Wow, so we finally get to see Grimmjow alive again. But there's one other individual that I've been wondering about for years. Remember the last surviving Bount, "Gō Koga"? After Ichigo defeats Kariya, Koga asks Yoruichi to thank Ichigo for stopping Kariya for him. But as far as I know, that's the very last we see of him. Will Koga ever make another appearance again?

Arrancars are a mix of soul reapers and hollows with the power of the hōgyoku, but was Aizen ever even aware of the existence of bounts and their powers?
