how to create your BBEG in a fantasy story, assuming you already created a world and have a rough idea of the history of it and its power system. then created the mcs to experience the world and some side characters that has some form of interaction with the mcs. but how would you come up with the BBEG, does he have to be catastrophic level. world ending. demon lord type of villain. i don't know how to put a twist to it. the story itself won't be limited to a local setting. they would have to go all over the world, so it would make sense the villain is a world level threat?. rough idea i have would be the first ever human which created the power system. but i don't know how he would be evil since hes a good guy and is already dead, corrupted? brought back from the dead perhaps, idk. anyway, just wanna know your experience how you create your BBEG
