After one-upping themselves with a triumphant follow-up to their bestselling comic book, the Last Kids on Earth are met with unexpected competition: Skaelka has written her own comic and it's selling like hotcakes! Determined to reclaim their #1 spot, our heroes get to work to create the ultimate threequel . . .

When a vicious monster attacks Apocalyptia, a group of adorably fluffy and delightfully stinkin' cute mascot-shaped heroes arrive on the scene to help: the Laser Blade Hero Squad! Forming an alliance with our heroes, they agree to look after Apocalyptia while the Savage Aloner is called home on a mission to save his people from a mysterious threat. The entire land, and its citizens, have been . . . cutified! Now it's up to Savage and our heroes to get to the bottom of things, before Barbarious Fantastica, and the rest of Apocalyptia, becomes permanently adorable!
