Armadillo bear

The armadillo bear is a chimeric hybrid of an armadillo and a bear.

History
Armadillo bears never made an appearance in the show; they were only mentioned by Toph as one of the bear hybrids Earth King Kuei must have had instead of his odd, non-hybridized bear. An armadillo bear was later seen when it was considered a "monster" by a Fire Nation village. Appa later managed to defeat the armadillo bear and was hailed as a hero by the village.

Connection
The armadillo bear is a hybridized animal; a combination of an armadillo and a bear. It is one of the more noteworthy bear hybrids in the Avatar world, as mentioned by Team Avatar.
