@Low: It doesn't matter at the typical level of strength found in OP. That's the issue. If Akainu were struck by Zanka no Tachi, it would literally vaporize the magma into plasma. If Kizaru were struck with something that bends space time visibly, he would be in trouble. If Superman punched him he would die. Now i'm not saying Aizen is Superman with Kurohitsu but he has high potency. (Also there is strong evidence that he actually is Superman. See for yourself).
At the end of the day, I still see KS as being enough. Aizen draws his blade and the fight cant go any other way but this.
@Low: logia intangibility is reforming not technically regeneration because when they are actually injured, they don't heal. Only Marco does since he's a Phoenix not logia. And they are still susceptible to forces of the universe like Gravity which effects all particles including light. Kurohitsugi ftw.
Aizen can make them fight each other. He did this before when everyone thought they were fighting him and they weren't. Haki sensory at the level of bypassing KS fully is too great of an assumption. While we know everyone here has haki, there are massive differences in the level. It can't be assumed everyone is like Rayleigh or Enel without showing it, otherwise we could say Aizen who is a confirmed kidou master could use forbidden kidou like time stop ,sealing and spacial displacement which is quite possible but not proven. Also for this thread speed is equal and intangibility off.
@LoveLessNHK: Hello again. I noticed you have Kazuma in your lineup. I already had Kazuma in my team as well. We're not supposed to have repeat characters but if its troublesome to change don't worry about it. I'll swap him out if you want to use him.
@Low: Akira Manga chapter 4, volume 4, at page 360 and onwards for about 20 pages. He collapses a pocket universe previously created by Akira, as you see the buildings Akira had previously absorbed falling out of the sky. He also finds out the true power of Akira. I'll find the teleporting scans later, but they're pretty famous and easy to find.
I read that. It was incredibly vague. At the end he created a miniature big bang and Akira negated it with one of his own. Very hard to grasp just how strong Tetsuo was. The whole idea was that he was dealt with before he became literally unstoppable.
As far as on panel feats, he did take a chunk out the moon among other good feats.
