None of the above. They will all be defeated by an AI smash player (smashb0t), who will be banned from entering the next year for not having thumbs (or a physical body).
The creator of the smash bot will then build mechanical thumbs and reenter smashb0t, who will be banned again for not being at least 40% human.
Smashb0t will then begin to incorporate biological components into itself until it is human enough to play smash, by this time it is 30XX and the only other living person who still wants to play competitive smash is mecha2king, whom smashb0t again beats handily.
Mecha2king goes onto /r/20XXbros the next day to john that his output port was receiving interference from smashb0t's thumb servos and that the gamecube emulation was directing frame data to his visual cortex at 16.68 ms instead of the community approved output rate of 16.67ms.
Starmada and PP-reconstituted-into-a-gorilla-body-MD both troll him using sock-puppet accounts.
