Aphelion!
The first son of the chief alchemist, Albedo and Xochitl Huitzilihuitl. He's the oldest of all their children. Aphelion is an alchemy prodigy, though he’s not at the level of his father yet. Currently, he's just an apprentice studying under him along with Sucrose and Timaeus. He has his father’s blond hair, but eyes dark as night. He's somewhat knowledgeable on shapeshifting, but he actually prefers to keep his horns.
