Morgana

Summary
Morgana is probably the person with the Worst mutation. She resembles a blue-ringed octopus in coloration and skin texture, with four pairs of tentacles instead of hair. This serves as warning coloration, as her skin is lined with microscopic needles capable of injecting magical poison that's nearly instantly lethal to all but a scant few.

She has a few other octopus-like quirks, too. Her bones (less so her skull) are fairly malleable and can be stretched or bended without causing her harm. She's even more flexible than a contortionist, able to fit through openings less than half a foot in diameter, or kiss her elbow. She can also breathe underwater and control the intensity of her coloration.

She's very brooding and gloomy over her mutation, especially as she's traumatized over the number of people who have died to it so far, including her parents.

Trivia

 * Only direct skin contact is lethal, thus she constantly wears long-sleeved clothes and gloves even in summer.
 * Morgie can "hold back" her needles and touch a person without killing them, but its like a reflex, like laughing when being tickled. She can't do it for long, and it always happens automatically if she doesn't have time to prepare.
 * Anyone who has a constitution high enough to survive her poison will find the effects wear off within a few minutes, but it can take a long time to recover. Nessie is one of the few people who can survive, simply due to how big she is. Prolonged contact won't make much difference, there's only so much venom she can inject at once.
 * Touka is completely immune to her poison.
 * She's been 5'2" since she was 14 and hasn't grown an inch taller since. Never weighed more than 100 pounds.
