Men in motion
Trion juggernaught has stalking walking already. He's in full motion.
Superman prime was sun dipped and wearing the armor from crisis...
Smp flies from the sun to earth hitting maximum speed along the way heading in an opposite direction
two trains in motion collide head on. Who gets pushed back
My first inclination was to say that Trion Juggernaut would come out on top, but I am not entirely sure.
I mean, Prime at 'normal' levels was casually moving planets around (at considerable speeds) like they were ping pong balls. Now you're amping him, giving him the armor, AND allowing him to reach max speed (light speed+) before he collides with Juggs... It's hard to imagine anything enduring that type of force.
