Artemis has a secret. He isn't actually from the My Hero Origins dimension. He's actually from the Origins of Olympus dimension. He's the son of Bryan(son of Aphrodite) and Inpu(son of Anubis). After Bryan's death, Inpu sent Artemis to the My Hero Origins dimension so he could be raised properly. Artemis isn't even aware of any of this. Well... until later today, that is.
