In D&D what you describe is for low level and part of mid level. At the upper end of mid level and higher you have wishes, clones, boons, items, contingencies and more to keep BBEGs coming back as repeat villains.By using an incredible amount of narrative fiat. Superman never beats luthor because he can't kill him, and Luthor always finds a way out of jail.
That doesn't work in most dnd games. The PCs find the bad guy, and immediately kill them....and your story is over. These kind of power imbalance scenarios you see in comics only work because the author forces it to work, when you give players agency these scenarios immediately fall apart.
