Alicia (アリシア Arishia) was the departed queen of the Gamma World.
Little is known about Alicia other than she was the wife of Adonis and the mother of their four children. Horrible! Disappearing World! She died from disease sometime after the Gamma royal family came to the Gamma World, followed by her oldest child, Argos. Opposition! Father & Daughter! Conciliation! All Resolutions! Gather! Chain of Grief!
Her death would lead the widowed Adonis to try and create a perfect world free from death, leading to the development of the Gamma's Eyecon System. Amazing! The Gamma's World!
