While that is pretty awesome, I think nothing triumphs using Renzokuken on Jumbo Cactaur in FF8, remember laughing so hard when I seen it first, his little spin around with Squall bopping him around on top of his head.

or when you fight artemesia (Ultimecia) the last form and he gets so agressive and slashes so fast you can feel how he just thinks " just DIE already"

Killing two guards from above in an Assassin Creed ! Really satisfying

I love kill Joy with torture attack (first bayonetta): skip to 2:27

I'm gonna put something obscure here, but landing Aurora Execution or Nebula Storm in Saint Seiya: Sanctuary Battle (Senki) is really satisfying. They just nuke everything.

Maybe they all fear what will happen to it in the 5th installment of FF7 remake when you finally get it. Although, Catastrophe and Highwind were just as powerful.

Generally, Knights of the Round plus those limits made a mockery of the final 2 fights, if you had them all stored up ready.

On topic, in Tekken Forward/Down + Circle. Basically just a kick to the shins but stops people comboing and stuff. :)

Either one of these.
