Avi is a great white dragon that hatched from the egg that Yoshimitsu Reigen possessed, therefore encouraging Avi to make Yoshi his master. Avi is one of a trio, being close to fellow dragons Nettlebrand and Quicksilver.
Avi is a great white dragon with spines and sharp claws. His wings are of a huge size and his white scales are spotless when clean. He has a very long tail.
Avi is aloof and calm, having a cool and level head. However, it is hinted that Avi may be a bit bloodthirsty, or at least that he is very eager to participate in a battle. Avi and Yoshi are very close, having some kind of a "quiet understanding" of one another without really needing much outward interaction. The two are also very hard to part from one another.
