Why was Madara resurrected young when the wiki states that the person is resurrected to the appearance of them during their death?

Maybe it's because Kabuto used the clone that Madara had put in his coffin. So therefore, the Madara everyone was fighting was just a clone and not the real deal. Bro i'm such a genius.

Kabuto mentioned that he applied selective evolution to Madara's body. To make him even better than what he was in his prime. So it's largely Kabuto's doing that his edo tensei form is so young.

Though @Sy6up, your interpretation is intriguing.

I do love how when Kabuto states that he made him better than he was in his prime, he looks offended. Implying that Prime Madara was far stronger.

Funny to think that even at that point, Madara still knew the limitations of the edo tensei and how he needed to be alive to access his true power.

Because this is the way edo tensei works (Pay Atention to SPOILERS should you have not finished the anime yet): the person can be restores to the original appereance at the time they died, even lost madara`s lost eyes could be restored by kabuto, thou not at full power like the original dojutdu were, once Edo as dismissed madara retuned to the actual age he would have if he was to be still alive somehow, and his eyes disappear as well (since he removed and implanted them in Nagato before dying) having to re implant his right rinnegan and taking kakashis sharingan for his left eye. about sakumo there is no certain way to determine at which age he died he "looking older " may be just an impression of yours or an kishimoto`s oversight.

I’m pretty sure Madara was revived young because kabuto said he made adjustments to Madara body and did more than just giving him hashirama cells
