Okay I am allowing all of you who voted for Superman to rank him higher then what vs battle wiki put him at however the limit is multiversal no hyperversal or anything higher then that. Also no immeasurable strength feat. I know he was just lifting his burdens and not the actual heavens. Also no outlier feats or situational feats. However any other possible argument for Superman is allowed.
Discord has fourth wall awareness and reality warping . He can easily discover superman's weakness to kryptonite and use his reality warping or time manipulation to create genuine gold kryptonite to wound and kill superman . Not only that but Discord is the embodiment of chaos so that means he'll be difficult to put down .Discord could also erase the sun which could deprive superman of his powers. He's also very vulnerable to magic and well discord is a magical being . Superman is not only gonna die to discord ,he's gonna have his soul sent to darkseid in a jar as a gift hahaha .
