Chroma (クロマ, Kuroma) was a highly advanced, cutting-edge synthetic cyborg which was designed and developed for medical purposes, with the hopes of lending people born with physical disabilities function in parts of their body which previously hand none. After developing its own malevolent will, chroma began to see all human life as defective, and launched a campaign to imbue pieces of itself within all members of the human race, subsequently overwhelming their proper reasoning and transforming them into his slaves.
