A small, blue-black Pokémon that looks like it has a Beatles-haircut. It likes to eat anything, and it doesn't care what it is. It learns its surroundings by biting as well, and by tackling too. It evolves into Zweilous, and its final evolution is pseudo-legendary Pokémon Hydreigon.
Deinos might look cute, but they're more dangerous than you can imagine!
