Naruto Thread (Spoilers For Sure)

See the thing is, Tobi has those marks under his eyes the same that Madara has, but Madara's brother doesn't have those. Maybe they are just old age lines but I doubt it.

Tobi's body definitely has some Zetsu material, he's lost his arm twice.

So hard. Gotta be his younger brother though. Maybe he did split himself somehow...
