Solar Wing (太陽の翼 taiyō no tsubasa, lit. "wings of the sun") is an alias of Apollonius. While DEAVA used it to refer to the reincarnation of Apollonius, who was at the time thought to be either Sirius de Alisia or Apollo, the Shadow Angels used it to refer to the itself. According to them, the purpose of the Mechanical Angel is to pollinate the Tree of Life in order to rejuvenate the world and produce the next generation of Shadow Angels.
