Burke is Chimera of Unknown Origin.

Usually in good spirits he cannot feel Anger as an Emotion. His specific sub-species does not experience it.

Burke is known for being able to twist his body into a multitude of different shapes, sizes and more.
He can grow multiple heads, multiple arms, legs and stretch his torso to outlandish lengths.
His body can change for any situation he needs it to.

His tail is a snake, however it appears to be spaded like a devil tail. The mouth can open, and can bite if needed.

Sometimes he talks about his "home", often described as a white expansive desert. Its characteristics are often similar to a Salvador Dali painting, in which things melt or change consistency constantly, with impossible architecture. Why he left for a more modern life is unknown, but nobody is really complaining.
