when i look back the Manga,in the early kabuto already have madara's DNA, that's why he looks young when been revived.
what we saw madara now is a old man.i don't think kabuto took his DNA when he is death. possible?:shrug:
"in the early"
"kabuto already have madara's DNA"
"looks young when been revived."
"when he is death"
0_o ... not sure if caveman or ...
Anyway, Kabuto specially made the Madara Edo. I don't think he could have gotten young Madara's DNA since he wasn't alive when Madara was like that ...
