pretty much all fiction has this tbhDeath of the Author is a precious thing.
Remember when The Flash gets clocked in to Mach 5 or 4, when he literally was watching a real life lightning bolt in slow motion?
good times. Writers can be stupid
jojo you got josuke saying his stand moves at 300km an hour even though in the same story he beat the shit out of a guy who moves at lightspeed
pretty sure mcu has tons of feats that contradict quicksilver being mach 1
wouldnt you need to be much faster than that to save hawkeye from machine gun fire at the end of the movie anyways?
