During the "Opening Salvo" part of the "Secret Empire" storyline, Gorilla-Man appears in an underground lair where he was building his army of Gorilla-Men while operating under the alias of King of the Gorilla-Men. These Gorilla-Men are the results of gorilla heads being surgically-attached to human bodies. He then finds Robert Maverick who just turned back from his Red Hulk form. While attempting to pull Robert's head out of his body in order to strengthen his Gorilla-Men army, Gorilla-Man and his Gorilla-Men are attacked and defeated by Squirrel Girl, who unleashes her flying squirrels on his army.
