I was sent a PM on youtube asking me the following question: " Hi! My boyfriend's birthday is coming up very soon and i really want to get him an optimus prime toy that transforms into a green gorilla. The thing is, i have NO CLUE what he's talking about. He mentions ebay having it for 50 dollars but i don't know which it is... Please help!" offhand I don't know of any green optimus primals. I sent a reply saying as much, but I couldn't find out for sure because TFU is down right now. Does anyone know if there was ever a green Optimus Primal?
Other than maybe a knock-off of Primal Prime, I can't think of any green-variant of Primal. Purple, sure. Red, Clear, Black, Silver/Maroon here and there. There MIGHT be a bizzare TV-Magazine Campaign-Prize version, but good luck finding one. I don't even think there was one in green though... I hope I'm forgetting something though, and they can find their kid what he wants!
