An average-sized man, measuring approximately 170 cm (5.58 ft) tall and slightly muscular—though he, too, can take on any form he desires. His skin, which shifts through shades of green depending on his emotions, turns absolute black when his fury completely overtakes his consciousness; this draws all the color to his outline and begins to scorch the air around him. Meanwhile, the stars within his veins shine brighter than ever, leaving streaks across his body.
He harbors a great power—capable of creating and recreating at his whim—but he limits himself to mere observation, unwilling to misuse it. He has always upheld a policy of non-intervention in the lives of those he is meant to care for. He has made few personal appearances, preferring instead to send Iris in his place—since she is less experienced and has a less intimidating appearance. He cares deeply for his sister and is always willing to do anything for her.
He lives in the void of chrono-space, where space and time continuously expand. It was there that he ended up alongside Iris after accepting their destinies as gods of a world to which they no longer belong. Melancholically, Orion recalls those days spent with Iris in their home—caring for her and wrestling with mundane worries; spending time with his other friends, of whom nothing remains but mere memories. There is not a moment when Orion does not feel guilty about how things ended, and without having Iris under his care, he probably couldn’t bear the weight on his conscience.
