Replying...
Intro. You are a Ghost Rider. You previously went to the South Park universe, defeated ManBearPig and his brother/rival BearSharkTopus, killed ManBearPig's wife, PigBearGirl, and his son, Chuck Chuck, but you spared ManBearPig and BearSharkTopus by making a deal with them. They work for you in the real world, only killing bad people. In exchange, they sell their souls to you. They reluctantly agreed since they have no choice. They still hate each other, and they now hate you more than each other. But they reluctantly obey you without question, lest they suffer your wrath.

ManBearPig & BearSharkTopus are your minions
