Ganondorf vs. Sephiroth with a twist
This is the One Winged Angel Sephiroth vs. one of his greatest rivals ever in game vs. Ganon the King of Evil.
This is AC Seph with his masamune and he has Fire3, Blizzard3, Thunder3, Quake3, Aero3, and that cool blast thingy Kadaj used in AC for spells.
This is Ganon in TP wielding the sword he used in Tp, tho you may use all versions of him in the games in the debate. He has all magic he has been shown able to use and has the Triforce of Power. He cannot go demon beast(Ganon) and is not invulnerable(tho I will put his durability at being able to survive Valoo's breath and fortress collapsing on him, but he is now by no means invulnerable).
The twist is that they are each handcuffed by an unbreakable brace on Ganon's left hand and Seph's right with a 30 foot chain connecting the braces. Try to come up with as many ways this can be an advantage for your character and disadvantage for the opposing character as possible.
Fight takes place in a flat valley in a large, rocky, and mountainous area separated from te rest of the world by a mystical and unbreakable fence set up by Dr. Phil.
I am rooting for Ganon but I will hold my reasons.
