Are both current?
Well going based off Powers Naraku should win. Seeing has Naruku was mr.overpowered ,and magically loses due to PLOT DEVICE.
I really hate when Speed gets thrown in when there are other factors.
However, Hiei does have better speed,strength,and DC than Naraku. But Naraku has better powers that should allow him out to beat Hiei.
I'm still iffy on my statement, but I'll stick with it for now.
@Whats_out_the_bag: Speed isn't just an issue. Hiei's Dragon of the Darkness Flame, by the Three Kings arc, would be more than enough to completely wipe Naraku out. Naraku's defenses wouldn't be capable of handling it and the other powers he has on him won't be enough to protect him against the fire demon.
@Dream: I beg to differ! I do know of hiei's dragon of the darkness flame and yes it should be more than enough to kill naraku, but the thing is Naraku's capable of turning invisible Invisibility is a great feat within its self. But it doesn't matter if he can't destroy hiei ; is what you guys would say. And you would be 100% right , yet he has the jewel which in terms of power should be more than enough to handle Hiei. I won't go into detail about the jewel, but for now I'll just state some of his powers that will allow him to win.
With the joined capabilities of Flight and Invisibility Hiei would not even know where Naraku is. Now Naraku does possess multiple powers that would mind rape even Hiei him self. One being his spider webs. Many people seem to not recall Naraku's spider webs. In the begining of the series he was capable of controlling Kohaku with it, and they can be shot from the sky and have crazy long range.
@Whats_out_the_bag: Last I recall, Naraku doesn't have invisibility among his ridiculous arsenal of abilities. Flight won't matter much considering Hiei's superior speed would make it just about impossible for Naraku to land any attack and he's only used mind control to take over weaker foes.
