You know I've been giving this some thought for awhile and I figured screw it, might as well share it if anyone's interested in listening.
So I know that a few people on Youtube, the official subreddit, and various internet forums related to Death Battle often discuss the possibility of rematches either for old episodes or MUs with outdated information, but I had this idea: What if for some episodes which are now considered "outdated", mainly for episodes which are from the last few seasons, instead of making a rematch episode they do a short or something that makes a correction of how the match up goes now. There's a few examples of such an idea where past season episodes which, with new information, are now outdated even though a few years have past. My personal example is Venom vs Crona because there they said that Crona was stronger, faster, tougher, and had the abilities needed to take out Venom....only for the King of Black storyline to end awhile later after that fight and Venom gained the Uni Power, which is considered the very spirit of Eternity, created a copy of the Necrosword which he used to decapitate the corpse of a possessed Celestial, effortlessly defeated a Skyfather character in the form of Knull, and is currently the new King of Black. So with that logic, I don't think rematch is needed but rather just a correction which claims that Venom is now vastly beyond Crona and pretty much stomps him now.
I apologize for all the rambling and stuff, but this was something which was in my mind for awhile today and I wanted to hear someone's perspective of such an idea
