Killmost

According to the ghost of Captain Milquetoast, Killmost was his great-great-grandfather and the first member of the Milquetoast clan to be known by the name "Milquetoast".

History
Not much is known about his history, or his real name for that matter. What we do know is that he was a very deadly pirate who was "fond of nicknames". After one of his adventures on the sea, he demanded that his entire crew call him "Killmost", so people would know that he was responsible for the most deaths they caused. Unfortunately, he demanded this after several of his celebratory drinks and he slurred his demand quite badly, resulting in his family's surname, "Milquetoast".
