One day, the "ultra-high-tech-indestructible-super-space-cyber-suit" accidentally fell on earth. Jim took refuge in the mysterious suit which caused him to grow and evolve at a fantastic rate. Now Jim must make it to the kidnapped Princess What's-Her-Name and stay clear of Psy-Crow, the intergalactic bounty hunter, until the final battle with Queen Slug-For-A-Butt.
