Arrival of Fuse
When Worlds Collide
When Dexter is readying his Electro-Plus Cannon to fire at Planet Fusion, a swarm of flying Fusion Spawns attacks his helicarrier. Numbuh Two, Numbuh Five, Mac, Dee Dee, Ben (as Four Arms), Bloo, Blossom, and Bubbles try to hold off the threat until Dexter completes his cannon. While this is going on Coop and Jamie are playing a video game. Jamie asks Coop if he hears anything, and Coop replies that he only heard Jamie crying like a little girl after he beat him in "Destructo Challenge."
Coop does not appear in the future. It is possible that in the future he went into hiding due to his lazy nature.
When Fuse's invasion began, it's clear that Megas was involved, piloted by none other than Coop; however, Fuse overpowered Megas and it is now left trapped inside of the Goat's Junkyard infected zone, unable to move. Coop can be found outside the infected zone at Goat's Junkyard and his missions involve things dealing with trying to get Megas free. However, he is still as lazy as in the series (he seems to be serious though when dealing with matters of Fusions and Fuse). Coop's Fusion gives out the Megas Nano when defeated and later returns as the head of Fuse's plan to mass produce Fusions.
- What happened to Jamie and Kiva is unknown, but it is probable that Fuse had some involvement. (Note, however, that Jamie was in the manga with Coop.)
- Megas is a serious threat to Fuse due to its size, strength, and general action in its eponymous show. The purpose of Megas in the show is to hold off advancing alien armies; thus it would be perfectly suited to fend off the threat of Fuse. Along with a few other heroes who have directly fought off alien invasions in their respective shows, if he had been able to prevent Megas from being overtaken by the fusion matter, Coop probably could have assisted the other heroes (or even single-handedly) to defeat Fuse long before the official war began.
