Superman #209

Superman #209 (On Sale: June 20, 1968) has a cover by Ross Andru and Mike Esposito.

Inside we have "The Clark Kent Monster" by Cary Bates, Curt Swan and Jack Abel. When an alien brain creature comes to Earth it attacks Superman with deadly mento-bursts. The blasts are powerful, but they are deflected off Superman's invulnerable body and back at the creature. The creature is destroyed, but it is able to connect with some of Superman's brain cells and reform in the identity of Clark Kent.

The alien Clark heads for the Daily Planet and displays uncharacteristic self-confidence. He single-handedly defeats the Marauder Mob with new powers. As his power increased, he becomes a menace.

The back-up is "The Super-Servant of Crime" a reprint from Superman #130 by Robert Bernstein, Curt Swan and John Sikela. Superman needs to raise money for charity so he burrows into a gold vein and takes the gold. The owner of the land, a criminal named Mulloy, claims Superman is stealing the gold. Superman makes an agreement with Mulloy to perform super tasks for Mulloy.

Mulloy makes several requests of Superman, but each time Superman brings him something of little value. For his final request, Mulloy asks Superman not to capture him. Superman agrees, and the caretaker of the land, Baldy, knocks Mulloy out and takes him to the authorities.
