Synopsis:
An alien force has landed on Earth. The army wishes to attack, but Superboy convinces them to let him try and talk with them. The aliens have indeed come to invade Earth, but are amazed by Superboy’s abilities. They decide to duel him to determine Earth’s fate.

The aliens use their super weapons against different targets on Earth. Superboy uses his powers to defeat each weapon, proving himself superior. The final challenge is for Superboy to penetrate the hull of their ship. Superboy pretends not to be able to break it, so the duel ends in a draw. With their honor and ship still intact, the aliens leave Earth forever.
