Maysa, also known as Commander Beef, is a character from the anime MegaMan NT Warrior. He leads a double life as a fishmonger and a secret government Net Agent. In his civilian persona, Maysa is an energetic, eccentric fish salesman who constantly urges others to eat fish, exercise, and take calcium. He pretends to know nothing about NetNavis or Net Battles, despite being a skilled operator. As Commander Beef, he becomes a competent, no-nonsense leader who speaks with authority and coordinates operations against cybercrime. He operates the NetNavi SharkMan.EXE and serves as the superior of fellow agents Sal and Miyu. Maysa’s motivations center on protecting the cyberworld and mentoring younger Net Battlers like Lan Hikari, often supplying them with battle chips and strategic advice. He is a recurring mentor figure in the first season, occasionally appearing in later series. His key relationships include a rivalry with Higsby for the affection of Ms. Mari, and a respectful partnership with Lan. Maysa develops over the series by gradually revealing his competence and loyalty, though his civilian disguise often causes comedic misunderstandings. His notable abilities include his expertise in fish trivia, his physical fitness, and his tactical skill as a Net Battler. As Commander Beef, he is known for his deep voice, confident demeanor, and thorough knowledge of net history and viruses. Despite his secret identity, he sometimes lets his civilian habits slip into his commander persona.
