Billy Blaze was more than just an average eight year old boy. He was a hero on – quite literally – a stellar scale. As Commander Keen he protected not just the Earth, but the whole galaxy from danger. He thwarted the Vorticon invasion and freed the Vorticons from slavery at the hands of his arch nemesis and classmate, Mortimer McMire. He stopped the vicious Shikadi from destroying the galaxy. Keen even saved his babysitter, Molly McMire from the hostile planet of Fribbulus Xax where she was almost eaten by carnivorous Bloogs.

And then... nothing.

His arch nemesis disappeared. There were no more impending invasions to thwart. No more galactic danger. No more babysitters being kidnapped by hungry aliens. The adventures of Commander Keen became a memory. Billy grew up.

Seven years later. Billy Blaze is living a normal life like a normal teenager. He’s made new discoveries and didn’t have to travel halfway across the galaxy to make them. Sci-Fi conventions. Science fairs. Video games. Comic books... girls.

Billy has plenty to keep him busy in ‘normal’ life. Should he really be concerned about the fate of the universe too?

When his nemesis returns with plans of destruction on a universal scale, and in their battle Billy ends up stranded on an uncharted planet, the answer to that question seems to be an astounding ‘yes.’

A Commander Keen / MLP: Friendship is Magic crossover.
