Manon's Critical Art will always be my favourite; the singing, music and visuals are gorgeous. But for recency, a shout-out to how menacing Akuma is looming over you before he crushes your face between his fist and the floor.
The difference between JP's level 3 and CA is so perfect. In the normal one he's calm, collected, superior, exactly how he wants to be perceived, but when backed into a corner his real self comes out: literally calls you a cretin, disses your motivation, then smokes you while laughing like Darth Sideus.
nothing beats Akuma.....probably one of the best akuma finishers. They took the finisher of the wraging demon but also the one form street fighter x tekken.
