Also applies to any of the dozen or so characters who 'stop time,' ranging from Kang to mutants like Tempus, Tempo, Kiden Nixon, Sway, Lacuna, Timeslip, etc.
If they *actually* stopped time in a localized area, that area would fly off of the planet at the speed which A) the planet is rotating, B) the speed the planet is spinning round the sun, C) the speed the solar system is spiralling through the galaxy, D) the speed the galaxy is hurtling through space! (Quite possibly four different vectors and velocities! And if the time-stopped area is on the side of the planet facing towards it's direction of rotation around the sun, the area would plunge straight down into the core of the planet and out the other side, causing unimaginable devastation.)
Plus it would get super-dark in that area, since no light would leave it.
Kang would be all like, "Hah, time freeze! Oh brilliant, now I can't see what's going on in that area, affect anything in that area (since any attack stops moving when it hits the edge of the area, making everyone I time-froze effectively invulnerable), and they can't even hear me monologuing, since sound won't travel into the time-stopped area..."
