[quote=@Dynamics] You can erase your save from the game files. Explain Misaka then. [/quote] Looking alike doesn't mean they're alts. Also, Ma'at used to take the form of her sister, but changed back to her own to match her long hair after getting with David. (The sister had to be added to allow for the backstory to fit with them coming back after the Yander incident.) Izaya isn't and alt of Third, for example. Dark and Seth aren't alts of Accelerator, for another. Codex are isolated existences because their base species doesn't have more than one Source where they exist. (Pre-Incident) That means there's no way for them to have alts other than Paths which are irrelevant because Source and Path entities/beings can't interact. All of this was going to be explained in Osiris' meeting in more detail to explain the Post-Incident changes, such as non-pure base species being Codex in the newest generation.
