|~ Bebop and Rocksteady's catchphrase.|
While earlier comics and cartoons shown both of them as stupid, here only Rocksteady is stupid and Bebop has sharper common sense frequently correcting Rocksteady.
Rocksteady is portrayed by WWE wrestler Sheamus, while Bebop is portrayed by Gary Anthony Williams.
Role in the film
At the start of the film, Bebop and Rocksteady are transferred between prisons alongside the Shredder by Casey Jones. The two criminals introduce themselves to the Shredder, claiming to be big fans of his work. When the Foot Clan arrives to Casey's convoy to get the Shredder with the Teenage Mutant Ninja Turtles on the Foot's heels, Bebop and Rocksteady dispatch Casey and hijack the convoy.
Afterwards, Bebop and Rocksteady are seen at their favorite bar, musing that with the Shredder gone, they can start their own Foot Clan. Just then, the Shredder arrives with the Foot, revealing that he's "looking for errand boys" for his own goals.
The Foot, with Bebop and Rocksteady in tow, approach Baxter Stockman to synthesize Krang's mutagen for a mutation. When the mutagen is synthesized, the Shredder shoots Bebop and Rocksteady with it, mutating them into their "animal ancestors." The newly mutated criminals help the Shredder locate two parts of Krang's teleportation device and succeed.
During their first battle with the Turtles which was taking place inside an airplane, Bebop punches Leonardo while Rocksteady tackles Raphael. When Raph throws Rocksteady away, Rocksteady resorts to using a machine gun in an attempt to shoot the Turtles to stop them from tackling Bebop. Rather than killing any of the turtles, Rocksteady destroys the plane causing it to start falling. Bebop scolds him for this mistake, which Rocksteady admits to. As the plane crashes into a river, the battle continues, with Rocksteady commandeering a tank (which, this time, helps Bebop). The turtles then fall down a waterfall at the end of the river, and they don't battle Bebop and Rocksteady again in the movie.
In the final battle when Krang finally arrives on earth, Bebop and Rocksteady take on Casey Jones. Jones manages to subdue the two by trapping them in a crate with grenades.
