Hellrazors

The Hellrazors are surviving (not all of them) antagonists, antiheroes, or grey characters of the Hellaverse who were save by Mephiles the Dark when Cinos was merged with another variant of him (one with the Harbin Hotel cast, the other is with Helluva Boss cast) with the addition of the Potis Atiare as he was trick by Malware as he hope being overload with Shard energy which will kill him, it's didn't but damage his body.

Mephiles the Dark told these demons and others too worked with Dr. Eggman who also return from many adventures in the Multiverse as he wasn't split into variants. Eggman recall of few of them but accept many, he formed an alliance with them in hope to capture Cinos and extract Shard Energy from him but they eventually betrayed him as he work for the Chaos Council during the Metal Virus. After the Metal Virus was decimated and the Chaos Council, they made an alliance with Malware who they don't trust but have no choice as they meet and work with other villains.

The leader of the are Adam as he have a hatred for Charlie, Vaggie, and the others of the Hazbin Hotel, Paimon as he have hatred for Blitz, his son Stolas, and the other of the Helluva Boss, and the true leader is Satan who desire to ruled Earth as he now want the place to be a new Hell so that he will be king, King of Planet Hell and ruled over all life. He becomes one of Cinos' recurring and dangerous enemies, one of the main antagonists of Cinos Aftermath. After the Convergence and turn out that Hell was  not destroyed, the team was disbanded as few were not wanted and banned from Hell due to a new Oligarchy of Heaven & Hell. A recurring sub-plot in the Cinos Aftermath is about the Batman/ Catman relationship of Alastor and Lute, they eventually became official in my theoretical Cinos Next Generations.

Technically not all of them are bad or terrible since they are more grey
