Nubbeh
Honestly I'm really pumped up and anticipating his adventure. Wonder what he will do, who he will meet, where he will go and what will he experience. Btw he can go for the strongest body/physical strength possible by practicing 8 gates, Lightning Release Chakra Mode, Seven Heavens Breathing Method, Body Revival Technique and Tsunade's chakra enhanced strength. His own body will be scary strong then without any enhancement.
