Tendril

Tendril (voiced by Chris Latta, who also voiced D'Compose) is a plant-like Inhumanoid who can regenerate his limbs. If a piece of him is cut off, it can grow into a copy of himself. Tendril is the least smartest of the Inhumaoids; he's more brawn than brain. Tendril's enemies are the Redwoods, led by Redlen.

According to Wikipedia, Tendril is an H. P. Lovecraft -influenced character resembling Cthulhu. A slimy hybridization somewhere between a mollusk and a walking mass of seaweed, he can regenerate his vine -like limbs — large enough pieces will even grow into new Tendril monsters — and he is able to alter his size at will. More berserker brawn than brain, intelligence is not this creature's strong suit. He exercises a slurred screeching in his speech, is clumsy and flailing in his movement, and has less-than astute powers of observation. Nonetheless, his regenerative powers, along with his sheer strength and aggression, make him a dangerous foe.
