This large spikier than usual gorilla-type is on top of a circular tank reached by a ladder and sloping ramp at the top.
He zips around the fenced-in circular space and emits a ground-effect that’s pretty much instantly lethal, and that seems to do equal damage whether I’m on the ramp or the top of the tank proper.
Doesn’t seem to be much on him online either. Any help appreciated, thanks!
