Have you seen Death Battle, on youtube? I was thinking we should make something like that, where we compare aliens, weapons, characters, and so on to find out who would win... an Alien Battle!
We could take canon characters like Vilgax and Charmcaster, and pit them against other characters at specific points in their life, and pit against original fanmade characters! We can also have original characters fighting against each other. And alien forms, too! Ever wondered if Jen 10's Fourfists(Fourarms) is stronger than Bill 10's Thunderoar(Shocksquatch)? Ever wonder how the Ben 10 from Universe 53 would fare against the heroic albedo of dimension 74? Could your original Omnitrix-wielder defeat Orochimaru, The Thing, and Darkseid? It's hero time for everyone, and it's time to find out who's the mightiest hero of all!
We could also use the round-based system https://www.reddit.com/r/whowouldwin/ uses. For example. a "Ben 10 VS Vilgax" fight could be "Round 1, he doesn't have the Master Control. Round 2, he has the master control. Round 3, he turns into Feedback".
We'll just need a few rules like "No omnipotent reality-warpers, no turning into Alien X, no travelling through time to kill your opponent before he shows up", and so on.
A lot of people here just make their characters and serieses and they don't do much with them. But if we use a system like the VS Battles Wiki's, it will encourage discussion between creators and cooperation between writers! I think this would work best as a new dedicated area of the forum, where threads are made to pit characters against each other. People read through the profiles of these characters, respectfully debate over who'd win, and then choose.
