Warren is the only character that demonstrated this ability. He showed various aspects of this ability including creating extreme heat in his hands to burn others, without flames, lighting his hands on fire while holding someone, as to harm them, coating his entire arms in flames, creating fire balls, and shooting blasts of fire from his hands. Warren was only able to create fire from his hands and could extend the fire to his arms. It is unknown if he could create fire from the rest of his body or extend the fire to any other parts of his body. If he could, he may be able to coat his entire body in flames.
