Pyrokinesis is a powerful ability to have. The user with this ability have the power to mentally and/or physically summon, control and manipulate fire, the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products, flame being the visible portion of the fire. Users with this ability excite the atoms within an object, with enough energy to ignite the object. A pyrokinetic is a person capable of generating flames from thin air, not requiring the consumption of oxygen or combustible objects to maintain the flames. They have been seen being able to increase the temperature in their proximity, create flames, and endure extreme heat and flame without being harmed. It seems to be an very rare ability possessed by the few chosen children of Hephaestus, and his Roman counterpart, Vulcan. Users can telekinetically control and manipulate any fire or flame, even ones one did not manufacture, and utilize them in any way imaginable. More powerful and experienced users possess complete and precise control over their shape, size, intensity, density, temperature, and even color; they could alter its size and intensity from a mere candlestick flame to an immeasurable inferno. They could telekinetically manipulate any fire or flame to do whatever they desire. The user can burn almost anything; they can heat up parts of objects or bodies or the whole object itself, leaving only a pile of ashes.

In 1666, Thomas Faynor, the last pyrokinetic child of Hephaestus before Leo, accidentally 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.
Despite being the titan of light, Hyperion is able to absorb Greek fire into his body after being hit with it.
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 seemingly only appear when bad things are about to happen. When Leo was a baby, Tía Callida puts him in a blazing fire pit of which using pyrokinesis, he withstands the flames. Later, when Leo was five, he seared his hand print an inch deep in the solid wood of a picnic table. At age eight, Leo used pyrokinesis again and accidentally burns down the warehouse his mother worked in with her inside. At Camp Half-Blood, Leo use his powers to withstand Festus' flame attacks. During the battle with the cyclops in a warehouse, Leo uses it again to endure a firestorm caused by red hot coals and kerosene caused by Ma Gasket. He also uses pyrokinesis to summon a white hot bolt of flames 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.
In the Empty, Zane Obispo discovers that the power of fire has been passed down to him by his father, Hurakan. He tells Zane to draw in energy from the sun, but he nearly burns up before a wave cools him down. His father tells him to release the energy or he will burn from the inside out. Zane later unleashes a wave of fire while defeating Ah-Puch.

- Interestingly, Thomas Faynor, unlike most children of Hephaestus, owned a bakery instead of doing anything involving mechanics. Leo has also shown to be a good cook from years of fending for himself.
- Children of Hecate have limited pyrokinesis, but only through one known spell--Incantare: Templum Incendere, as demonstrated by Lamia.
- The first ever naming of the fire-manipulation ability to be "pyrokinesis" is in Stephen King book', Firestarter.
- Curiously, the plot of the protagonist Charlie McGee, a girl with pyrokinesis who heritaged this ability from her parents, is very similiar to that of Leo, being both "firestarters". Also, Charlie having being created upon believing that her fire-ability is a bad thing as Leo did.
