Hi, here's my proposition for an infector character.
[hider= The Redeemed]
Name: Sarah Lowell
State: Infector
Personality: Sarah is one of the first to willingly witness the change. She was conveniently placed, ran out and immediately understood the blessing that had been placed upon the world. In her mind, some kind of rapture. A reset. And given her being one of the relatively fortunate ones, a blessing. Sarah had already been a broken woman before the change. So this is really an opportunity for herself, she figures. Despite an overwhelming urge to expose the few cowards to sunlight, she is reasonably sane and surprisingly sociable and eager to rebuild with the surviving infected.
Appearance: Sarah used to be a beautiful (if poorly cared for) young woman. Skinny before the change, she is now a gaunt giant, completely hairless and pale. She has been transformed into a sexless ghoul-giant. Still humanoid, but stretched and elongated. Her skin is so pale in certain warm lighting you can almost peep through her taut skin and peer into the alien machination going inside of 'her'.
Biography: Sarah has lived in this city her whole life. In this apartment building for most of it as well. Her single mother worked herself to an early grave, and the bad crowd she used to replace her didn't improve Sarah's situation either. Being very young still, no relatives, very little except for her mother's small nest egg and a long-term lease; she turned to the only other people she knew. The same bad players that had plagued her life so far. By the time of the change Sarah is abusing drugs and being abused by men. Her cycle of self-destruction is halted and cleansed by the change. In fact the current scumbag she was currently let leach off of her that she had kicked the night before had knocked himself out in some alley nearby and melted into a large mold on the side of the building. New Sarah thought he looked beautiful like this. Maybe it was the peaceful look on his face.
Talents: 
[u]Inhuman strength & constitution:[/u] Over about 6 hours after her initial witnessing Sarah started to slowly shift into her current state, first steadily losing her hair while contorting at various rates, at points the pain of stretching rendering her unconscious during the process.
[u]Fresh new attitude:[/u] Sarah feels better than ever. Isn't the sun beautiful today?

I could also make a second character if you're interested.
