I read Abara once. It's a short series (13 chapters), not much plot or character development. Artwork is very unique but there's really no storytelling. You have to figure things out on your own. The last chapter was badass.
Anyway Itou Denji tanked an explosion that obliterated almost all of the planet he was standing on to bits. Also was smashing city blocks and easily hypersonic+ in speed (speed is portrayed to be visibly high for the Gaunas in the series). Doesn't really have hax last time I checked other than electricity manipulation in the last chapter.
He's pretty damn powerful, I mean, chances are that he can get up to the top tiers in the Saiyan Saga of DBZ.
Hulk would win if he's got planet level+ power + durability with some regen or hax sprinkled in there.
@phantomrant: "sprinkled in there" lol. So anyway, so you know this is what the hulk can do at any moments notice(posted pics). do you think this guy your talking about will still hold up?
You don't have to worry about what Itou Denji can do.
Just know he's going to get his shit wrecked by the Hulk.
