Most depictions of X being angry in my art is either played up because it's not written in canon, a facade to misdirect you, or because it's misinterpreted.
When X is truly upset, it's not in your face about it.
The difference is that X wouldn't be able to win, as they are more capable and in control than the victims in X's games.
I really think only Sonic could beat X, because they're sort of mirrors in a way. It's a test to see who can keep pushing themself further, who can get back up again.
