Mel Gibson's William Wallace, but superhuman and a bit insane.

That's how I see Khan in this film. Avenging a dead wife against those responsible for her death, leading his people against an enemy to a better future, he is tactically brilliant and his bountiful ability attracts loyal followers, as does his supernatural charisma and affable personality. Khan is what Braveheart's William Wallace would might have been had he been raised as Edward I's adoptive son but rebelled when he learned he was really a Scotsman. He is also like Moses, but much more sadistic and not holy or humble at all. He probably saw himself as Moses at one point too were he real.

I don't know. I just saw both of these films and the characters seemed strangely similar to me, even in their physical appearance save that Khan is much older than Wallace was when he died.
