I make a Poster, you pick it, and then debate with it.
The rules are very simple. Your Poster will have a possible brief description of the certain character version in it. Other than that it is assume current versions. Unless the Description describes other wise. Unsure which Version? Just ask.
Also all characters have Standard Gear and in Character.
Any Character with Gear or Power Like these cannot be used. Time Stopping. Reality Warping. Summoning. Duplication.
Everything else is fair game.
So with that, as they say in the navy, pick your rate, choose your fate. You can pick Posters someone else picked.
Have at it.
