Brian Braddock has superhuman strength, speed, stamina, durability, reflexes, senses, and the ability to fly at supersonic speeds. He possesses enhanced perceptions that allow him to be aware of things others may miss (such as objects cloaked by spells of illusion). When he and Meggan destroyed the Otherworld energy matrix at Roma's prompting, the energies that allowed him to retain his power within the UK without his costume were dissipated. Hence, to retain his powers anywhere on Earth, he must wear the costume at all times. His costume acts as an antenna and battery, allowing him to retain his powers wherever he goes.
