- Pyrokinesis: Sun Girl has the ability to mentally control the ambient heat energy within her immediate environment. She can reduce objects' temperatures, raise them to several hundred degrees, or extinguish open flames. The heat energy she takes from the environment is absorbed into her own body.
- Flight: Sun Girl is able to manipulate hydron atoms to produce a hot cloud provides sufficient positive buoyancy for her to float. With mental stimulation of her flame, she can provide enough lift propel her body. By forming a jet from her feet, directed behind her, she can accelerate up to supersonic speeds.
- Energy Resistance: Sun Girl is unaffected by heat and flames, including her own, even when part of her is aflame and the rest of her is not.
- Vulnerability to Extinguish: Sun Girl's flame is supported by the presence of oxygen, and thus is extinguished in low air pressure or a vacuum. Sun Girl's flame can be extinguished by smothering materials, such as water, sand, fire-fighting foam, and heat-resistant blankets.
- Her real name and super-villain name suggest a connection with Dirk Morgna, aka Sun Boy of the Legion of Super-Heroes.
