Loboan

Loboans are werewolf-like aliens from the moon Luna Lobo that can split their mussels 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). Like all the species in the Anur System, the Loboans and their homeworld is under the control of the Ectonurites.
