Martin "Asu" Adley is the younger brother of the Adley family. Martin was adopted at the young age of four and has been part of the Adley family ever since. He is a carefree, enthusiastic, and energetic young man. He isn't too interested in detective work and often slacks around the office, doing nothing all day except watching TV and taking care of Bean, his pet cat. While he looks intelligent and wise on the outside, his brother would describe him as "having the IQ of a goldfish with dementia". He loves making perverted jokes, playing soccer, and looking after kids. His dream is to build a cat shelter and take care of the abandoned cats on the streets of London and hopefully help them find a better home.
