"The Flash" executive producer Andrew Kreisberg has confirmed that DC Comics' character 'Gorilla Grodd' will return to the series, following a brief cameo in the episode "Plastique," played by stunt performer Simon Burnett ("Rise Of The Planet Of The Apes"):
'Gorilla Grodd' debuted in DC Comics "Flash" #106 (April–May 1959), created by writer John Broome and illustrator Carmine Infantino.
"...originally an average ape, 'Grodd' was imbued with super-intelligence by the pilot of an alien spaceship, that crashed in his homeland of Africa. Grodd's psionic abilities allow him to place other beings under his mental control.
"Grodd can also project telekinetic force beams, telekinetically transmute matter and transfer his consciousness into other bodies..."
