Dante wins
use quickheart+quicksilver+ifrit as his gloves and Agni/rudra as his swords+devil trigger to lessen the damage intake if venom manages to hit dante. Incinerate the whole arena with dance macabre of agni/rudra where the battle takes place = venoms ashes lying somewhere in the arena or dante wins fatality pwn ez kill
facts from the game dmc dmc2 dmc 3
quick heart gives dante breakneck speed equivalent to any supers speed
quicksilver gives even more speed by slowing down the time (one second elapse in real time=10 seconds to dante) which gives enhances quick heart 10x more
sparda form near invincibility (like superman)
ifrit let the lava flow in the whole arena
agni rudra dance with fire incinerate the whole arena
here are the facts
venom is weak against fire
when using quick heart dantespeed = to venoms
when using quickheart+quicksilver dantes speed is 10x more than venoms
dante can take damage as much as venom during sparda(devil trigger mode)
dante uses fire attacks and he can surround himself with fire since VENOM IS WEAK AGAINST FIRE and the fact that Dante SURROUNDS HIMSELF WITH FIRE which gives me the conclusion that Dante will be untouchable if venom attacks. venom can hide in and camouflage himself but where is he gonna hide? since the whole battle arena is up in flames.
