Dr. Light Dr. Light is the creator of Blues, Rock, Roll, and a bunch of other robots that I don't feel like naming. I always thought of him more as a father to them then a creator, and I think he fits that part better anyway. Just look at the Bues! comics... anyway, looky at the pictures. Concept sketches of Dr. Light. I almost never draw him. Poor neglected Dr. Light... This was a stupid little doodle of Dr. Light with a young Wytwolf. Just an off shoot sketch from the Bues! comics.
