"The Power That Failed!" Part 1 of 2. For some inexplicable reason Superman's powers - strength, flight, speed, invulnerability, and vision - begin to fail him. How can the Man of Steel hope to survive an all out attack by the new menacing duo of Psi-Phon and the hulking Dreadnaught? Meanwhile, a strange new visitor who bares a striking resemblance to a fallen heroine, makes her way toward Smallville. Plus, Lex Luthor gets a new hand (his hand was amputated due to Kryptonite radiation poisoning - see Action Comics #600).

Notes:

• Story continues in Adventures of Superman #442.
• First appearances of Professor Thaddeus Killgrave, Dreadnaught and Psi-Phon.
