Super Bebop & Mighty Rocksteady is a season 3 episode of the 1987 animated series


Bebop and Rocksteady are climbing the tower atop the Channel 6 News building in the middle of a thunderstorm. Rocksteady is carrying Krang's newest creation: the Mesmerizer, a device that will hypnotically enslave everyone in New York City to serve Krang and the Shredder. The two are successful in setting up the Mesmerizer, and shortly afterwards the people at Channel 6 News (April, Irma, Vernon, Burne, and an anchorman) are put under its control. This causes a great deal of confusion for the Turtles and Splinter, since mutants are unaffected by the Mesmerizer's rays. They quickly deduce that Krang and the Shredder are behind the news crew's behavior.

Shortly after setting up the Mesmerizer however, a bolt of lightning frightens Bebop, and he, Rocksteady, and the still-active Mesmerizer crash through the roof of the building, exposing Shredder's plan to the Turtles, who quickly spring into action. By the time the Turtles arrive, the mutants have awoken and have realized the power the Mesmerizer gives them. Bebop and Rocksteady try to use the hypnotized news cast to protect themselves, but when the plan backfires, the Mesmerizer is broken in the scuffle. With the device disabled, the crew snaps out of their hypnosis and Bebop and Rocksteady make a quick escape, with Burne quick to blame the Turtles for the commotion.

Fed up with the constant failures of Bebop and Rocksteady, Krang has them both cloned into robotic doppelgängers known as "Super Rocksteady and Mighty Bebop." Ten times stronger and smarter than the originals, Super Rocksteady and Mighty Bebop quickly dispose of their fleshy counterparts, which impresses Shredder. Now equipped with an amulet that will shield him from the Mesmerizer's influence, Shredder leaves with the new robots at his command, unaware that the device is still broken. The real Rocksteady and Bebop remain behind, sulking.

Meanwhile the Turtles take refuge at a local pizzeria, keeping a close eye on April and the Channel 6 building. As they're eating, Shredder and the robot clones make it into the lobby, and Shredder leaves Super Rocksteady and Mighty Bebop to guard the entrance while he goes off to setup the Mesmerizer himself.

However the broken Mesmerizer's effects quickly begin to show. Rather than enslave the population, the victims mentally regress to their childhood, and their spoiled behavior makes them impossible for Shredder to control. The Turtles make their way into the Channel 6 building, but they are confronted by Super Rocksteady and Mighty Bebop. The robot mutants swiftly overpower the Turtles and drive them from the building. They attempt to scale the building's exterior, but are knocked down by the robots as well.

Krang learns of the Mesmerizer's damaged effects and thus is forced to send the real Rocksteady and Bebop to assist Shredder by bringing him a schematic disk. The Turtles manage to steal the disk from them and find that it is capable of disabling Super Rocksteady and Mighty Bebop. As the real mutants are left to "fix" the Mesmerizer without the disk, they damage it even further, causing its victims to starts acting like dogs and later monkeys, much to Shredder's annoyance. The Turtles return to face Super Rocksteady and Mighty Bebop once again, but thanks to the information on the disk, the Turtles are able to override the control over the robots and instead, use them against Shredder.

With the Mesmerizer off the tower once again. Super Rocksteady and Mighty Bebop explode. However the Shredder manages to grab the Mesmerizer. With the distraction, Donatello notices the amulet protecting him from the Mesmerizer's influence and quickly manages to swipe it off of him. Now no longer protected, Shredder falls victim to the Mesmerizer, forcing Bebop and Rocksteady to try to bring it back by climbing up Channel 6's tower after him, since Shredder now believes himself to be an ape. Ultimately, their combined weight is too much for the tower to handle and both Shredder and the mutants plunge off the building's rooftop and onto a Pizza Stand, much to the Turtles' horror. Fortunately, the Mesmerizer is also destroyed by the fall.

With Shredder's latest plot stopped, The Turtles, April, and Irma celebrate by eating pizza. However, April gets one last laugh when she notices Vernon acting like a monkey, much as he did under the Mesmerizer's control.

Animation Errors

  • Once he installs the Mesmerizer on the tower, Shredder's skin turns a lighter shade of tan, and his vest turns a darker shade of grey for some reason.
  • When Krang wonders aloud if his Mesmerizer's been damaged, his brain-body expands and fills the robot body's cockpit, and he's drawn with less detail than usual in the shot.
  • Burne Thompson seems a lot shorter than usual in some shots. He's about the size of a midget when Shredder contacts Krang to complain.
  • Krang's eyes are white when he's responding to Shredder's complaint about the Mesmerizer. It's supposed to be lilac.
  • When Bebop and Rocksteady step out of the Tunneler once it crashes into a dumpster, they are drawn way too small. If you compared them to the size of the dumpster as is, they'd barely reach it in height.
  • The disk Rocksteady holds up once the Turtles capture them is a rectangle instead of a square.
  • There is one scene where Donatello analyses the disk and the animation turns rather cartoonish, even more so as usual. For example, in that scene, Donatello seems to be moving a lot more fluidly than usual, gains wider eyes, and is wearing a rather goofy grin on his face that you'd only see in a Disney cartoon. After that scene ends, the animation reverts to normal.
  • When Donatello says, "Here goes!" his bandanna is tied differently, making it look almost like rabbit ears.
  • When Burne falls off of the hanging light, his body gets bigger and bigger as he falls. He's absolutely humongous when he finally lands.
  • When Donatello used the remote control to take over the Super Mutants, his teeth were colored red.
  • Michelangelo's belt is colored the same as his plastron and the bottom of the plastron is colored green when Donatello analyses the Mesmerizer's schematics in the Turtlevan.
  • When Leonardo and Donatello are outside the Channel 6 building patrolling, Leonardo is seen with four fingers when he's holding his turtle com.
  • When Raphael pulls out his sais to trap Rocksteady and Bebop in the Channel Six doors, he pulls his sais from the back of his belt instead of the front.

Continuity Errors

  • There's a scene where the reprogrammed super clones are dancing, and Super Bebop grabs Shredder to dance. Later on, Shredder is seen turning around, the super clones enter the scene dancing, and the animation is re-used again.

Logic Errors

  • Why didn't Shredder and Krang wait for the weather to improve before sending anybody to install the Mesmerizer? Are mutants immune to getting hit by lightning, too?
  • You'd think by this time, after all of the shenanigans that Shredder had put New York city through, that anybody with half a brain would recognize him. You'd also think that Shredder, being the leader of a clan of ninjas, would be more discreet about his operations by now. But no, Shredder decides that instead of sneaking to the top of the building and installing the Mesmerizer in secret where it's very unlikely he'd be caught, he decides to crash through the lobby instead and take the elevator. What's worse is that it's crowded, and not one person reacts to the evil super-villain now sharing an enclosed space with them.
    • Oh, and also noteworthy is the big bad guy also apologizing to everyone when he gets inside. Most likely done for comedic effect, but, all the same.....*FACEPALM*
  • Vernon kicks Shredder in the shins whilst the latter is wearing metal, spike-studded shin-guards...and somehow, Shredder still feels pain while Vernon avoids getting his foot impaled. Although, we do see Vernon, hoping around in pain shortly after kicking him...
  • If Krang despised Bebop and Rocksteady's moronic antics so much, why did he upload their brainwave patterns into those robots? Wouldn't it have been easier just to program those robots to act competent?
  • Why did the Mesmerizer cause the super clones to explode?
  • Right before Donatello ambushes Shredder, Shredder and the mutants are looking to the side at...something. What are they looking at?
  • When the hypnotized Shredder scales the tower with the Mesmerizer, he's climbing using only one hand, and neither of his legs. Is that even possible?


  • While the episode is titled Super Bebop & Mighty Rocksteady, the clones are called Super Rocksteady and Mighty Bebop.
  • More so than any other episode so far, this episode is rather blatant with the fourth wall-breaking. Shredder, Irma, Krang and the Turtles all face the camera when delivering dialogue at some point or the other in this episode, in some cases, asking questions that sound as if they're directed at the audience watching them.
  • For an episode named after them, Super Bebop and Mighty Rocksteady don't really do much of anything, do they?
  • Bebop is scared of lightning. As would anybody be when climbing a tall, metal structure in a thunderstorm, really.
  • According to his own dialogue, Rocksteady hasn't taken a bath in a month. As least we now know why Shredder wears a mask inside of the Technodrome, and Krang's probably thanking his lucky stars the animators never gave him a nose.
  • When Krang introduces the robotic versions of Bebop and Rocksteady, the German subtitles refer to Super Bebop as "Wonder-Bebop".
  • Shredder's movements after he becomes hypnotized suggest that he thinks he's a gorilla.


Shredder: But what choice do I have? Only mutants are immune to the Mesmerizer's beam! Humans like myself can't be near it when they set it off!

Krang: You don't have to explain it to me, I invented it, remember?

Shredder: I wasn't explaining it to you....(turns to camera and points) ....I was explaining it to them.

- Krang and Shredder on expositions and breaking the fourth wall.

Shredder: D'ooohhh....those moronic mutants! WHAT ARE THEY DOING?!

Krang: Failing, Shredder. It's the only thing they know how to do!

- Shredder should never send punks to do a ninja's job.

Bebop: Hey....dis brain control thing really woiks!

Rocksteady: Hurr...lucky we don't have to worry about that!

- Sometimes, these jokes just write themselves.

Irma: Uh....what happened to us?

April: I have the distinct feeling that we were out!

Irma: Where'd we go? ....and did we meet any cute guys?

- No, poor Irma. You did not.

Reporter: Nyeh, nyeh, nyeh, nyeh, nyeh, I'm on TV and you're not!

- Hearing this said in a dignified voice is comedy gold.

Shredder: Attention, slaves! I am your master and I command you to obey me-

(interrupted by Vernon crying)

Vernon: I want my milk and cookies!

Shredder: You want what?

Vernon: You heard me. I get awful cranky if I don't have my cookies! *kicks Shredder*

- Shredder attempts world domination and fails miserably, part 1.

Burne: Hey, mister! Help me change this channel. I wanna watch cartoons!

Shredder: No! I am the master. You are the slave! And I say: "NO CARTOONS."

Burne: I wanna watch cartoons! I wanna watch cartoons!

(chairs collapse on Shredder)

Burne: Now look what you did! You gave me a boo-boo! AAAAAAAAHHHH!!!

- Shredder attempts world domination and fails miserably, part 2.

Krang: How many times are you imbeciles going to fail me?

Bebop: Oooh....LOTS more times, boss!

Rocksteady: Yeah! We ain't the least bit tired!

- Well, at least they know their lot in life, huh?
