Originally, Captain Britain's powers were linked to the mystical Amulet of Right, worn around his neck. When Brian Braddock rubbed the amulet he was transformed from an ordinary mortal into a superhero version of himself, complete with a more muscular physique. The amulet could also mystically replenish his superhuman energies. He possessed a telescoping staff to vault which had other functions, the most heavily relied upon being the ability to project a force field. Later, Merlyn changed the staff into the mace-like Star Sceptre, which Captain Britain could utilize like a quarterstaff and which gave him the ability of flight. Merlyn changed his costume just before he entered the alternate Earth-238, fusing the powers of the Amulet and the Scepter into the new uniform and then later put these powers within Captain Britain himself when he was forced to rebuild Captain Britain following Captain Britain's death at the hands of the Fury, making the suit a regulatory device for his powers. Eventually, Captain Britain no longer required even the battle-suit for the full use of his powers, as his heritage of being the son of a denizen of the extra-dimensional Otherworld became enough to power him.
