Deathblade's "Faster than light" edges

Okay,

Winner: Kabuto. Well I might as well get straight to the point. I'm going to go with the others on this and am going to give it to Kabuto. As Wass and Beast have said, Kabuto has actual weapons at his disposal and while The Flash may have an advantage with the Speed Force, it will not be enough to secure the win. Like what Wass said, The Flash uses his own body as a weapon and even if Kabuto does make a mistake in the battle, he can travel back in time to prevent it from happening in the first place.

My Prediction

Kabuto: 1900

The Flash: 1100
