30 Day VILLAINS challenge, day 10: Overpowered / All-powerful villains

Welcome to another 30 day challenge which in honor of spooky season will cover the topic of Pop Culture Villains!

For an antagonist to be effective they have to pose a certain level of threat, and there can be a certain fun in cranking up that threat level as far as it can go- sometimes too far. Where we covered master strategists in tuesdays prompt, we now turn to villains who are just absurdly personally powerful, whether through limitless physical strength/durability, an insanely useful ability, or nigh omnipotence.
Regardless of what flavor we’re talking about, the main prompt of today is: what are your favorite ludicrously powerful villains? Do you enjoy this trope? Who was superpowered in the most fun way?

Bonus prompt: The Worst/most boring overpowered villains? Worst/most boring form of being overpowered?

Maniacal prompt: Villain with skills so overpowered they needed to be forgotten/ignored for the villain to lose?

Machiavellian Prompt: Best and worst cases of long-running villains suddenly becoming wildly OP – or of major threats falling to hastily handled hassles?
