sasuke has itachis eyes, yet itachi has still got them with full mangekyou abilitiesIzuna seems logical, but his eyes were removed before he died so he would be revived without eyes, since edo tensei bodies are revived as the moment before they died. (nagato, kakuzu)
So6p and his sons unlikely because kabuto said you need enough dna to summon someone, after all those hundreds of years there probably isnt enough dna. 1st hokage is probably an exception. also these would be far too powerful and overpowered.
either its a character we dont know.
I actually think its possible its the uzumaki clan leader.
