Sin is trained in various forms of physical combat and highly proficient with various weapons. As Mother Superior, she was given powers and technology to administer painful mind blast, walk on air and through walls, put victims to sleep or read their minds with a touch, teleport, move objects with a gesture, and create force fields. She was also able to impart some of these abilities to others. Her powers apparently disappeared when she was de-aged. She was an adept brain-washer, sometimes using the Skulls Deus Machina, which created realities out of "mindstuff."
