Isn't it Castle Greyskull?? That's what it was originally called. I haven't followed the rerelease of these figures and didn't know they changed the name.
I still have a ton of the original figures along with Snake Mountain (microphone/voice changer still works!)
Oops.. I mispelled it. I dunno why I said hawk. Hmmm... That makes no sense ndd I can't attribute it to a freudian slip.
Edit: Oh I know why I wrote greyhawk. Thinking D&D for a second.
