"The devil made me do it"
So:
for Supes:
[]Holding back/normal Superman punches harder than Orion's ever been hit.
[]Superman speedblitzes (with what looked to be tens of punches) a high-herald (that also happens to have superspeed)
[]His heat vision is put in the same sentence with the firepits of Apokolips
[]The Lasso of Truth doesn't have total control over him.
[]Is called the most powerful creature on the planet by Hammond
for Orion:
[]Punches Superman from one side of Metropolis to the other
[]Tanks what is by his own words "the harder he's ever been hit", followed by a speedblitz.
[]Lifts a battlecarrier in the space of moments, easily.
[]Heat doesn't seem to pose much problems for him.
[]Mother box pulls Hammond out of Superman's mind, puts mental blocks to stop him from entering again, mind-rapes him (!) and then sends him back to his own body.
Also: both of them were punching at supersonic speed.
Quite a few feats, there.
