Characters who are entirely too strong for their setting

You ever read a story or watch a show and think "Huh, why aren't they using so and so" or "Why would they ever lose with blank there?" or "Purple Haze is my favorite stand?"

TVTropes calls this story breaker power. When a character has an ability that makes them really difficult to write for because they can solve problems by their lonesome. TVT may be a shithole but their descriptions are still very helpful. A good example of this is Quicksilver from the Ultimate Marvel line. Every time he appeared in a story, he was untouchable. The writers had other characters comment that he couldn't be around or do something for one reason or another because a guy with lightspeed is a bit too much for a grounded universe like 1610.

I always love when this kind of thing happens. It's like someone got a little too excited with powerscaling and didn't think about the context or how it would change.

What's your favorite instance of this happening?
