I'll ask here since it's coming up a bit now for [@Master Bruce] and [@Lord Wraith]. Where does the GM stand on establishing 'title characters' to fulfil other people's stories?

Per Examplé (Read it in a French accent, it's better), if I was playing The [I]Flash[/i] and there was no [i]Martian Manhunter[/i] player, yet I wanted to use that character to tell a story, how much of [I]Martian Manhunters[/i] backstory could I elaborate on?

I guess I'm just worried that at some point someones going to establish something that will put someone else off applying.

Ew I posted. As always feedback appreciated.

I can't speak for MB, but it all depends on the player's intention. If you're just name-dropping characters to flesh out the world, I'd ask you to be open to someone applying and maybe tweaking the interpretation. If the character is a recurring support character, appearing in a bulk of your posts, then that's different. They should be on your sheet so that at the time of your application it would be considered ala your situation with Thorunn and Mangog.

A player is better than an NPC at the end of the day but I realize I am the worst person to say that since I'm a large offender for not wanting to share toys in my sandbox. At the end of the day, it's why I have stopped going after characters like Batman and Spider-Man who do have very popular supporting casts. 

One last thought, the character in question also matters. If you're playing Batman and you make Nightwing a supporting character, that's going to rub people the wrong way. But if you're playing Thor and you make Eric Masterson a supporting character, much less likely to raise an eyebrow or objection. 

Sometimes your posts might even inspire someone to apply as a character solely because they think your stories look fun and they want in. It's ultimately a case-by-case process for me.
