Helen Bennett, aka Mother-1, is Jack Bennett's wife. She is an oceanographer and an accomplished marine biologist. Mother-1 possesses various ESP powers that allow her to occasionally see glimpses of the future, telepathically communicate with other sentient and non-sentient beings, determine the function and operation of mechanical devices by mentally "tracing" their internal workings, and can mentally project hologram-like optical illusions. She is also an accomplished fighter, having bested Dr. Scarab's henchwoman Madame-O on the occasions when the two physically fought each other one-on-one.
