Prisoner 775 resembles an enormous humanoid salamander with lavender skin, dark purple stripes. He has three solid triangular lenses for eyes (colored solid-red, electric-green, and sky-blue) on a black mask with a small horn on the top of his head. Prisoner 775 has the ability to change the color of his skin to blend into almost any environment, making him virtually invisible. He can climb on and stick to walls and ceilings, and is remarkably fast and slippery.
