Why in these fights, does someone always claim rocket tag.

I don't think so.

I think this is a weird match up. I don't know if Shao Khans abilities are ever given anything outside of a fighting game.

Still given that, Aang is fast. I think Shao Khan is WAY faster. Even with Aang boosting his speed, Shao Khan is faster. Given how fast and how much combat expertise his opponents where. I don't think Aangs shtick of playing keep away would work on Shao.

I wish I could see Aang winning this fight. I just don't. Shao Khan would just overpower him, then beat him with that hammer of his. I don't think Aang has the spirit to actually kill Shao Khan.
