Meet Patchwork!
He is the final boss of my fanfic story CD Saga; he activates when CD Sfarx leaves the Centralis Eye Scanner in the simulation during one last brawl with his counterpart at the Orbital Ring after misuse over time during their brawls to make CD Sfarx more powerful. Patchwork awakens stuck in the simulation having a body but not the means to travel outside of the Simulation like how CD Sfarx does so he waits for him with his minions to comeback to the hidden base that links both the sim & real world together while also doing redecoration of said base. After coming back CD Sfarx is very angry at the sudden remix of his base & gets ambushed by Patchwork (something that CD does alot not liking the tables turned on him).
His minions CD Oscuri & Sfarity try to help him but they are all out matched & in a last ditch effort CD Sfarx teleports all of them back outside the real world. Having to bite the bullet they all realize they need help from their counterparts to defeat Patchwork, who plans on continuing Clarity's plan of keeping GPAs & Formies into the simulation. Not liking the sound of this Sfarx, Oscuri, & Osarx agree to a truce but only because they want to stop Patchwork from achieving his goal. However they have to go through this new base to reach Patchwork, once they do they are ambushed & the fight officially starts for the team.
During the boss fight Patchwork unlike most enemies WILL NOT GLOW AT ALL. Everyone has to pay attention to sound & visual cues to properly dodge/attack/parry him. If the Team's HP gets low then Patchwork will start to crack jokes & leave himself open, sometimes will be seen laughing in place. He's just like the other combat datas where if the counterpart is struggling then they taunt alot which is a hubris that Patchwork has.
Theres 3 phases in total however, in the last one Patchwork will be more focused on CD Sfarx so he will ignore the rest of the party, thats because he wants to possess him to be reborn as a new being. One that can assimilate anyone in the real world while teleporting to the sim to take care of them in his "utopia" (pretty much same thing Clarity was doing but doing it with alot of goofying around/menacing feel to it). So the sooner he can weaken the copy the better since CD Sfarx killed Fark & Spark he gained control over the simulation but instead of carrying on what the Claritas wanted he uses the powers for his own to create a power up booster (that being the centralis eye) to mess with Sfarx Neo & kill whoever he wants on Luna much to Patchwork's disliking. The battle is very close, ultimately the one who lands the killing blow is CD Sfarx which was a huge mistake because he basically ends up destroying himself, data starts to scatter but CD Sfarx manages to latch on to Patchwork's before disappearing into the out of bounds area of the Simulation. Something that the heroes are unaware of until way later in the future when these two return merged as one.
