In my opinion Pennywise only failed because he was playing around with his food too much (to add flavor I guess). He should have killed them outright. You can then travel worlds and kill ****ty people like Voldemort, Celestial dragons (One piece) , Kaido, Big Mom (She has soul powers so it'll be cool to see their confrontation), Game of thrones , Nobles in Akagame ga kill, RWBY etc..
