I like Elagabalus for him for some reason, though that is technically the name of a person. Some cool Greek names I'm thinking of off the top of my head for this kid are Ajax, Telemachus, Midas (pretty good with his golden sides, I think), Perseus

Some Greek god names: Hephaestus, Hermes, Cronus, Typhon, Proteus.

Roman gods: Jupiter, Janus, Saturn

Hope that helped. I do like Helios for him too. He's a beautiful boy love his sides.
