Helios (Sol)'s Clique: Pyros
You know how you were told when you were little to never play with matches? Well, Helios and his flame-loving friends just never got the message. They like nothing better than to watch something burn. Setting trash cans on fire, throwing M-80s into toilets, setting off fireworks in the auditorium... you name it. If it has to do with fire or explosions, these kids have given it a shot.
Hephaestus
Hephaestus is the Greek god of fire, volcanoes, and blacksmithing. One time, he got seriously bad news from Helios, when the sun god told Hephaestus that his wife, Aphrodite, was cheating on him with Ares, god of war. It was hard for Helios to break it to him, but pyros have to stick together, right?
Hestia
This virginal goddess was the goddess of the hearth, and likes nothing better than knitting with her feet up by a crackling fire. She was also the goddess of the sacrificial flame. So every time an offering was burnt in sacrifice to any god, Hestia got a piece. Hestia was one of the original twelve Olympians, but gave up her seat willingly when Dionysus came along.
Pele
The big mama of Hawaiian goddesses, the mistress of volcanoes is said to live in Halemaumau crater, which is still fiery and smoking to this day. Rumor has it that every eruption on Hawaii's Big Island is an expression of Pele's longing for her lost love, Lohiau.
Loki
Loki, with his flaming red hair, is a Norse fire god. Other than that, he's not a whole lot like Helios. Oh! In the Avengers movie, the Hulk totally kicks his butt, and it's hilarious.
Ika-Zuchi-no-Kami
This fiery Japanese Shinto demon loves to cause earthquakes and volcanic eruptions. For this reason, no one ever wants to hang out with him on the weekends.
