That thing has appeared before in fake Karakura town. It tore out Matsumoto's stomach and beat Hisagi near to death until Yamamoto one shotted it.
That doesn't ring anything in my memory but I'll take your word on it.

So we can safely assume Fodder will also oneshot it in the next chapter, perhaps in an even more convincing manner that Yamamoto did, before the surprise Ichigo takedown (complete with a panel depicting Fodder being caught off-guard by Ichigo who shunpo-ed behind him).
I thought the fact this was the final act would push Kubo into going balls-out with a good rhythm...
