Firestar is based off of a Marvel superhero of the same name. Her design comes from the 1980's tv show Spiderman and His Amazing Friends, which she was created as an original character for. Her secret identity is Angelica Jones. Firestar is a mutant whose body stores ambient electromagnetic energy, which she can project and manipulate for various effects. As she alters the electromagnetic wavelengths, they form a microwave aura around her body, at which point she mentally "pushes" the microwaves away from herself. Doing this allows her to release heat, light and radiation into her environment at various intensities. By focusing microwaves on a specific target, she can cause it to burst into flames, explode or melt. She can project microwave energy blasts which have a thermo-concussive effect, heating objects to the point of melting or being incinerated, while the superheated and pressurized air created by the directed microwaves produces impact. Firestar can also sense microwave signals (such as cellular phone signals or remote-control devices) and disrupt electronics with her own microwave emissions. By superheating the air around her, Firestar can generate enough upward thrust to fly at high speeds and lift heavy objects.
Firestorm was my first charrie. He is based off of a DC superhero of the same name. His design comes from the 1980's tv show Super Friends: The Legendary Super Powers Show. Firestorm secret identity is rather unique, as he is two people in one, those being Ronnie Raymond and Martin Stein. While others have come and gone as Firestorm, the original pair behind him is all I care about. His superpowers include the ability to rearrange the atomic and subatomic structure of inorganic matter, rearranging subatomic particles to create objects of different atomic characteristics of equal mass. He can not only change and transmute the atomic composition of an object (e.g., transmuting lead into gold of equal mass) but he can also change its shape. He also demonstrated the ability to fly at fantastic (but unmeasured) speeds, to render himself intangible and thereby pass through solid objects harmlessly, to generate destructive and concussive blasts of fusion energy from his hands, to absorb radiation harmlessly, and superhuman levels of strength and resistance to injury.
Firestorm has two sons with Sara (#26334)'s character Color. They are Colorstorm, owned by Sib (#32471) and Color Flames, owned by Sara. Colorstorm and Glitter (also owned by Sara) have a foal called Glitter Storm, which was used as All The Pretty Colored Ponies mascot until it closed. Glitter Storm is now owned by Cheriton Arabians (#38523). Colorstorm also has a foal with Pippin, who is owned by Kostoryz (#38159), which as far as I know, never received a name
