The first season of Keluang Man introduces Borhan, a resident of Hospital Bahagia in the fictional Malaysian town of Tumpoi, who secretly becomes the masked crime-fighter Keluang Man. Although he possesses no traditional superpowers, he relies on courage, agility, instinct and unconventional tactics to protect innocent people. He is eventually joined by Samad, also known as Tiong Man, and together they confront unusual criminals and colourful villains, including Meow, Johan Hitam and Majid Kilat. Their adventures frequently frustrate Inspector Sahab, who regards the mysterious vigilante as a nuisance, while reporter Kathy Ismail becomes increasingly interested in his identity. Combining slapstick comedy, action, satire and distinctly Malaysian characters, the season establishes the series' playful interpretation of the superhero genre.
