Yumichika is gonna win this fight. If I remember correctly, he's only 3rd seat under Ikkaku because he didn't like the number 2 or something like that right? It wasn't beautiful enough for him. Using that logic, if Ikkaku is "weaker" then Yumichika should/COULD have a bankai as well. But he would NEVER use it....unless ikkaku was dead....

Now what could the giant soul sucking plant be as a bankai, a bigger gianter souler suckingest plantier type thing. Or something like that. Anyway, I think the bankai will be able to absorb enough energy to revive one or two, or tons, of people. I suspect it'll be a way for Kubo to ret-con some negative feedback. And I think it'd be a great concept of giving life from the dead (zombie) in the whole circle of life thing.

All this assumes one thing....Yumichika is stronger than Ikkaku...which might not be correct.
