The Arsonist

Hestia Jones was formerly a Soltech scientist researching the pyrokinetic abilities of Cobalt Red. After she was fired from her job in 2019, due to receiving repeated complaints from her co-workers, she stole copies of her research and retreated into an abandoned factory in the Ironworks, taking it over as she continued her research. In 2021 she emerged having mastered pyrokinetic technology based on Cobalt Red's abilities, and began to use it as the Arsonist.

As the Arsonist, she tracked down her former coworkers and set the buildings they were in ablaze, burning them from the outside in to try to trap her target. She would have robotic drones outfitted with the same pyrokinetic tech set the fires for her, while she herself sat back and watched. She would join in battle when it begins, but typically flee through a fiery teleportation effect when things turned against her.

While all the pyrokinetic aspects of the Arsonist and her drones are hypertech and ultimately based on Cobalt Red's powers, she does have a power of her own - an immunity to heat and the ability to precisely detect and map out thermal energy around her.

She was captured in December 2021 by a group of heroes including Phoenix, Magnet Maiden, Shirai Kage, Iridescent, and Signal, and is currently held in the low-security wing of Iron Depths.
