Character: rocketchu

Rocketchu is a popular Pokemon fan character, and their depiction varies wildly depending on who is drawing them.

The original Rocketchu was created by the artist Skeleion under their old username, timmy-gost, in the late 2000s.

Her name is actually Ash, though she is more commonly known as simply Rocketchu, and she is an evil female Pikachu who works for Team Rocket. Her design varies based on the artist, but she is commonly seen wearing a black hat with the letter R on it, and a black collar with a red R hanging from it. The tip of her tail is black.

She is perhaps most well known from timmy-gost's AMV of the character.
