinter knew they would never be accepted in society, so he took them to the sewers, made a home down there, and made the four turtles his children. Knowing the world would be dangerous and there would be a time where they want to explore the outside world, Splinter trained the boys in the art of Ninjitsu. Mikey and his brothers were named after great Renaissance artists from a book Splinter fished out of the storm drain.
Skills, Powers and Abilities
Michelangelo is considered the most acrobatic and talented of his brothers. His nunchakus match his flexible abilities when it comes to battle. While he's not as disciplined as Leonardo, rebellious as Raphael, or as smart like Donatello, Mikey's raw talent, agility and sheer unpredictability make up for it.
- Potential: Splinter considers Michelangelo the one with the most potential of all of his three brothers combined, particularly complimenting his ability to fight without thinking (Although he cannot do this when actually asked to do so, panicking when Donatello asked him to confront the telepathic Dr. Victor Falco). His potential also translates to his intelligence. This is show whenever he is in Dimension X. There, Mikey is shown to known how the dimension works, what its creature's are, and how to handle Kraang technology in the dimension.
- Ninjutsu: Mikey is the most agile of all his brothers; his training as a ninja helped to balance and improve this, but his skills in skateboarding and dancing also gives Mikey an edge that will often shock his brothers. Mikey is an extremely good fighter. He's got a great knowledge with ninjutsu, which is why he is a good fighter. He may have the most raw talent of the four, but he does not seem to have the skill or the inclination to develop it.
- Pranks: He refers to himself as the king of pranks. Since he the most funniest of his brothers and he hasn't shown to be wrong since he was able to show his pranking skills against his brothers like water balloons as he wants to prank them all and he was able to use his prank of water ballon to use against the tank of the truck.
- Teaching: He has shown Napoleon the right way of Ninjutsu correctly as he was shown great success as he may not be the great Ninja turtle for thinking of correctly of logic from his brothers but he proven to teach others to fight well.
- Cooking Skills: He shows to love to cook for his family even though his brothers don't think his tastes great but to Mikey it does. Leatherhead seems to love his cooking skills. (Probably because he has never eaten anything delicious) In Mikey Gets Shellacne, it is revealed that he's usually the one who makes breakfast and that the others are a real hazard in the kitchen when they have to do so. Revealing that Mikey DOES know what the others like and how to give that to them.
- Shadow Puppet Skills: He able to make different shadows out of his hands very well to be appear realistic of different objects. He used this to deceive the Kraang, Fishface, and Rahzar.
- Balance: Mikey's skills as a skateboarder and a ninja give him a great ability with balance.
- Intelligence and Communication : He not the smartest of like his brothers are but he makes it up for knowing comics and naming creatures. As he shown to be excellent naming creatures if their appearance, abilities or powers. Just like any other creature mutated of humanoids able to speak. He also use his comic intelligence to defeat the mutation Squirrels and true genius in Dimension X. He is typically smarter than his brothers believe him to be, for he is capable of creating antidotes and retro-mutagen from random ingredients, though his brothers continue to doubt his intelligence for obvious reasons for example when Mikey sprinkled botched retro-mutagen onto his skin when Donnie had clearly labelled it as being dangerous.
- Creativity: Michelangelo has to be quite creative both in and out of combat. This mostly when he comes up with the names for most of the villains that they fight in the series.
- Emotional Intuition: As shown in Buried Secrets and Clash of the Mutanimals, Mikey has a strong intuitive sense for when other people are "off".
- Okinawan Kobudō (Nunchaku): Michelangelo was trained by Splinter in the art of the nunchaku. Aside from using them to wrap around an opponent's joints and weapons to disarm, Mikey swings and strikes with them in the manner akin to flails. Given Mikey's unpredictable nature, his able to make extensive use of his nunchucks in rather uncommon but effective ways in a fight as well as mix his attacks with the capoeira fighting style.
- Kusarigamajutsu: Mikey's ability with the nunchaku also translates to his use of the kusarigama. His nunchucks both posses a retractable blade at the end them and can also extend in chain length. With it, Michelangelo possesses an even greater range of attack than with his regular nunchucks, able to swing it overhead and strike with the bladed end, or entangle his enemies with chain and swing them around.
- Kama Proficiency: In Vision Quest, when the Turtles were preparing to venture into the spirit plane, Mikey forged himself a pair of kama to use in battle.
- Tonfa Proficiency: While traveling in space to fight the Triceritons, the Fugitoid invented a pair of laser tonfa for Michelangelo to fight with.
- Kyūjutsu: Michelangelo also possesses aptitude in archery and uses a yumi and arrow to fight long-ranged.
- Shurikenjutsu: Michelangelo can throw shiruken with remarkable accuracy.
- Enhanced Strength: He was able to throw barrels over his head at Spider Bytez. He was also strong enough to kick back Rahzar during the fight at the Auman Chemicals factory. Mikey was also strong enough to lift a mailbox from the sidewalk and throw it at Traag. His ninja training with Master Splinter has helped to improve and condition his strength.
- Enhanced Speed: Michelangelo is able to move at great speed, able to free run on rooftops without losing momentum. He also possesses great reaction speed, allowing him to dodge projectiles such as lasers the Kraang's blasters, and enemy attacks. He can also spin his nunchaku at incredible speed to add momentum to his strikes. He can run much faster than an athletic human.
- Stealth: Being taught by Splinter, Michelangelo, as well as his brothers, are able to be one with darkness and hide and move within the shadows without being noticed. Mikey has the ability to move in the shadows, like his brothers. He is also very stealthy, but does not enjoy when stealth is used on him.
During most of the series, Michelangelo wields a pair of nunchaku with which, like his brothers with their chosen weapons, he is highly skilled. In fact, he uses both a kusarigama and nunchucks. In some episodes he refers to them as 'chucks'—such as in The Kraang Conspiracy he says "Okay, that was just gross, dudes. I have April Derp on my chucks." (April Derp had been reduced to black goo at this point).
In The Pulverizer Returns!, Splinter says that the boys are getting too reliant on their own weapons and makes them swap. After this process, Michelangelo is left with Leonardo's Katanas (which leads him to do an impersonation of his brother and make him believe he is the leader by virtue of having the swords). During a fight, the Turtles become uncooperative with their new weapons and swap back. When Splinter finds out, he takes away all of their weapons, stating that any object can be useful for real ninjas. When he and his brothers are trying to save Timothy, Michelangelo uses a chain and holds and fights with it in a style similar to his Nunchucks. Both of his nunchucks can convert into kusarigama. In Turtle Temper and The Gauntlet he also used a Yumi bow and like the rest of his brothers wields shuriken. In Target: April O'Neil, he briefly used a Kraang blaster that he picked up, and a plasma sword he stole from Chrome Dome, both of which he dropped after he almost hits his own brothers.
During his time in space throughout the first half of Season 4, Michelangelo used laser tonfas and a laser blaster created by Fugitoid as his main weapons. Throughout the remainder of Season 4, and throughout the fifth and final season, he continues using his regular nunchaku. In the 4-episode Monsters vs. Mutants story arc, Mikey is given an arm-mounted stake-shooting crossbow as part of his monster-hunting attire.
Mikey seems to respect Leonardo and although there are few scenes with them interacting together in the first two seasons, it's clear that Leonardo cares about his youngest brother. In season three, however, the two of them go on missions together. While looking for Karai one evening, they worked together to rescue their brothers, April, and Casey from Bebop and Rocksteady. After Karai is captured by Shredder, Leo volunteers to go solo to find a way to help her, Mikey tags alongside him and assures he is there for him. When Mikey gets eaten by the MegaShredder, Leo fights with all of his might to save him. After Mikey escapes from inside the monster, Leo is overjoyed to see him alive and is proud of the work they have done.
Raphael is normally seen as the one Mikey loves to hang out with, usually to Raph's ire. Although Raph repeatedly gives Mikey a beat down for his antics (usually in the form of slapping him to make him shut up) he occasionally shows a more sensitive side when Mikey is feeling down. Particularly at the end of season 2 and the first half of season 3, Raphael is much kinder to Michelangelo and often refers to him affectionately as "little brother". He is also less inclined to slap Mikey, instead flicking him with a finger as a sort of "warning".
Of all his brothers, Mikey seems to be the closest to Donatello. This probably stems from the fact that although they are very different they both share a curiosity about things outside ninjutsu. Mikey greatly admires Donnie's new gadgets and is normally the first to test them out,. Mikey additionally enjoys creating names for all the mutated forms of villains in the series, naming ones like "Dogpound" and "Fishface". He even is upset with Donnie when he decides a name (Newtralizer) before Mikey gets the chance, and Donatello yells at Mikey when he attempts to name the mutated Kirby O'Neil "Wingnut" - "You are NOT giving Mr. O'Neil a MONSTER NAME!"
- Leonardo - Michelangelo's oldest brother. He and Leonardo are the only ones that don't seem to fight that much with each other, but Leo sometimes criticizes his excitable behavior. Mikey also tends to imitate Leonardo as a leader in a funny way. Michelangelo doesn't seem to interact with Leonardo as much as he does with his other brothers Raphael and Donatello. In season three, however, he does go on two missions with Leonardo. In one of them, they save their brothers and human friends from Bebop and Rocksteady. While in the other, they try to get a brain worm to save Karai and before they go Mikey assures Leo that he's always there for him.
- Raphael - Michelangelo's second-oldest brother. He gets beaten up by Raph in a playful manner (sometimes violently) which is almost always punishment for Mikey's stupid or irrelevant comments. Raph is very protective when it comes to Mikey, such as facing his fear when a giant cockroach took Mikey in Cockroach Terminator or in I, Monster, when Splinter hurts Mikey, Raph immediately becomes angry. It is also shown that Mikey cares for Raph. In The Gauntlet, when Shredder electrically shocked Raph, Mikey was the one who ran to him to make sure he was okay, and in The Pulverizer he's the one who stays at Raph's side when he gets poisoned, and takes care of him. In Slash and Destroy, when Slash beats up Mikey, Raph was deeply shocked by this and stopped Slash.
- Donatello - Michelangelo's third-oldest brother. He seems to fight with Donnie the most because of their completely opposite personalities, but they do tend to get along while they're fighting the Kraang and the Foot. Also, they seem to be really close as brothers. It is also shown that Donnie is very protective of him and does things such as yelling Mikey's name when he gets hurt, or stopping Dogpound from killing him. (Nickname: "B-Team") He is closest to Donnie and they interact the most.
- Hamato Yoshi / Splinter - Michelangelo's adoptive father. He usually doesn't understand his sensei's advice very well, and doesn't really take it that seriously, but he trains well under Splinter, despite his slight dimwittedness. Out of all the Turtles, Mikey interacts with Splinter the least. However, when it comes to his safety and that of his other brothers, Splinter always gets concerned.
- Hamato Miwa / Karai- As she spends most of her time personally messing with Leonardo or taking on all comers at once, Karai has limited interaction with Mikey. However, when Mikey learned of her familial relationship to Splinter, he incredulously queried, "She's our sister!?" As shown in The Pig and The Rhino and Serpent Hunt, Mikey has completely accepted Karai as his sister, and is one of the most visibly affected when Karai says a final good-bye to the turtles.
- Ice Cream Kitty - When April found a stray cat and left her for Michelangelo to look after, the stray cat ate some ice cream laced with the mutagen that mutated her into Ice Cream Kitty. At first, Mikey was horrified about what would happen if April discovered what happened to the cat. But later, Mikey brought Ice Cream Kitty to battle against the Rat King. Since then, Mikey decided to keep Ice Cream Kitty as his pet.
Friends / Allies
- April O'Neil - Michelangelo's first human friend. He and April do not seem to interact much, but they care about each other as friends. In Buried Secrets, a rift temporarily formed between Mikey and April after Mikey suspected and attacked the woman claiming to be April's mother; but Mikey was later proven right, April's "mother" had to be destroyed, and Mikey and April's relationship mended. Later, Mikey told April that he and his brothers are her family. In The Croaking, after Mikey's brothers and Casey are angry with him for making a mess in the O'Neil Farmhouse living room and he ran away from home instead of cleaning it up, April was shown to be defensive of Mikey and sensitive of how the others sometimes mistreat him.
- Casey Jones - A friend and ally, but the two were seldom shown interacting in any more meaningful way until Meet Mondo Gecko, when they bonded over a strong shared interest in skateboarding.
- Leatherhead - One of Michelangelo's first mutant friends, the two hit it off very quickly and came to share a loving bromance. Mikey was the first person since mutation ever to show Leatherhead compassion, and the two developed a strong mutual affinity and rapport. Mikey has proven to be one of the few influences that could calm Leatherhead down from his fits of rage and make him feel at ease. Indeed, they became extraordinarily affectionate and intimate, with Mikey giving Leatherhead massages and body rubs in attempts to calm him down when angry and even sleeping spooned together on the Living Room floor. In TCRI, when the Turtles saw Leatherhead again for the first time in the episode, Mikey immediately reacted with love at the sight of Leatherhead sleeping. Later in this episode, Leatherhead became stranded in Dimension X, and the two would not meet again for an entire season. Later in Into Dimension X! after the long-imprisoned Leatherhead managed to send a message through a portal to the turtles, Mikey was shown to strongly care and miss Leatherhead in a series of tender sepia-toned flashback scenes, and he impulsively leapt into Dimension X to rescue him. This reunion was short-lived, as Leatherhead soon went missing again during The Invasion, Part 2 and neither he nor Splinter joined the others who fled to the O'Neil Farm. Mikey and Leatherhead met again in Battle for New York, Part 1 and Part 2, with their mutual affection undiminished as they shared tender caring embraces in three separate scenes over course of the two-part episode's events. Leatherhead is one of the few people to consistently call Mikey by his full five-syllable name "Michelangelo," rather than just "Mikey."
- Timothy / The Pulverizer / Mutagen Man - Michelangelo acts positively towards Timothy, but seldom interacts with him, and sometimes forgets he even exists. In The Pulverizer Returns!, Mikey saw the newly Foot-recruited Timothy from afar and commented, "Anybody else find this dude kind of adorable?" Later in that episode, when Timothy sent a text message to Donatello, Donnie said, "Text message from you-know-who." But Mikey had forgotten all about Timothy, and Donnie corrected, "Text message from everybody-but-Mikey-knows-who." When Timothy later turned against the turtles and started drinking mutagen, it was Mikey who named him "Mutagen Man."
- Napoleon Bonafrog - The second of Michelangelo's mutant friends, though Napoleon attacked him in their first meeting, they seem to connect with each other throughout their time together even teaching other their respective skill. Napoleon also chose to free Michelangelo rather than fight his brothers and friends even successfully using a Ninjutsu move that the turtle taught him.
- Jason / Mondo Gecko - In Meet Mondo Gecko, when Michelangelo and Casey Jones went out to get some action, they encountered another reptilian mutant, who Mikey nicknamed "Mondo Gecko." What Mikey didn't know is that Mondo worked for Fishface and had him and Casey captured. Feeling bad for what happened, Mondo tried to liberate Mikey and Casey, but all three of them end up competing against Fishface in his deadly game. Using team work, Mikey, Casey and Mondo competed in the race and defeated Fishface, freeing Mondo from Fishface's exploitation. What really fascinated Mikey about Mondo are having to touch his eyes with his tongue and his "old-school" catchphrase, "Cowabunga!"
- Shinigami - She is Karai's friend with whom he was smitten with the moment they met.
- Renet - In the events of "Turtles in Time", Mikey began to develop a crush on Renet, the time travel mistress apprentice. While the others tend to dislike Renet from bringing them to the Middle Ages and being a bit clumsy, Mikey instead admires Renet for her appearance and her cool fighting style. Mikey even referenced having a date to riding a Middle Age horse together. It is even seen that Mikey cares for Renet, as he was chasing after her during the final battle with Savanti. In fact, (unlike Donnie) Mikey gets his first kiss from Renet at the end of the episode when he asks her out. Renet in reply smiles, saying it would be nice to do that next time and proceeds to kiss him on the cheek.
- Oroku Saki / The Shredder - Michelangelo's arch nemesis. Mikey first met Shredder in The Gauntlet and was terrified at first, but he still managed to escape with his life, along with his brothers. He seems to be intimidated and scared by him.
- The Kraang - Michelangelo's targeted archenemy. Mikey was the first of his brothers to discover these aliens with robot bodies and is freaked out by the brain/squid like creatures inside of them. Not much interaction is shown, but it is obvious that he dislikes them.
- Baxter Stockman - One of Michelangelo's enemies. Mikey accidentally gave Baxter Stockman the T-pod, which upgraded his armor and made him a more competent villain. He defeated Baxter by shoving bees in his face, further heating Baxter's dislike of the turtles. Although further interaction is unknown, he is shown to dislike him. He dubbed him The StockmanPod after Baxter upgraded his armor.
- Xever Montes / Fishface / Mr. X - One of Michelangelo's enemies. Mikey dubs him Fishface after Xever mutates into a fish. Mikey later helps free his new friend Mondo Gecko from Xever's exploitation.
- Chris Bradford / Dogpound / Rahzar - One of Michelangelo's archenemies, though his mixed treatment of Bradford has proven more complicated than that of clear-cut enemy. When Bradford was still human and a public martial arts celebrity, Mikey deeply admired and fanboy-ed over Bradford, wanting to become his friend. They eventually accepted each other's friend requests on Face range (a fictionalized version of the website Facebook). Bradford was actually very much not Mikey's friend, but he managed to trick Mikey into thinking they were friends so that Bradford could extract information and use Mikey as bait to help his secret master Shredder get to Mikey's Master Splinter. During their time of false friendship, Mikey nicknamed Bradford "Rad Brad", and Bradford taught Mikey his signature kata, the Death Dragon, which Mikey later demonstrated it to his brothers in the Dojo. But when Splinter witnessed Mikey perform this move, he instantly recognized it as a Foot Clan maneuver that Oroku Saki had used against him in the past when he was still human. When Mikey had outlived his usefulness, Bradford declared he was never Mikey's friend to begin with, and was actually sworn enemy to Mikey, his brothers and his Master Splinter, and that he was a disciple of the Shredder. This revelation deeply hurt Mikey's feelings, ended all pretense of friendship, and all but killed his affection towards Bradford. Later, Bradford mutated into a dog-like creature which Mikey dubbed "Dogpound". Mikey called him "Rad Brad" one more time even after this mutation. Even later still, Dogpound mutated again into a werewolf-like form, which Mikey dubbed "Rahzar". Mikey's Bedroom had a life-size cardboard cutout of human Chris Bradford, which Mikey never got rid of even after they had cemented their mutual enmity, and was still standing in his room when they finally had to abandon the Turtle Lair. In Vision Quest it was shown that Mikey's spirit enemy is Rahzar with after a struggling battle Mikey defeated him in the spirit plane.
- Snakeweed - Another of Michelangelo's enemies. He was the first enemy of the turtles whom Michelangelo nicknamed.
- Dr. Victor Falco / The Rat King - He is the first mutant enemy of the turtles who wasn't named by Michelangelo.
- Vic / Spider Bytez - He is the second mutant enemy of the turtles whom Michelangelo named.
- Michelangelo is named from the famous Renaissance master, Michelangelo di Lodovico Buonarroti Simoni.
- Michelangelo's name is Italian, from Hebrew and Greek derivation. The component Michel- is from Hebrew מִיכָאֵל, (Mīkhāʼĕl), meaning the question "Who is like God?". The -angelo component is from Greek ἄγγελος (ángelos), meaning "angel; messenger." The name originally referred to the Archangel Michael.
- In Katakana, Michelangelo's name is spelt: ミケランジェロ (Mikeranjero).
- Given the fact that he was adopted by Hamato Yoshi/Splinter, Michelangelo's full name could be `"Hamato Michelangelo," or in Western naming order, "Michelangelo Hamato."
- Michelangelo also has an affinity for animals in this incarnation, as well as a fear of squirrels. Whilst he is more interested in comics and cartoon shows (such as Crognard the Barbarian and Super Robo Mecha Force Five) than animals, he adopted a cat April found on the street after the cat ate some mutagen Mikey had spilled ice cream in, resulting in the arable and delicious Ice Cream Kitty; most likely this incarnation's version of Klunk. Michelangelo's relationship with Ice Cream Kitty parallels Raphael's with pre-mutation Spike, wherein he will tell Ice Cream Kitty his innermost feelings and fears, and not feel judged by them - as often his brothers find Mikey's concerns and thoughts too silly to be worth their time. Bearing this in mind, however, Michelangelo does not seem to have any special relationships with animals like he has done in other incarnations, though he still cares for animals deeply, as exhibited by his caring for April's chickens whilst the Turtles are at April's old farmhouse at the start of season 3
- While Michelangelo still fights with his weapons of choice, a pair of nunchaku, in this incarnation they can both be converted into kusarigama, (a "chain-sickle"), via a retractable blade inside of one of the sticks of each nunchaku, and extra lengths of chain stored in the other stick of each nunchaku.
- This new feature actually makes its first appearance in Rise of the Turtles, Part 1, when Michelangelo takes on a lone Kraang and in fear uses the blade of the kusarigama inside one of his nunchaku, slicing open its face, revealing it to be a robot, (the actual first appearance of Mikey's kusarigama is shown in extended version of this episode during a change-screen, where the Turtles are ready to go up on their first excursion to the surface, as all four turtles are shown with their weapons, Mikey's nunchaku are shown becoming kusarigama.
- His mastery of Ninjutsu includes: Taijutsu, Qigong, Nunchakujustu, Kusarigumajustu, Shurikenjustu, Archery, Throwing water balloons, Hensojustu, Sui-ren, Intonjustu, Kayakujustu, Naming stuff, and Pranking anyone.
- He is the shortest one of the group, about under 5 ft tall as well as the youngest of his brothers.
- In the Russian dub, Michelangelo's nickname, Mikey, is pronounced "Мickey".
- In this incarnation, Michelangelo is the one who primarily does the cooking, even after discovering pizza. He cooks well enough that his brothers prefer him to make breakfast, but he does not usually cook so well that his brothers are fond of what he makes, usually because he uses unpalatable combinations of ingredients. Leatherhead is most fond of Mikey's cooking.
- But in "Pizza Face", it was shown that Michelangelo also makes homemade pizzas. He even makes his own pizza crust from scratch, which in real life is typically the most complicated and time-consuming part of making pizza.
- He is the one who gives the names to the people that have been contaminated with mutagen, but also other things like the T-pod. He also gets somewhat irritated when someone else does the naming of new items and bad guys.
- In Eyes of the Chimera, it is implied that MIkey holds some knowledge about myths, as seen when he stated that there's a name for the mutant they were facing, to which Donatello asked if he meant Chimera, to which Mikey corrected him, claiming it is actually Turduken.
- Michelangelo and Beast Boy (from Cartoon Network's Teen Titans and Teen Titans Go!) seem to be similar; same voice actors, they like pizza (more accurately they both like junk food, comic books and video games, they like to make jokes, listening to music and goofing around, and they both even have the same skin tone (which is green), and they are both the closest to the smart one of the group (Michelangelo & Donatello and Beast Boy & Cyborg). Interestingly, Michelangelo and the other Turtles would later be featured in the Teen Titans Go! episode, "Truth, Justice and What?".
- He is shown to hate Polka music, as shown in "I Think His Name is Baxter Stockman".
- His catchphrase in this incarnation is "Booyakasha!" (which is an equivalent of the Turtles' famous "Cowabunga!"), though Mikey has said "Cowabunga!" and "Booyakabunga!" (an amalgamation of "Booyakasha!" and "Cowabunga!") in the series as well.
- His catch-phrase was changed from "Cowabunga!" to "Booyakasha!". When Karai amusingly and incredulously asks what it means, Mikey responds saying that he has no idea, it's just really fun to yell.
- Mikey shouts "Cowbunga!" for the first time in "Meet Mondo Gecko".
- His favorite comic is about two characters called Wingnut and Screwloose which are based on Batman and Robin respectively
- Michelangelo seems to develop his own unique fighting style, which he calls "Hot Nunchuck Fury". Although it is hard to estimate if it is really a fighting style or just a fancy name.
- Part of his secret kata consists of Kamen Rider V3's henshin pose.
- In "Rise of the Turtles, Part 1", he was the first to taste pizza and so far he is the one who likes it the most. In "Panic in the Sewers", it is shown he will even eat it off the floor, or if it came from the trash, and confesses to loving pizza he finds on streets and rooftops.
