I call it "Rampanzee"
The name is a mix of "rampage" and "chimpanzee". It was the first name I thought of but people seem to like it for some reason :s
Ah, people on YT seem to think that he looks too much like a dog. I haven't changed it much from Primeape, all i have added to his face is a mouth and little horn things. But maybe it was the big teeth that made it that way...even though apes do have big teeth like that...hmm..oh well.
It has a very powerful punch and can even knock down a building with a single blow. They are very hard to train as making it angry or upset will make it go into a full blown hissy fi- ..er i mean rampage!
