Milo Danger Murphy is the titular protagonist of the Disney Channel series Milo Murphy's Law. He is a young boy who is the descendant of the creator of Murphy's Law (which in the series refers not to the real-life originator Edward A. Murphy Jr., but rather Milo's great-great-great-great-grandfather, Sheriff Murphy) If something can go wrong, it will go wrong. Because of this, many accidents and catastrophes happen when Milo is around. Milo is the youngest child and only son of Martin & Brigette Murphy, the younger brother of Sara Murphy, and the best friend of Melissa Chase & Zack Underwood. He is also one of the five titular characters of the Phineas and Ferb/Milo Murphy's Law/Hamster & Gretel Universe, the two of the other four being his good friends Phineas Flynn and Ferb Fletcher, and the other two being Hamster & Gretel Grant-Gomez.
