The mouse version of Dr. John H. Watson, Dawson is the trusted associate and official biographer to the famous detective. A military surgeon whom returned to London after serving in the Queen's 66th Regiment, Dawson appeared to Basil just as he was starting out in his career. The two became good friends and decided to get into a business together to help others in their world. The year was 1885 when he published Basil's case about their neighbor's missing twins. Unlike his movie counterpart, Dawson is very lean, though noticeably shorter in comparison to Basil. He has stated before that his friend is one full inch taller than him.
