P.S. Is it a flat requirement to fill out the arc pitch section of the CS? I have many arcs to play with John but giving a good three of four of them away seems to spoil the fun somewhat.

You don't have to spoil anything. That part of the CS is just to give us an idea of where you are going with the character. 

As for villains, I was thinking of putting together some sort of collab system to deal with that. The problem with making villains actual full time playable characters is the threat of a player disappearing. If Green Lantern disappears what do we do with Sinestro? Plus if, for example, I wanted Lex and Superman to interact and fight in a certain way or I had a plan for a Superman arc I wouldn't want to tell the player playing Lex how to play their character. See what I'm saying? 

However I do see the potential in players playing as villains and there's no denying that there is a fun dynamic to that. So I've been thinking that if a player were to play a villain, the hero could ask them to do so. The player playing as the villain would temporarily take that character over and write a sort of collab arc with the hero. And say if Batman wants to, he can allow a player to take over as the joker every time Batman has an arc against the Joker.

I am of course open to suggestions on how to make this work!
