1nkwell - An Fgod Nightmare

It took several centuries but Nightmare was finally defeated. The multiverse would be mostly at peace. At least until Error's next homicidal au destroying spree. However, his SOUL wouldn't shatter like most and would always pull itself back together from a sludge of pure negativity. Error, who had defeated Nightmare, decided to stick him in the antivoid strung up like he does with DETERMINED SOULs but Nightmare of course escapes. However, time in the antivoid made him a different person, a different monster. A glitch. Glitch enough that he could escape the antivoid. However, the antivoid wasn't just a singular realm. Unlike the other realms, it connected different multiverses. Now the citizens of the Fgod multiverse would have to deal with this new glitch which called itself: Helper.
