Kecleon

Kecleon appeared in 2002 video game called Pokémon Ruby & Sapphire. Kecleon is a Color Swap Pokémon. Kecleon is a master of camouflage although it gets annoyed if it's disguise works too well and nobody notices it! The changing color of its skin can also reflect the state of its health or mood.

Kecleon is a bipedal, reptilian Pokémon that is usually green. On either sides of its head are yellow frills, which are connected by lines to its yellow lips and rings around its eyes. There are small ridges on its shoulders and a red zigzag stripe around its midsection. The hands and feet have three short digits each, and it has yellow soles. It also has a long skinny tail that is usually curled tightly in a spiral.

Kecleon is able to change the colors of its body at will, and is known for frequently using this ability to camouflage itself. However, it is unable to change the color of its red stripe. Its color also changes based on its mood and health, darkening in color with better health. By using camouflage to appear almost invisible, it can sneak up on prey and ensnare it with its long pink tongue. If unnoticed for too long though, it pouts and may never reveal itself. A purplish variant has been seen in the anime and the Pokémon Mystery Dungeon series; whether this is an example of it changing color or simply a different kind of Kecleon is unknown. This Pokémon lives in tropical and temperate forests.
