It was supposed to be a friendly challenge. It was supposed to be a photo op. It was supposed to be fun. But when Generation Ex, the Muscle League's newest team of superpowered wrestlers, challenged Kid Muscle and his friends for the right to protect the Earth from evil, things quickly got personal. Real personal.

Now Kid Muscle is the last member of his team still fighting, and three Generation Ex wrestlers stand between him and victory. There's Jaeger, master of the bloody Red Rain of Pain. Hydrazoa, the guy with the weird water powers. And the brutal Scarface, whose real name...and real agenda...remain shrouded in mystery. If the Kid can defeat this terrible trio, he'll become the galaxy's reigning champion of Good. If not, he'll be handed a one-way ticket off the planet Earth...if Generation Ex lets him leave the ring alive!
