Detective Speedo's appearance in the manga.
Detective Speedo (海パン刑事, Kai-Pan Deka) is the head detective of the Special Detectives Unit, famously known for being almost buck-naked, save for his distinguishable black Speedo-style swim pants from which he can take out almost any object imaginable (to the shock and revulsion of others), necktie, long socks, shoes and strapped-on weaponry which wrap around his shoulders and knees. His necktie appears to be the source of his immense strength and, more importantly, lack of shame from exposing his groin during battle scenes against his opponents.
Real name Takeshi Kitano (汚野たけし Kitano Takeshi). His codename is short for Kaisui-pantsu (海水パンツ swim trunks), while his real name comes from comedian Beat Takeshi.
