Rick was a scientist who had been experimenting with teleportation technology, until one day Rick, who already had an interdimensional portal gun, presented him with the possibility of traveling through the multiverse. When Rick said no, the other Rick felt insulted and murdered Rick's family C-137 with a bomb.
He wears a white lab coat, a blue (or light blue) long-sleeved t-shirt, beige pants, and has blue-gray hair.Rick doesn't take much into account ethics or morals, they don't exist for him.
