Species: tigerchu
An anthro, implicitly female, Pikachu with tiger features.
The inspiration for this species is an interview with The Pokémon Company president Tsunekazu Ishihara, in which he claims that Nintendo of America suggested design changes for multiple Pokemon species prior to the franchise's international debut. Ishihara described a suggested redesign for Pikachu as resembling "a tiger with huge breasts", going on to compare it to the costume designs from Cats.
The original design is not publically known, and all images under the tag feature artist's renditions of the creature.
