he was brought back with the animation wrong to because it said that when you die you are re-animated just like that look at nagato and his hair for example when madara died he had one sharigan eye but plot some how managed to bring him back wit 2 rinnegan when he only had one eye when he died think back too when he left it all too obito and unplugged from the gado mazou and then when he got brong back to life no eyes and still dodging attacks I don't understand
Edo Tensei is a space/time jutsu that contradicts reality. Kabuto didn't elaborately explain it, but the specific incantation of the jutsu combined with Madara's DNA, which manifested Rinnegan at some time allowed him to bring Madara back in his prime. Madara resurrected without his eyes because he was real flesh and blood again and left his real eyes preserved in the living world with Nagato.
He resurrecting without the base sharingans he took from someone is likely explained by he being resurrected young rather than old when he implanted them into himself. Furthermore, they weren't part of his DNA, they were someone else's eyes.
