I had this idea for a series taking place in the Cartoon Network Universe. (WARNING, THIS IS ONLY A ROUGH DRAFT: PREPARE FOR CRINGY THINGS)
It takes place after the events of Fusion Fall (that MMO game that existed for a short period of time.) after the alien force known as the Fusion was finally defeated and destroyed by the unified forces of the Crucible (what I'm calling their home world, please bear with me.). They spent the last few years hunting the remnants of the Fusion to prevent them from regaining strength.
To prepare for another war like the Fusion Wars, the Crucible developed an elite military force called the Crucible Armed Forces (CAF). They were cloned soldiers (NOT ******* STAR WARS) trained to fight against any threat, alien or domestic.
Five generals commanding this army consisted of General Uno, General Foster, General Utonium, General Lance and General Jack, but either went missing, or rogue.
General Utonium, Hoagie" P. Gilligan and Dexter created the Science Division, devoting their lives to researching weapons and other things to help their world.
Dexter was reported missing after the final battle of the Fusion Wars. It is rumored that Dexter either deserted the army, went missing, or was killed in action. Rumor has it that Dexter was developing robots to use against the Fusion Forces but the project ceased continuation during the final hours of the war.
The Fusions would assume the form of an almost identical copy of the characters from Cartoon Network (like Dexter, Samurai Jack, etc.). Because of their imperfect resemblance of the characters, they were referred to as "False Copies". The last of the False Copies assumed the form the Powerpuff Girls when they were younger (I'm referring to the PPG Reboot). This fooled some people but they immediately knew they were impostors because the real Powerpuff Girls are at least 21 years old now.
The last False Copy was destroyed at the hands of the real Powerpuff Girls and Commander J. Morris of the Ghost Battalion. The Ghost Battalion is a military branch designed for operations against alien and otherworldly threats. Their design is based off of WW1 German soldiers (pic related). Commander Morris was also accompanied by his second in command Sergeant Kronus, Privates Edwards and Stuckey and at least one hundred troops at his command, with assistance from the real Powerpuff Girls.
After the destruction of Fuse and all of the Fusions, new threats had surfaced. Johnny Test went insane, became a terrorist and had his sisters develop robotic soldiers against the Crucible. Another, much bigger threat had also arisen. A realm consisting of raw energy and dark magic had opened. Within that realm lay only horrors and monstrosities. This realm is called the Void. The Void's goal is to corrupt everyone and everything in its path to build its strength. With this new threat, Ghost Battalion must destroy this new threat, before it consumes them and their world.
THAT WAS ******* AUTISTIC JESUS CHRIST. THAT SOUNDED LIKE A BAD FANFICTION. CHRIST ALMIGHTY, I NEED A NAP.
