Quan Chi's Fatality involving an asswhooping with the opponent's leg is pretty funny, but fairly out of character. It's almost like he got tired of manipulation and trolling and just said "That does it. I'm manipulating my foot up your ass!"
Nightwolf's Shoulder Ram. All that Mystical Native American shit with arrows, lightning, and stuff...and then he has one move where he just bum rushes the motherfucker. Okay...?
Takeda's Ronin Lightsabers. Retractable whips...exploding kunai...okay, he's a high tech ninja who kills at long range. So why these dual short lightsabers?
