Dude we moved past that. Yama lost to Aizen just like everyone else. You can't get around that. So why not stop trying?
I just get sick of constant comparisons to DBZ, ODA and Naruto. I don't think you using Itachi's ability to explain Aizen works. Or at least it doesn't for me. Because basically you're saying Kishi created a better ability than Kubo. Something I don't wanna hear
P S.I used that because Yama is just some old dude with flame thrower. I actually consider his taijustu and strength more impressive than his Zanpakuto. Fire just burns things and you can put it out. Plus he still couldn't beat Aizen so yeah he doesn't impress me much...
Now how bout those fullbringers eh?
