Who would win in a fight between Sin and Vegnagun? Me and a friend had a
conflicting views, and decided that only you FFshrine fans can help us. (Just
between us though, i think Sin would definitly win. Vegnagun is weak as hell, and looks like a couple of coat hangers just twined together...)

I would say Sin as well.

Sin, not only is it more powerful, it has a better tune while your killing it...

vegnagon!!! he would eat sin with no problem

Sin, definitely. It was made to withstand attack by Spirans. However Vegnagun was made by Spirans to beat Sin, but because it was made by Spirans, it can be taken down. (The Spiran giveth, the Spiran taketh away in some ways)

Vegnagun is way easier to kill than sin. Just take a giant magnet up to him and watch him twitch away

lol, good one chewey. But the Celsius stays in the air how? Magnetic Propulsion (So say SE), so this would have made Vegnagun a whole lot easier!
