Pebble is a bundle of frantic energy with skin the color of wet river silt and a wild mane of hair that looks like spun copper wire. He moves with a jerky, caffeinated rhythm, often tripping over the hem of his oversized leather apron which is heavily stained with bioluminescent oils. His most striking feature is a set of four specialized goggles stacked atop his head, each with different colored lenses of varying thickness. Despite being a master of light, he is almost entirely colorblind, relying on his gadgets to translate spectrums into sounds. He smells faintly of ozone and expensive glass polish.
