Monsters

Monsters are the playable characters of King of Tokyo and King of New York. While they vary in many respects, they are all large creatures with a destructive nature. They rampage through their respective cities in an effort to become King.

Species
Each monster belongs to one species; mutant, invader, robot or Halloween. Mutants are existing creatures, mostly animals, which were altered into giant monsters. Invaders are creatures from other planets or dimensions that have traveled to Earth. Robots are mechanical creations, whether automatically functioning or piloted by a smaller being. Halloween monsters are themed after the holiday Halloween, and all appear to be mystical in nature.

The species mechanic was introduced in King of Tokyo: Power Up! and is shown on every monster's evolution cards. It is not currently used in any expansion, but is reserved for future expansions and tournament rules. King of Tokyo: Halloween introduced the Halloween species. Monsters which do not have official evolution cards also do not have official species.

Trivia

 * While monsters without official evolution cards don't have official species, many can be inferred. For example, as Orange Death was a regular carrot who became a monster, they would be classified as a mutant. As Iron Rook is mechanical, they are a robot.
 * While the invader species most obviously covers alien monsters, it also includes several magical/divine monsters. Cthulhu is an elder god, and Anubis an Egyptian god and both are invaders. Halloween Monsters are also predominantly magical.
