I have a few ideas for a character. The last (good) Zombie RP I was in died because the GM had real life crises. These ideas were considered in that last Zombie RP, and also in one or two that aren't as good. Anyway, here they are:

The Wild Child (Approved and used): This was the one I used back then. A 10 years old girl who had been through things that even a soldier shouldn't go through. Family picked apart one by one by zombies, losing friends one after the other, forced to fend for herself, turned to robbery and other vices to stay alive... By the end of it, she'd lost most of her humanity but is consequently a surprisingly good survivalist and fighter.

The Astronaut (Was once approved and used when it was a bird alien that landed on a fantasy planet. I'm not kidding.): After spending as much time as possible in orbit, he and his fellow astronauts were forced to land due to lack of supplies. What they found after that was nothing like they could imagine, something straight out of science fiction. He would likely be equipped with state of the art, space-age equipment, at least initially.

EDIT: I'm not sure what profession he'd be. Engineer or biologist, he'd still be invaluable.

The UN Protector (Approved and used but I left the RP because of bigotry): A foreign soldier who probably came in to scout ahead of an upcoming mission. His unit was lost to either zombies or people or both. But he stayed true to the mission, acting as mediator and voice of reason to resolve tensions wherever, and performing one-man humanitarian missions, rescues and such.

I imagine this incarnation of him to be a Japanese national who came from a Japan that was devastated, but still functioning 'properly', as in having farming and manufacturing capacity, government. He would likely be part of a military unit specially trained and equipped towards putting down zombies, something like a mix of soldier, riot police and samurai. His equipment will be state of the art at first.

EDIT: To 'balance' him out, I'm thinking of making him a medical officer, and someone who was 'forced' by his clan to join the military before the outbreak, and as such is not exactly the best soldier there is. But he would be an excellent traditional warrior (because he finds solace in art), surgeon, general practitioner and... pediatrician (he was first those three before he was a soldier).

Which do you guys think is best for this RP?
