-Saitama vs Darkseid/ vs Doomsday/ vs Broly: Saitama (aka One-Punch Man) is well known to be possibly strong as Superman and/or Goku. He has also been seen in fan made scenarios with Thanos and the Incredible Hulk. There are three other heavy hitters though that no one seems to discuss, whether they haven't thought about it or they might very well know the answer. Those three are Darkseid, Doomsday and Broly. In my opinion, it might be possible that even if Saitama goes all in, both DC villains may have the advantage due to Darkseid having his Omega beams and Doomsday being already through dealing with brute force (can't kill him the same way twice). The one that might be most debatable, however, is how the one punch man himself might have it in for him against the legendary super Saiyan. While he might try matching them in brute force, Saitama (as far as I'm concerned) may still have difficulty against these brutal characters.
