This one took forever to make, but here it is: Omega Zero vs. Ωmega Zero! (decisive battle?)
Playing as Bass is awesome!
A very colorful fight
Isn't it great when you fully complete a game for the first time, then on your second playthrough you discover things you didn't discovered in your first time?
Using a patch to play as DarkMega and using a cheat to walk through walls makes this scene even better
