Tokusou Sentai Dekaranger is a 2004–2005 Japanese children's television series in the Super Sentai series. In an iteration of the planet Earth when extraterrestrial contact has been made, the Dekaranger force battles the criminal syndicate of Alienizer.
Special Police Dekaranger (スペシャル・ポリス・デカレンジャー Supesharu Porisu Dekarenjā, S.P.D.) is a police force who make sure that all aliens abide by intergalactic laws, and has advanced extraterrestrial technology at its disposal, giving its officers suits made out of Deka Metal that make them Dekarangers. The center of the Space Police is the Space Prosecution Office on Gowashichoru. Due to the Sion Morse time flow around the planet being faster than the rest of the universe, an eight-month trial on Gowashichoru last ten seconds in Earth time and the Dekarangers can use their SPD Arms to project a criminal's image to Gowashichoru for the Space Prosecution Office's verdict which is usually immediate execution if the crime is severe enough.
All the Dekarangers almost never use their real names in the show and use nicknames instead. The main six Dekarangers have name puns where their first names are based on different types of tea while their last names are based on mystery/crime genre authors.
Nicknamed "Ban" (バン), Banban Akaza/Deka Red (赤座 伴番/デカレッド Akaza Banban/Deka Reddo) was training in space until he was assigned to the Earth unit. He has a chaotic and a bad tempered, but fiercely loyal and friendly personality and also the leader of the team. However, in the Mahou Sentai Magiranger vs. Dekaranger, Ban is significantly more mature and does not seem to be as fiery as he was before. It took a while before he gained Hoji's trust, often irritating him by calling him aibō (相棒), the Japanese word for "buddy", "pal", or "partner". His number is 1.
Ban uses a space martial arts technique called Juu Kune Do (ジュウクンドー Jū Kun Dō, modeled on Jeet Kune Do) when he blends his martial arts skills with his gunfire. Ban rides in Machine Doberman with Jasmine when patrolling. In the "Girls in Trouble! Dekaranger" and "The Movie Version! Dekaranger" ending sequences, Ban plays drums in the Dekaranger band. In the series finale, Ban joined the SPD Fire Squad as a new elite officer. In Mahou Sentai Magiranger vs. Dekaranger, Ban returns to help his old team on a few occasions: First when Jasmine gets kidnapped though he's on the search for Agent X at the time, then the first invasion of the Zangyack Empire, and clearing Kruger's name in Tokusou Sentai Dekaranger: 10 Years After. During his time with Fire Squad, he gained an upgrade called Battlize Mode, where the modified Murphy becomes a suit of armor and powerful sword for him to use in the fight.
