Deino

Deino is a small blue quadrupedal Pokémon with black fur covering its head and neck, concealing everything but its mouth from view. The fur around its neck also has six purple spots encircling it, which resemble bruises. The hair on the top of its head takes the shape of a single small horn. It also has a short tail that appears to be bitten off. As it is blind, it will bite at and eat anything that moves, and it has the vigor and energy to bite constantly and without stopping. It never stops biting, making it dangerous to approach without taking precautions. It will also ram anything, ensuring that it always has bruises all over it. As seen in The Lonely Deino, it may rear up on its hind legs when happy. Deino primarily lives in caves with abundant water sources.
