Helion

The spirit of the Sun is the most potent spirit in the World of Darkness. He goes by the name "Helios", and is for the most part, a benevolent spirit. His servants are known as the Helions, and while no one has ever spoken to Helios himself, several werewolves and spirits have had dealings with his incredibly powerful servants.

Helions in the Shadow
Sometimes appearing as small orbs of fire, they are no prone to appear at night. Helions have no special powers in the shadow, that people know off, apart from the ability to shape shift, and apparently, when they die, the take evering in several miles radius with them. They are very much airborne when they wish to be, and seem to have some fire or heat based powers. Only very few spirits have faced Helions and lived, and a select few, long dead werewolves have witnessed the effects of an enraged Helion and walked away to tell the tale. Helions are not known to have any regards for themselves, considering themselves to be "but rays of the sun", and have been known to sacrifice themselves to achieve great things. Only the greatest of spirits do not consider Helions to be gods among the spirits.

Helions in the Material World
If a Helion was to appear in the mortal realm, which has probably happened, but never been discovered, the spirit would like possess the body of someone, or something, and from there on out, it would basically be superman, on fire (or not, if it so desired).
