So, I'm mainly all about fantasy, but my brain periodically "changes genre." For a while now I've been all about superheroes, which occurs once a year or so. Been thinking about super-speed, and how it's widely regarded as the most difficult power to write. I recall hearing that the writers for the Justice League cartoon wished they could just kill the Flash because his speed was so annoying to write around. (Though I don't know if that's true.) Point is, very often super-speed comes across as very inconsistent and nonsensical just to allow for engaging conflicts. Case in point, the aforementioned Flash from DC comics can run around the world in seconds, pick bullets out of the air mid-flight, and perform complex actions so quickly that normal people can't see him move at all. And yet he's consistently "not fast enough" to stop multiple crimes within the same city, catch projectiles before they reach the victim, and sometimes gets punched by opponents who don't have superhuman speed. That's an extreme example, of course, but the point is that the more impressive you have super-speed be, the more unmanageable it is to write without making all antagonists equally fast or customizing all conflicts to negate it. At the same time, well, it's a super-power: It's supposed to be amazing. So, my question is: In a setting with super-humans who have varying powers, is there a reasonable level of super-speed that is formidable enough for specialized speedster types, yet without making them completely untouchable in physical conflicts?
