Does someone need to be a reincarnation of Indra to get the EMS? I'm asking this question because I think it is crazy that the only people who ever got the EMS in Naruto series are reincarnations of Indra.
Does someone need to be a reincarnation of Indra to be able to get the EMS?
No, you do not need to be a reincarnation of Indra to get EMS (Eternal Mangekyo Sharingan). To obtain EMS you must take the eyes of another Mangekyo Sharingan user, but they must be family, most commonly a brother. Examples would be Sasuke taking Itachi's Mangekyo Sharingan, or Madara taking Izuna's Mangekyo Sharingan. You have been confused because Madara and Sasuke are the only people in the Naruto-verse to have EMS, and they are reincarnates. Itachi's &quot;Goal&quot; was to obtain EMS from taking Sasuke's eyes (He is not a reincarnate).
