Orion is the second son of Darkseid and as a child he was traded for Scott Free in a peace effort between New Genesis and Apokolips. Raised as the son of Highfather he was taught to control his rage and anger, becoming the most powerful warrior either world has ever known. This in itself was not an easy task given that his heritage boiled with the rage of the brutal and merciless Darkseid. It is very possible learning how to control his dark nature consumed much of his youth. When Darkseid set his sights on Earth, Orion came to Superman's aid in defending the planet. Later, after the formation of the Justice League, he joined forces with Superman once again when his father endangered New Genesis. After the Thanagarian invasion, Orion became a member of the Justice League. He was briefly seen in the battle against AMAZO. He later played a more active role when Flash was beset by his old enemies, and was last seen fighting alongside the rest of the League in the final battle with Darkseid's forces.
