Dr. Sonnerstein is a surgeon and a geneticist who lives in the Gut. He was the first to confront Loosestrife and accuse him of being the one that was manipulating Stargirl Macbain. Despite his insistence that he means no harm, he is still prone to moments of mad science. This, and his mannerisms and appearance, have lead many people to distrust him.
He has a large adopted family made up of former urchins and other abandoned children, though Scald Sonnerstein is a blood relative of his.
