Naruto wasn't so bad, but if Obito can fully controll his newfound powers I'm seriously disappointed.

Every other Jinjuuriki needed years or even decades to master their bijuu and even then most get overwhelmed sooner or later, except for bee and the other hidden cloud one, since both of them managed to befriend their bijuu.

But Obito didn't just get a regular bijuu, but a being that combines all the bijuu's power and malevolence and he's barely alive to boot. There should be no way in hell for him to use even the tiniest fraction of the jubi's power right now.

As for Bleach: How could it be Grimmjow? He'd have died from Ichigo's wounds alone, but then got sliced apart by Espada #5 (forgot the name, the one who cracked Neliels mask). I think it might be one (or several) of the surviving Fullbringers Jackie, Riruka, Yukio and/or Moe or Nel with her companions. I'm hoping for the latter. While her fraccion is rather annoying Nel herself is great, both in the child and Neliel forms.
