@taichokage: I don't see how Komamura can't one-shot, I have seen nothing that puts Kenpachi's pre-released patch state above Komamura's bankai power. Kenpachi was halted by a technique that was simply said to be stronger than steel (Something he dealt with when he fought Nnoitora, of course it was not going to work) Not to mention with Gremmy's imagination it was not hard to picture stopping a normal looking blade like that. However with Komamura seeing a gigantic blade coming down on your head will be a bit harder to picture stopping with your body. I dunno about healing himself since Gremmy did that only after Kenpachi opened his mouth, he was bleeding out from those few slashes, Komamura could arguably cut him in half on the first swing. Gremmy will become disastrous after all his attacks fail on Komamura, the only thing he needs to worry about is BFR but Zaraki himself simply pulled himself out of it and even resisted going in there for a bit, I'm pretty sure something of Komamura's bankai size can put up a bit of resistance or pull him out if needed, also that thing was not even big enough to fit all og Komamura and his bankai in and it still costed a lot of energy to do. I see Gremmy going down before he even gets that far, Komamura just walks through everything he does causing Gremmy to panic since unlike Kenpachi who destroyed a majority of Gremmy attacks, Komamura will be completely unfazed. I doubt Gremmy will be able to concentrate on his own durability when dropping meteors and Komamura just cuts him right through the meteor aftermath. And Komamura has a whole 20 minuets of complete invincibility, Gremmy has not shown to be able to fight for that long after using his techniques and he is not gonna be able to outrun Komamura, not to mention he has not understanding of how Dangai Komamura works making it even worse, this wont be too much different from Kenpachi's fight honestly.
He has the power to imagine anything (not proven) and bring it to life. He's a reality warper.
This is his best feat.
@DBZ_universe: Gremmy could do nothing to harm Kenpachi and he wont be able to do anything to Komamura. Lol, Komamura blew her up all the way across the Soul Society, she was pretty much dead until her sisters came to help her, he was only taken out by his time limit. That girl one-shotted shinji, a senior captain and visord. Bambi would destroy pre-training Knepachi and arguably be able to blow him up post training, does Knepachi have any defense against being tunred into a bomb? Because Gremmy's self destruct did some damage to him and Bambi's bombs should be far more potent and lethal. Nevertheless Gremmy can't last 30 minuets nor has anytihng to put Komamura down.
@Saladking: Basically a low tier reality warper, can create meteors at will, turn people's bones into cookies, open up a small portal to space, and imagine himself completely healed if he is close to dying.
