CandyApple

The left head is Candy, the right head is Apple. Together, they are CandyApple, and they couldn't be more different. They are so distinct that they genuinely act like two entirely different dragons, and they never communicate with each other. They aren't hostile--they simply don't acknowledge each other, to the point that they almost seem to be completely unaware of each other. They have some kind of internal synchronicity that means they are able to move and talk and function together, but each head is capable of doing something totally different from the other. They can carry on separate conversations and do different tasks, with each one utilizing their half of the body to do so.

They're the most mentally stable of the Abbys, and the most physically unstable. Their body is amorphous, constantly changing and melting. They're kind of like a living non-Newtonian fluid. Their stability fluctuates, and a bout of instability is considered a "flare up," where they are in danger of literally falling apart. In this state they will often leave goo around, and will have to stay in one place since that's basically their body parts, and if leave they run the risk of leaving behind a literal piece of themselves. This is often a life-threatening condition.

Patina, Nephrite, Poxxen and Mictlan all got together to construct a mechanical attachment for them that connects to both of their brains as well as to their spirit. Using this construct, they are able to stabilize themselves through willpower and concentration. It's not a perfect solution, but their quality of life has increased dramatically, and they're eternally grateful to the clan for helping them.

Candy is bright, cheerful, and bubbly. They're a mathematician, and entertain themselves by proposing and solving complex proofs. They also handle any number crunching or accounting needed by the clan, which they find a bit boring.

Apple is quiet, serious, and intense. They're a painter, specializing in oils with occasional mixed media, and their work is often very solemn and emotional, utilizing lots of dark colors and chiaroscuro. They're not pretentious, however, and are enthusiastic about deep discussions about art and meaning.

They split their time between their interests evenly without ever needing to discuss it.
