As Gremmy and Kenpachi continue to trade blows, they are finally forced to show their stronger hands in battle. Kenpachi attacks so quickly that his opponent is unable to react quickly enough to block and heal off the hits, and for a moment Gremmy considers the possibility of defeat – one that his own imagination makes all too real. He quickly comes back to his senses though, and unleashes what he calls his ultimate power. This is a phrase we’ve grown tired of hearing, but his power doesn’t seem particularly remarkable. As he did before with the creation of Gwenhael, Gremmy now creates another copy of himself, complete with all the same abilities that he already had. His technique raises an awful lot of questions, like if he could create infinitely many copies of himself. After all, each copy increases his power of imagination by one, thus theoretically allowing each of them to recursively execute this ability. Each copy is able to think independently and is exactly the same as the original; even Kenpachi could not defeat an unending number of Gremmy’s. That said, his first action after creating the duplicate is to summon a giant meteorite. This certainly doesn’t require two minds to imagine: he is now able to keep track of multiple imaginations at once, but a dual-core CPU has no effect on simply thinking of bigger things.
In addition, why couldn’t he had done this in the first place to end the war before it even started? After all, Yhwach just needs people to die in order to maintain his own power; a protracted war doesn’t accomplish anything more than having one of his subordinates nuke Seireitei out of existence before they even figure out what’s going on. Of course, this is what would make sense given the characters’ logic and goals, but in reality I doubt his meteorite could actually destroy everything. Remember that at this point in the series, characters can essentially level mountains with every blow. Regardless, it is evidently powerful enough to finally make Kenpachi draw his shikai – Nozarashi. Whatever this does, I guarantee that the Gremmy’s and their meteorite will stand no chance against him.
