Byo Byo no Mi

Byo Byo no Mi (びょびょの実) is a devil fruit that gives its user all the capabilities of an entire hospital. The user can use their hands like scalpels, charge them like defibrillators, dispense medicine and perform other medical practices related to hospitals, essentially making them a one-man, walking hospital. However, the user's effectiveness with the fruit is highly dependant on their already present knowledge of medicine, and without it, the inexperienced use of such advance medical tools and abilities can spell disaster for the user's potential patients.

Etymology

 * Byo (びょ) comes from Byousha, the Japanese word for hospital, infirmary, and ward.
