I'm just getting into Hunter x Hunter through Toonami, but based on what I've seen, I think having Goku and Gon team up, fight, or just doing something goofy would be fun to try in a meme if something comes up. As long as that's okay with you - I'm not familiar with Hunter x Hunter beyond the really early stuff, so I don't know if Gon changes drastically as the series goes on.
