Physiology:
Serperior is a primarily pale-green, snake-like Pokémon. Serperior has curled pale-green patterns on the sides of its face and snout, and small, pointed yellow extensions on the back of their heads. Its face and upper neck are white-colored, and curled, tendril-like darker green extensions spread out from the sides of its lower neck, forming a curling pattern lower down the body, resembling a fancy collar. It has narrow red eyes, and small, pointed teeth on its lower jaw. The upper section of its body is dark green, and the lower pale green. Curled yellow patterns adorn its body, and a sprig-like feature of several leaves tip its tail. It has lost its legs completely, and now only has small, stubby hands.
Abilities: Serperior is able to amplify sunlight inside its body. Its piercing stare can stop opponents in their tracks. It's long, flexable body also proves quite useful in making it's foe/prey unable to move or flee.
Behavior: Serperior holds its head high pretentiously while fighting and tends to stay elegant at all times. It doesn't take most opponents seriously, unless said opponent is particularly powerful. As such, it seems to pay little attention to anything around it, only those it sees fit for something.
This particular Serperior seems odd. She changes to he, and he change back again. At one moment, it's large enough to devour two fully-grown adults and still have room for more. The next, unable to eat any more then a small child without immobilizing itself. It has a fluctuating personality... yet one thing remains unchanged. It will be hungry, and it will try to eat you, wrapping you up in pudgy warm coils... before adding you too them.
