Wobbuffet

Wobbuffet is a Psychic Pokemon that evolves from Wynaut starting at level 15. In Super Smash Flash 2 it can be released from a Poké Ball to aid a player during battle.

Pokémon description
Wobbuffet is a tall, cyan Pokémon with a soft body. Its eyes usually appear scrunched, and it has a jagged upper lip. The female Wobbuffet has a red marking on its mouth that resembles lipstick, while the male does not. It has flat arms that are wider towards the tip and four stubby legs at the base of its body. There are two eyespots on its black tail. Its eyespots are revealed to be capable of blinking and looking around using its tail in the Pokémon Stadium series. Wobbuffet is very protective of its tail, to the point where it will suddenly turn uncharacteristically aggressive if the tail is attacked.

Wobbuffet is usually a docile Pokémon that will never attack first. However, when it is attacked, it will inflate its body and initiate a counter-strike. When two or more of this Pokémon meet, they will attempt to outlast each other in a battle of endurance. However, since neither is able to attack, they may compete to see which can last without food. Because of its overprotective nature regarding its tail and hatred of light, Wobbuffet lives in dark caves.

In Super Smash Flash 2
As stated above, Wobbuffet can be released from a Poké Ball. Once released, Wobbuffet will use Counter, staying in place, and, upon getting touched by an active hitbox, will start shaking back and forth, similarly to the Flipper item. Opponents who approach Wobbuffet while it is shaking will get hit, with moderate knockback.

Wobbuffet is the only Poké Ball Pokémon to display actual gender differences as there are chances to release either a male or female Wobbuffet during a match. While both genders use the same move and behave similarly, there are some subtle differences between the two; the female Wobbuffet has its characteristic lipstick-like red marking on its considerably smaller mouth, is one-pixel shorter than the male and has a lower crotch.
