Quarter-Finals! Mega Man X vs. Cloud

I don't remember X having access to ALL of his upgrades from ALL of the games in a single game, so stfu.

I believe the rules were stated as a character having access to all abilities and features specifically for that character in all games (s)he participated in.

As just stated, Cloud has access to all of his weapons and abilities. However, none of his abilities included switching weapons mid-fight.

X has access to all of his features from all of his games. (Might I add, nobody has included the Marvel vs Capcom fighting games in any of this.) X has the ability to switch weapons on the dime, and he can use this in the fight.
