Story
Somewhere deep in a dark limbo, a butterfly beastwoman named Bloom has resurrected a large number of villains previously defeated by the heroes throughout time. Soon, they made contact with the alien planet Bion, and created Megadrones in order to completely liberate the entire world, so that the villains will have free access to conquer it. Little do they know that the plan they conjured would unleash an even greater threat...

Now it's up to the Garage Kids and other heroes in order to put a stop to this evil before it is too late...

 * Asterius: A falcon beastman who is the guardian of space. He was also Chronos' apprentice, disappearing after a dispute with his master and joining Bloom on her mission for conquest.
 * Bloom Insectos: A butterfly beastwoman who was the former childhood friend of Thunder. She is the descendant of the Chrono Tribe, a tribe of beastmen known to travel through time. Her spirit was then sacrificed on a young butterfly girl, which is Bloom. As she grew older, the Time Witch's powers also developed, making Bloom a full-fledged successor. She used these powers to recreate the events of the past, but she knew little of the consequences that follow. Already lusted by the powers to reshape the world, she opens up a series of time rifts that brought back every villain defeated by the heroes, forming her new group of villains to conquer the world alongside the Megadrones.

Final Boss

 * Crimson: a grotesque creature formed from the technology of the Bions, designed to assist Bloom in creating the Chrono World. It is designed to create ginormous shockwaves that turn the beastmen into alien clones of themselves. After it once defeated the heroes, Bloom decided to fuse with Crimson in order to become True Insectos. But thanks to the strength of the heroes, Bloom sees her mistake and attempts to revert everything to normal.
