The Spy vs Zoroark? ( TF2 vs Pokemon. )
Just thought of this at like 6:30-ish, thought it'd be fun, and less absolute ass like my last idea.
Both fighters may use any/all feats, abilities, equipment and weaknesses from their respective franchises, however they will receive NO prep time, or just information on their opponent.
Also also, the fight will take place in 2Fort, at the end of a game of whatever game mode makes sense.
