Pyrokinesis

Pyrokinesis (from the Greek words pûr and kínesis: fire moving) is the ability to manipulate and create fire and heat as well as a strong resistance to being burn by fire. Leo Valdez has this ability. He uses it to defend himself and also to protect others. Only a few chosen children of Hephaestus share this power. It is said to only appear in demigods when horrible things are destined to occur, because, as Jason puts it, that is when they are needed most.

History
In 1666, Thomas Faynor, the last pyrokinetic child of Hephaestus before Leo, accidently lost control of his fire powers in his bakery. This is what started the Great Fire of London, which was thought to have been started by one of the ovens.

The Lost Hero
Only two demigods in the series have been revealed to be able to use Pyrokinesis, Leo Valdez and Thomas Faynor. Leo at first is unwilling to tell anyone about his power because he feels that his power is a terrible thing, believing it caused his mother's death and his cabin feels that pyrokinesis is a curse (as people with this power only appear when bad things are about to happen). He does however use his powers to withstand Festus' flame attacks and used it again for breaking a chain holding an engine, causing it to fall on Ma Gasket. He later battled Khione's snow powers with his own fire and managed to drive her off.
