Character: Usokkie (Kin`ya)

Sudowoodo is a bending, bipedal creature vaguely in the shape of a tree trunk. It has a double-pronged protuberance on its head, tiny feet, a simple face, and a pair of three-fingered hands where the fingers are green spheres resembling leaves on a tree. Although Sudowoodo pretends to be a tree, its body is made not out of wood, but rock. It uses this as a form of camouflage, hiding among forest areas to avoid being attacked by enemies. Additionally, its signature technique is Mimic, which allows it to copy enemy attacks. It earns its classification as the imitation Pokémon through these practices.

In the winter seasons, when trees are either white with snow or have had their leaves fall off from autumn, Sudowoodo is easy to spot as a fake because its hands remain green, making winter a more dangerous time for Sudowoodo to be in the presence of foes. Also, as a creature whose composition resembles rock, Sudowoodo hates water, so it will disappear and seek shelter when rainfall begins. In the video games, it often blocks areas until sprayed with water, which causes it to battle. In Pokémon Diamond and Pearl, the twig-shaped appendage atop a Sudowoodo's head is larger on a male than it is on a female. The origin of its name is: Pseudo (False) + Wood.

The Old Man's Sudowoodo was seen standing beside him. Goh's Grookey jump up on it's branch on the top of its head.

Brock's Bonsly evolved into Sudowoodo after it escaped from a cage that Team Rocket caught it in.
