This achievement requires you to finish a
match with a level 3 hyper combo.
In the final round of a match, when your opponent's second character is near death (about 15% health or less), make sure your hyper gauge is at least at 3, then perform your character's level 3 hyper combo to win the match.
You will have to check the command list for your character's specific level 3 hyper, but here are a few of my favourites:

Dante:

Dormammu:

Firebrand:

Ghost Rider:

Morrigan:

Thor:
