Tuxedo Masked

Whenever a main character in a TV series or movie, is about to die in a very dramatic way and is saved at the last possible second by an unsuspected hero.

Enemy: you're going to die Sailor Moon with a claw to the face! (Attacks)
Sailormoon: Noooooooooooooooooooo!
(Rose interrupts)

Enemy: WTF
Tuxedo mask: Not today evil doer! You just got Tuxedo Masked!
