Master Mummy (マスターマミー, Master Mummy) is a character and playable fighter in the Nintendo Switch game ARMS.
One of the playable fighters in ARMS, Master Mummy lived and died many years ago. He was resurrected as a mummy possessing the ARMS gene by Dr. Coyle during her experiments. He has now dedicated himself to searching for his lost family, but has completely lost his memory. His home stage is the Mausoleum where he was resurrected. If Grand Prix mode is beaten with him, his victory photo shows him reunited with his wife and young son, both of whom are also mummified. Master Mummy's standard ARMS are the Megaton, the Retorcher, and the Phoenix; he utilizes two Megatons in Super Smash Bros..
Master Mummy is seen in Min Min's Final Smash, ARMS Rush, and unleashes a flurry of punches alongside other characters from ARMS.
