I see this fight going like this, Hollowfied ichigo speeds about the place spamming cero's and sneaking in some slashes. kenpachi is like the hulk in the sense hes all power.but ichigo is incredibly fast and strong, his slashes will bring him down eventually. and Kenpachi is never serious, like ever. but you said current kenny no? so who knows what he has up his sleeve , maybe he has a bankai now?!
Going with H2 Ichigo with high-mid or low-high diff.
The two should be as equal as you can get in physical strength/cutting power, with Kenpachi possibly having a shade more reiatsu, but H2 Ichigo's blitzing speed, regeneration + durability, and long-ranged massive Ceros edges it out for him quite nicely. Especially if H2 spams those Ceros at point blank at Kenpachi, I don't think he's going to come out without losing a limb or something.
@EraserCannon: @taichokage: @DBZ_universe: @TheNeutralOne: Can you guys explain to me how does Zaraki win? I mean we have never seen the full extent of either characters powers. Zaraki we will see later on but we have never seen Vasto Lorde Ichigo's full power. Or are you guy's just saying this because of powerscaling?
@AnimeDefender: She is one of the first Captains, she like Kyoraku are crazy powerful. Kyoraku should be above Vasto Lorde specially since it was said that his Bankai>Aizen.
Also Yamamoto did not want to teach the Arts Of Kill to Kenpachi for a reason right?
@DBZ_universe: Like I said, no one knew of this Vasto Lorde form for maybe the exception of Zangestu ( which technically it was him ). True, Yamamoto did not want to teach the Arts of Kill to Kenpachi ( which he already knew... the bloody parts...... ). But again to my first point, no one except maybe for Zangestsu knew about it. We don't know how truly powerful Vasto Lorde form truly is. Though I will admit, this is a assumption of my part, believing that Vasto can be a lot more powerful than current Kenny.
