One of few people who could beat Sephiroth

Almost every gaming nerd knows Sephiroth. Probably the most well-known video game villain. He's super powerful and ruthless, has a ridiculously long sword, attempts to drain the planet of its energy with the aid of the Black Materia and its cataclysmic power referred to as "Meteor." And I'm sure I'm not the only one to have imagined who could possibly take him in a battle.

Nobody came to mind, until I got my hands on Shin Megami Tensei: Persona 3 FES. There is an optional boss (which means that they're more than likely tougher than the final boss) named Elizabeth. This woman is actually the main characters ally, but she soon longs to find out who she really is and asks you to fight her. She may seem weak, but don't let the elevator attendant get-up fool you, she is insanely powerful. She also has "rules" to her fight and if you break them, she will kill you instantly, but these rules are never stated and you would have to figure that out yourself.

She also has a particular pattern to her fighting and if you cant recognize it, you might be killed by her 9999 damage dealing attack. You may think Sephiroth would have the upper hand with his swordsmanship and that Elizabeth's weapon is a book, but she uses that book to summon "Personas" that can do enormous ammount of damage or heal her fully.

I should mention this is MY opinion, so do not start flamming me if you disagree. This really was just for fun, so if you're a huge nerd, you should try imaging if anyone could defeat Sephiroth in a battle.
