"Ah... an end, a beginning. Around we go." ― Echo to Rei
Echo is a part of Rei that was split from her by the Starseed upon its first activation inside of the Ultravoid. Echo appears to dwell in a surreal, vast, solid but rolling sea of red. It almost appears to be a plain or moving hills. Small droplets of red ocassionally shoot from the surface into mid-air only to disappear again.
Echo appears as a white giant, with arms that are cut so that only parts of them remain, and a torso whose chest is pierced by a massive, long, golden blade. She drips purple blood.
