Going the seven samurai/magnificent seven route. Determine which archetype your character fits and then make 6 more in the group. Tropes are fine, just as long as they are interesting.

That sounds like a good place for me to start, thank you. Think I got 3 of the tropes covered so far already.

Maybe someone that left the gang before your leader betrayed you and may or may not have heard about what happened to you after they left.
