Lets see here, we're arguing that the Surfer, Thor, Warlock, Drax, Hulk, etc,,should be able to beat Thanos, but yet thanos has beaten them countless times (some at the same time) and people are saying that Superman can beat him? So in the same breath, Superman should be able to beat Surfer, Thor, Warlock, Drax, Hulk, etc,,, everytime with relative ease? I dont think so.
Honestly, Thanos is far above the aformentioned characters. Yes, he is more durable than Superman and could withstand any attack Superman attempted. Thanos on a regular basis fights and holds his own against characters like Odin, Galactus, Runner, etc,,,,.
This is dumb. Sorry to all, but Superman loses.
