it's exactly this, I don't want people to say that Smallville's Supergirl is a doppelganger of Indigo since they are technically two different species but Smallville's supergirl could be put in the Multiverse Counterpart page with earth-38 supergirl but should not be considered as doppelganger since they are not the same version of a character but two characters that looks the same.
