Vent is easily one of the least popular “Megamen” but he’s still a very tough opponent. His speed is on a different level than anything you would find in Marvel or DC and his power is considerable. Dr Doom has gotten many power ups over the years, but they simply won’t be enough here. His armor won’t be superior to Vent’s and his projectiles will simply be overpowered by Vent’s charged shot. Vent wins.
