Akorec

The Alpha predator of Trammis III, is smart and powerful, capable of fighting even Rancors on even terms. Veteran and adult Akorecs may even be more powerful, and able to easily take down a Rancor.

They look like a cross between nowaday T-rex and Allosaurus, the younger ones appearing more Allosaurus then T-rex and the adults looking more like a T-rex.
