This article is about the cybernetic clones of Rocksteady and Bebop. For the episode in which they debuted, see Super Bebop & Mighty Rocksteady.

Bebop and Rocksteady were charged with the task of placing a new device called the Mesmerizer on top of the Channel 6 News Building. The Mesmerizer was created by Krang with the intent of controlling the will of all of the humans in the world - mutants were unaffected by the device, and thus the duo were the prime candidates for its installation. Bebop and Rocksteady initially succeed, but fall through the roof of the building with the Mesmerizer in hand, and are subsequently chased off by the Ninja Turtles.

Shredder is livid at his two minions for failing once again. Krang straps the two mutants down and uses a device to create cybernetic super-mutant clones of them. Dubbing them Super Rocksteady and Mighty Bebop, Krang explains that they are stronger and more intelligent than their organic counterparts. Krang has also made and amulet that protects Shredder from the Mesmerizer, and the two super-mutant clones accompany Shredder to Channel 6 once more. Little do the villains know, however, the Mesmerizer was damaged in the previous mission.

The newly installed Mesmerizer affects humans' brainwaves, only this time, instead of making them subservient to Shredder, makes them behave as children. The Turtles, who are in a pizza parlor, witness the waitress and chef, as well as the Channel 6 anchorman on TV, acting peculiar, and deduce that the device has been implemented again. Rushing to the Channel 6 building, they are denied access past the lobby by Super Rocksteady and Mighty Bebop. A small scuffle ensues, and Mighty Bebop lobs a gigantic globe at the Turtles, forcing them out the doors. The globe bars them from entering again as it is now blocking the doors and unable to be moved.

Some time later, the Turtles attempt to climb the building with suction cups. The two robots ram the building with their shoulders until the Turtles fall off.

Shredder begins complaining to Krang about the status of the Mesmerizer's effects. Realizing that Bebop and Rocksteady have broken the device, he orders them to take a disc with the schematics of the Mesmerizer to the Channel 6 building so that it can be repaired. Bebop and Rocksteady accidentally take the disc with the blueprints of Super Rocksteady and Mighty Bebop, however. The two encounter the Turtles again, and lose the disc to them. Donatello realizes the disc's worth and sets out with a plan.

Rocksteady and Bebop damage the device even further, causing more erratic behavior in the humans, such as them impersonating animals. Donatello reprograms the supermutants, causing them to now waltz with Shredder. Raphael tosses his sai at the radio tower, knocking down the Mesmerizer. Upon its crashing to the rooftop, the two robots short-circuit and explode.

Action Figures

Two action figures slightly resembling Super Rocksteady and Mighty Bebop were produced by Playmates Toys in 1993. Simply termed Robotic Rocksteady and Robotic Bebop, respectively, the mechanical duo more or less retained their background from the cartoon as cybernetic doubles of the original mutants (although Shredder was credited for their creation, as opposed to Krang, in the cartoon). Physically, the figures were shaped similar to their animated counterparts, but differed in color scheme - some parts of their bodies that were metallic silver in the cartoon were swapped out for solid colors such as blue or red, and vice versa.

1995 saw the release of a figure called Warrior Rocksteady, which was a repainted version of Robotic Rocksteady. However, this figure's story involved him actually being the organic Rocksteady, transformed into a robot. A similar Bebop figure was planned, but scrapped.

Name confusion

  • The episode of the cartoon in which they appear is bizarrely named Super Bebop & Mighty Rocksteady, mixing up the adjectives in the characters' names.
  • In 1993, alongside the Robotic Rocksteady and Robotic Bebop figures, a figure called Mighty Bebop was released. This figure, however, was not in any way similar to the Mighty Bebop of the cartoon, but was instead based slightly on Bebop's superhero persona from the episode "The Adventures of Rhino-Man", Mighty Hog.
