Probably the fastest cartoonist on the face of the planet, Sergio is as well known for his marginals in Mad Magazine as he is for Groo. He had a little stint recently with another comic, entitled The Mighty Magnor for Malibu comics, but I think he finally knows where the money is. Without this man, there is no Groo. We are all thankful.
