We all have creative trouble from time to time. One way I've found to alleviate this is to flesh out a character concept to see if it's something I'd enjoy, giving it a full story and history before eventually (usually) abandoning it for one reason or another. And sometimes I play out scenarios and ideas for storylines that don't work out, or end up contradicting something else.
It seems a shame though that these characters will never see the light of day. To that end, this thread. Showcase your orphans, explain what and who they would have been and why they can never be. Someone else may find the way to breathe new life into them, or you may see something in another concept that helps clarify something to help make it work for you.
I had a character who was essentially meant to be a D&D/Pathfinder style Paladin. Defender of the meek and innocent, beacon of hope and light, and symbol of everything good in the world. I didn't really have the patience to build his skills and equipment up (again) and realized pretty quickly that we don't really have room for all of that here. Fists of Gods, sure. Rightous avengers, absolutely, but the quiet, staid faith and strength of character requires a different sort of environment than we have here. It's hard to stand up and protect the innocents in the name of your God, when your God pops in regularly and says "Literally who?" (not a dig at the admin, you guys are amazing and I love you all) and the innocents in question will just be resurrected/replaced when they die anyway, and don't really react to your chivalry or your foes' villainy any differently. Especially when you have to get used to playing musical alliances.
Also didn't help that I chose to make him a series of alliterative puns, and the Peulus family is no more. (Page Pupo Peulus, Prodigal Panda Paladin was the goal I was aiming for. It was very silly.)
