Pichu have diamond-shaped ears on the top of their head, with the edges being black and the interior yellow. Underneath their head is a black pattern, that somewhat resembles a collar. Their tails are completely black, and resemble a small lightning bolt, similar to its evolved forms, which are larger. Pichu also have round, pink sacs on their cheeks, used for storing electricity.

Pichu have the special ability Static. This allows for a 30% chance that an opponent will become paralyzed if it lands a physical attack on Pichu. Pichu, like its other forms, is capable of storing electricity in the pink sacs on its cheeks. Being a baby Pokémon however, Pichu can not store as much electricity as its evolved forms. It will shock itself if any electricity leaks out of its cheeks.
