Sooo we're expandin'. We've got true_comm (also public and with open membership) for a first generation sandbox, because we keep bitching about the character limit at PH. And this is just a ... take from canon what you like and ditch what you don't thing, as usual. I'm just going throw some ideas out there and y'all can decide if you dig 'em or not:
Avengers! (They're established bigshots and stuff.)
Steve Rogers / Captain America Tony Stark / Iron Man Carol Danvers / Ms. Marvel Janet Van Dyne / Wasp Bruce Banner / Hulk Clint Barton / Hawkeye Luke Cage / Powerman Hank Pym / Giant Wasp Yellow Ant Man
Young Avengers! (No one's dead! Being dead sucks!) Cassie Lang / Stature Kate Bishop / Hawkeye II Teddy Altman / Hulkling Billy Kaplan / Wiccan Eli Bradley / Patriot Tommy Shepherd / Speed
Runaways Gert Yorkes & Old Lace Chase Stein Karolina Dean Molly Hayes Nico Minoru Xavin
Independent Peter Parker / Spider-Man Angela Del Toro / White Tiger Anya Corazon / Spider-Girl Matt Murdock / Daredevil Felicia Hardy / Black Cat Angelica Jones / Firestar Tandy Bowen / Dagger Any Corazon / Spider-Girl
Asgardians bb Loki Sif
Other MJ Watson-Parker Dakota North Pepper Stark Jessica Jones
Pre-Civil War, pre-OMD, everyone loves each other, etc etc. So we can post here with the characters we want and someone will put up something silly and hilarity will ensue.
I'm grabbing Wasp, Echo and Spidey straight up. Aaaand Hulkling. Y'all can makes your claims and then I'll start grabbing other people, I just know I have sticky fingers and I want to give everyone else a chance at shit.
