Alchemy Stars (アルケミー・スターズ Arukemī sutāzu) is an organization in Ultraman Gaia. A British organization founded back in the 1980s, Alchemy Stars was a scientist based network composed of child prodigies from around the globe.

Due to this, GUARD was formed along with it's branch, XIG. Their technologies such as the Aerial Base and the XIG Fighters along with the anti-gravity hover tech, Repulsorlifts were developed by the Alchemy Stars.
