Space Ghost is a highly trained Peacekeeper. He has had extensive training in weapon use and hand-to-hand combat. He also has advanced alien technology, including his power bands that gives him an edge over those that oppose him. The power bands each have three buttons. Using them in different combinations, Space Ghost is able to deploy different types of blast power. The bands are capable of emitting stun rays, heat rays, freeze rays, and can even produce a force field to protect him. Space Ghost also has an Inviso-Belt that members of the Wraith had used. When using the Inviso-Belt, he is able to phase through walls and objects
Nova derives his powers from a source known as the Nova Force, which is wielded by all members of the Nova Corps. Nova's small share of the Nova Force gives him abilities that include flight, super strength, speed, and durability, as well as the power to absorb energies directed at him and release it as gravimetric beams and pulses, either from single parts of his body or from his entire body surface.
