Loboan

Loboans are werewolf-like aliens from the moon Luna Lobo that can split their mouth into four parts, and perform a "sonic howl". They also seem to possess two different "base" colors: green (seen when Ben transforms into a Loboan) and Purple (as seen on the Yenaldooshi) (also like the mummy that attacked Ben, the Lobans also might be mutated with the purple stuff). Due to the fact that the Yenaldooshi and Benwolf appear identical, Loboans either mature quickly or the Yenaldooshi is a juvenile. Like all the species in the Anur system, the Loboans and their homeworld is under the control of the Ectonurite.

Trivia
