The main antagonist of the series. Sir Lewis Leon Paradim (or LLP for short) is the bald-headed CEO of RM Corp vows to take over the world through Krang Chips in the first half of the series, then seeks to become World President in the second half, all while attempting to discredit and destroy ZZ's heroic efforts. He is crafty enough to send a bomb-equipped robot duplicate of himself to his own birthday celebration, knowing that ZZ will be there (as seen in "Rock the Corp"). LLP also has considerable fighting skills of his own in "A Tale of Two Paradims" where he manages to fend off Ninjzz with fisticuffs and pushes Ninjzz to the ground.

The Corp's resident cyborg mad scientist who speaks with a lisp, and chief creator of the Corps' bots. His faith in said bots is high, and though they are destroyed on a regular basis, he becomes visibly dismayed upon learning that the Krang Chip-equipped 3A can be hacked (as seen in "You Can Bank On It"). Hiss has a personal hatred for ZZ, generally attempting to kill him outright with overwhelming firepower (but halting within range of media witnesses - "Lost"). Hiss often personally engages in battles, yet the Boyzz Brigade try to avoid injuring him. His name and personality could be references to the Nazi politician Rudolf Hess.

Paradim's second-in-command who holds romantic feelings for ZZ which sometimes conflict with her loyalties to LLP and the Corp. She doesn't share Dr. Hiss' confidence in RM Corp's bots, and thus will generally attempt to negotiate or threaten before resorting to violence. As fitting to her position, she has a far cooler mind than Hiss.

RM Corp Bots (3A type)

Although the RM Corp's bots are devoid of personality (and universally speak in the same monotone synthesized voice), there are a few common types.

3P - An enormous green robot that serves as power booster bot for "MDB" (see below).

Beast Bot - A special-purpose canine-like robot designed by Dr. Hiss to track and locate Ziv Zulander.

Green Bot - Green Bots are the Corp's standard soldier robots. They have stronger armor than Security Bots and are better armed, with a laser cannon on one arm and a set of pincers on the other, but behave in the same manner.

Humabot - Humabots are mercenary cyborg soldiers that work for the Corp in exchange for robotic upgrades.

Massive Destruction Bot - The Massive Destruction Bot (or MDB) is a class of robot that is one of Dr. Hiss's creations. Although there are several variants, the original prototype was nicknamed "Goliath". MDBs do not speak and usually require the Zulanders to deploy Jungle Fiver to do battle.

Private Police Bot - Also known as "P.P.B.", these well-armed robots featuring black and purple armor are a more advanced version of the Green Bot and are usually used for the personal protection of Corp staffers but are occasionally dispatched for open combat when needed.

Security Bot - Security Bots are the most common opposition ZZ and the Boyzz Brigade encounter in the first half of the series. Designed to monitor and patrol restricted areas, they have security cameras for heads and exposed joints which the Boyzz, especially Toolzz, frequently exploit for dismantling.
