Steelheart is a mechanic and strong member of the SilverHawks along with her twin brother Steelwill.
Sergeant Emily Hart is Will Hart's twin sister. They are the "scientists" and "gearheads" of the team. They share an empathic bond in that when one sibling feels something, the other feels it as well. They are the only SilverHawks who have had real stainless steel hearts implanted during their transformation. She and her brother were the ones who created the four Fighting Hawks. Her weapon-bird is Rayzor.
Steelheart is a SilverHawk, a human law enforcement officer modified into a cyborg to withstand the effects of hyper travel through space. This grants her enhanced physical abilities, such as strength, agility, and speed. She has a hawk like face plate that covers her face while flying or fighting, as well as built in wings for atmospheric and space flying/gliding. She has a built in laser in her arm, which is frequently activated from the back of her shoulder, for combat and retractable talons in her feet for attacking while flying. She is the second strongest SilverHawk, outmatched only by her brother, allow them to be the only members of the team that can out wrestle Mumbo Jumbo. The SilverHawk procedure also enhanced her psychic bond with her brother, enabling her to psychically communicate with her brother Steelwill even in vast distances from each other. Within close distances, they can also combine their will to give themselves a power boost. Likewise, this bond is mimicked with their Weapon-Birds, Rayzor and Stronghold.
Steelheart is very intelligent and level headed. She always know how to get herself out of danger. Her technical skills are also higly valuable in keeping the SilverHawk's technology ahead of the mob.
