Marvel Zombies vs. DC Rage
This is me trying to think outside of the box, people. If you think this is a shitty idea, them go piss up a rope. 🙂
All characters from the Marvel (film) Universe will have the zombie virus from the 2004 Dawn of the Dead movie. They will all retain their abilities/powers, and will be dead, but newly re-animated as to ensure optimal movement and posture from rigor mortis.
All characters from the DC (film) Universe will have the Rage virus from 28 Days Later. They will retain their abilities/powers, but will be mindless and vicious creatures that will attack and kill anything they see.
For the sake of the debate, all characters will be able to use their powers/abilities while in infected state.
Remember that both sides are HIGHLY contagious.
