Zweilous

Zweilous appeared in 2010 video game called Pokémon Black & White. Zweilous is a Hostile Pokémon. Zweilous has a ravenous appetite and exhausts the local food supply before moving on. Rather than working together, its two heads compete for food.

Zweilous is a quadrupedal two-headed draconian Pokémon. Two black wing-like appendages and a second head have appeared on its body upon evolving from Deino. Black scruffy fur covers both heads' necks and eyes. It has two claws on each front leg, as well as a stubby tail and two feather-like "horns" on both of its heads. Its round, plumper underbelly has two rows of magenta scales. Zweilous' belly is rounder and wider due to the fact that it is a voracious Pokémon that is constantly eating; its heads compete for food, so it eats more than necessary.
