Here’s a sweet reprint from Marvel Collector’s Item Classics #5, originally published in The Incredible Hulk #4. Stan Lee and Jack Kirby got the Hulk fighting aliens early in the series. This was back when Bruce Banner turned into the Hulk at sunset, so he hid out in a cave all night. There he kept a gadget with a footswitch that would radiate him on demand. That was just in case he needed to Hulk Out to save the Earth all of a sudden! Okay, enough reminiscing — let’s meet: MONGU! The Gladiator from Outer Space!
