What guest character do you like the most in any fighting game?

I like Gon in Tekken 3, and Arnie as both the bad and good Terminators in one of the WWE games.

Some fighting games have very unusual choices for guest characters. One of the main antagonists in The Walking Dead called Negan for example, appears in Tekken 7 as DLC. And while he is a popular character on TV, I think he should have really been included in a Mortal Kombat game instead. Those games are very gruesome, indeed. He would have fit right in there.
