K’Vathrak (2012 TV series)

The Newtralizer is a character that debuted in Teenage Mutant Ninja Turtles (2012 TV series). He is an amalgam of characteristics of a rejected toy design for playmates by Ryan Brown and a character created by Ciro Nieli whilst in elementary school. Due to The Newtralizer's costume, he is likely a parody of Marvel's The Punisher with inspiration provided in part by Judge Dredd.

Appearance
The Newtralizer is a heavily armored, mutated Fire Belly Newt. He is primarily black, with an orange underbelly. The coloration of his underbelly forms a skull pattern. The Newtralizer is very muscular and bulky, easily dwarfing the Turtles. He appears to be intelligent, capable of using Kraang equipment and weaponry without issues. Thus far, however, he has not displayed the ability to speak.

His armor set includes a belt, a pair of shoulder plates (the right plate is far larger than the left), two straps that connect the belt and shoulder plates, a pair of armored bracelets, a pair of leg holsters with pouches and ammo types attached to them, and a pair of axe blades attached to his tail. He also wears a backpack with an antenna sticking out. It is likely a radio, but its exact purpose is unknown. He also carries three Kraang tentacles as trophies tied to his belt.

Operation: Break Out
The Newtralizer's first appearance in the series is in Operation: Break Out, as a prisoner of the Kraang. Donatello inadvertently releases him from his cell when he picks the lock to a secret Kraang lab, and he promptly goes on a rampage. The turtles ultimately manage to defeat him, but he survives and escapes from the lab.

Metalhead Rewired
Newtralizer's next appearance is in Metalhead Rewired as one of the detained mutants in the Kraang prison. After Metalhead frees all of the mutants, he escapes from Kraang captivity once again. His current whereabouts are unknown.

Newtralized!
He will Team up with Slash join or face the Turtles in the episode of NewTralized Casey Jones will face Newtralizer

Abilities
Like most mutants that start as animals, he has increased intelligence, though presumably not enough to speak, but enough to operate advanced weaponry. His weapons include lasers, missiles, sawblades, exploding mines, and he also has blades attached to his tail. The Newtralizer is capable of constricting a foe with his tail, and able to eat a Kraang, minus the armor, whole. He possesses incredible strength and speed. He is also shown to be quite durable, with or without his armor, as he was able withstand attacks from numerous Kraang lasers, Leo's katana, Raph's sai, even after getting crushed by Mikey attempting to drive a car, he still survived without any visible dents, bruises, scratches or an injury of any kind.

Trivia

 * The pattern on his chest resembles a skull
 * The Newtralizer is capable of fitting a whole Kraang in his mouth. His tongue is white.
 * His boomerang resembles a Predator smart-disc.
 * He is intelligent enough to strap on Kraang weapons and operate a gun.
 * Ryan Brown created a design for an action figure of a character named The Newtralizer for the original toy line, which was rejected. The two characters are completely unrelated other than their name/species and hatred for Kraang/Krang.
 * The Kraang he attacked to retrieve his weapons called him criminal and Shredder called him "the Kraang alien creature" which possibly hints that he is from Dimension X.
 * Donatello gave him the name "Newtralizer", but asked Kirby O'Neil not to mention it when Mikey's around, as he prefers to name their foes.
 * Though the Turtles and Newtralizer's first encounter was as adversaries, it has been hinted that he indeed will become an ally to the Turtles in future installments of the Nick show.
