Obito can beat anyone

[Demonic.]

Kaguya
Naruto
Sasuke
Madara
Hashirama
Minato

These guys beat him ^^^ assuming we're not talking Juubito. Only the bold beat him then.

I'm pretty sure kamui doesn't work that way, m8.

actually it does, Obito has been shown to open portals to distant places aswell, the way he opened the acid dimension, he can simply create a portal the opens up near sun, which is very similar to how obito teleports to far off places.
