Fire Elemental

Fire Elementals are a kind of supernatural being, presumably a species of demon, who possess pyrokinetic powers: the ability to generate and manipulate fire.

Beck was a human girl who bonded with a Fire Elemental during childhood, granting her dangerous pyrokinetic abilities which she couldn't control. She killed her family with these powers, leaving her severely traumatised into adulthood.

In the prison-like environment of the Mosaic Wellness Center, pure Fire Elementals would socialise with Strang Demons because they shared a red skin tone.
