So many ideas, but I'll keep it brief. I keep thinking back to the fact that Orochimaru is Sannin, and even Jiraiya and Tsunade couldn't beat him. Yet most of the Akatsuki are stronger than Orochimaru. So:
Right Thumb or Right Thumb of the Akatsuki
Right Index or Right Index of the Akatsuki
Right Middle or Right Middle of the Akatsuki
Right Ring or Right Ring of the Akatsuki
Right Pinky or Right Pinky of the Akatsuki
Left Thumb or Left Thumb of the Akatsuki
I think you see where this is going. So I'll stop there. Those are some ideas. And then I was thinking, shouldn't Hokage be interchangeable with the other Kages based on where you're from? But this has probably already been discussed. I'll stop here.
