Imagine how OP Obito would be if his Sharingan evolved to Rinnengan

[Rikudou Tobi]

I know weird, Nagato who is full Uzumaki can use 2 Rinnengan, while Obito who is Uchiha and Senju DNA can't handle 2 Rinnengan.

Confirmed. Nagato's dna = Not too useless to use two rinnegans

 

[Flawž]

Obito At full power with no restrictions can be considered top 1-2. He's too beast.
