Silver Surfer stomps.
Who has Surfer stomped on Atom's level? I'm talking DCnU Atom here.
Firelord, Loki, Morg, Terrax. All at least CA's level. He didn't stomp them, but showed clear superiority.
Actually if I remember correctly, Loki showed his superiority over Classic Surfer.
I forget exactly what happened. But the rest I am sure of and they are PC users as well.
