Hi, I'm Quin, and this is Amanda. She's a rather naive teenage superhero who has no clue that her powers come from a failed drug trial that killed a bunch of people, including her biological mom. Or that her adoptive father designed the drug. No I didn't create her backstory just so villains could screw around with her, why do you ask? Anyhow, she has limited shapeshifting (limbs into anything she can imagine, including weapons, but no full-bodied shifting) and a pretty much complete immunity to any toxin or disease.
In general, Amanda's a pretty happy kid, if a little shy. She might off as a little fangirlish to other heroes, especially anyone who's shown up in the media a lot; she still feels a little overwhelmed by the superheroing thing most days.
If you want to reach me, my AIM's epitomal but I'm not on too much, so a PM or an email at quin.gaming(at)gmail(dot)com is a better bet.
