Godblast will have no effect on him, well written champion will smoke them in a second. None of their powers will hurt him, champion will knock out superman with a plantery destroyer punch, Thor will just teleport away after he see's superman goes down like a tone of bricks after a couple minutes. Well written champion when he is not jobbering is unbeatable.
Champion will kill them both, when Champion jobbers he will get his ass kicked, but when he doesn't jobber will flat out kick their ass. Even thanos didn't wanted to get into a h2h combat with him, even he is not that arrogant and these two are not Thanos.
Champion fighting Galactus even rocking him with a punch, ddefeating every hero in h2h combat in contest of champions, defeating SS in issue # 85. Champion in h2h comabt is like the Karate Kid of legion of superheros with billions of years of fighting experince and unlimited strength, speed, indestrcutable, stamina, endurance, godlike reflexes.
Well written champion 10/10
jobber champion will lose.
I'm neither , but have a rationale sense of whom beats whom , And these two certainly lay the smack-down on Champion.
Supes can speedblitz champion for a few seconds , knocking champion off balance , long enough for Thor to get a good storm going as thunder repeatedly strikes Champion. Heat vision interludes lobotimizing the elder and BAM . We're down one Elder of the universe.
