Hood Pups are a closed species similar to dogs, wolves, foxes, etc. For most of their lives, they wear some sort of hooded garment. The hood always covers their eyes when it's up, and has a color and design on it that shows the Pup's magic. The Pup's body may have any markings, colors, etc.
Young Hood Pups
Hood Pups are born with a hood covering their eyes, and while they are still young, it can't be removed. As a result, the first magic a young Hood Pup often learns is to be able to see while their eyes are covered.
Adults (Hood Up)
Adult Hood Pups have several differences from Pups. Their limbs are longer and they have large paws, as well as having long necks and (usually) large fluffy tails. Their buttons can change shape depending on their type.
Adults (Hood Down)
Currently, very little is known about what happens to Hood Pups when they put their hood down, since it is very rare.
The hood of a Hood Pup makes it harder for them to use their magic, so they can generally only do small things, such as see through the hood or, for example, a fire-type could create small flames. It is said that when a Hood Pup puts their hood down, it allows them to use their full strength. Even so, they rarely do so.
It is also possible for a Hood Pup to have the magic of another creature sealed into a special container that is attached at the collar area of their hood. These Pups need significant help to grow, and once they do, their hood is locked on so they can't take it off. They are extremely powerful, however, as they can use both their own magic and the sealed magic.
