Deino is a small blue skinned quadrupedal Pokémon with black fur covering its head and neck which conceals 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.
Gender differences
None.
Special abilities
Deino have the vigor and energy to bite constantly and without stopping.
Behavior
Because they are blind, Deino will bite at anything. They never stop biting, and are therefore dangerous to approach without taking precautions. They will also ram anything, ensuring that they always have bruises all over them.
As seen in The Lonely Deino, Deino may rear up on their hind legs when they are happy.
Habitat
Deino primarily lives in caves with abundant water sources.
Three Deino made their debut in The Lonely Deino! under the care of a Day Care owner named Bobby who was looking after them for their Trainers. Two of the Deino were very rambunctious while one of them was shy and refused to eat. Iris tried to use her experience with Dragon-types to help it feel more comfortable around strangers.

Origin
Deino is based on a dragon, specifically an infant form of Yamata no Orochi. Its blindness and the fact that it is only found inside the Victory Road cave may mean it suffers from subterranean blindness. Deino may also be partially based on various cave salamanders due to their blindness and that they are found near bodies of water in caves.
Name origin
Deino may be a combination of dino (informal name for dinosaur) and ein (German for a, and part of the German for one, eins). It may also derive from δεινός deinos (Ancient Greek for terrible). It may also refer to dinosaurs such as the Deinosuchus and Deinonychus. Deino was also the name of one of the Graeae who, in Greek mythology, were three sisters who only had one eye between them, meaning that while one had the eye, the other two would be blind.
Monozu may be a combination of mono (prefix meaning one) and 頭 zu (head). Its full name literally means "one head".
