"They call me Maximum Boy. It's a stupid name, I know, but they started calling me that in the newspapers. And now it's on my costume, so I'm stuck with it..." It's a bird! It's a plane! It's... it's... a UFO shaped like a barn? Yes, the Unidentified Flying Object has been recognized as an Identified Flying Barn, and Houston, we have a problem. The UFO's barn door is opening to reveal - what else? Alien cows! The bovine creatures are threatening menacing - and they take the expression "Got milk?" awfully seriously. Clearly, this is not a job for just any superhero. It must be handled by the hero who is tough, strong, has healthy teeth and a great smile. The superhero who is always on the moooove. The invasion from the planet of the cows is a job for none other than... Maximum Boy!
