Main characters

Dekarangers

The eponymous Dekarangers are members of the S.P.D.'s Earth unit who utilize the SP License in Change Mode to transform and protect Earth from intergalactic criminals called Alienizers. In civilian form, they each carry a SP Shooter raygun. They can also use their SP Licenses in either Phone Mode to communicate with each other, analyze items pertaining to a case they are working, and summon their Deka Machines to battle Kaijuki or Judgment Mode to determine a criminal's innocence in a particular crime and whether the criminal can be approved for termination, or "deletion". While transformed, they wield a varying pair of D-Arms sidearms, which can combine to form a firearm-like weapon.
After undergoing further training, the primary Dekarangers gain the ability to assume S.W.A.T. Mode where they wield the high-powered D-Revolver machine gun.

Ban

Banban Akaza, also known as "Ban", is a hot-headed, chaotic, loudmouthed, bad-tempered, yet fiercely loyal and friendly rookie member of the S.P.D., who previously trained in space before being assigned to lead S.P.D.'s Earth unit in the field as Deka Red. While he joins the newly created Fire Squad as an elite officer in the series finale, he occasionally returns to help his original team. Initially having an immature personality, he slowly matures throughout the series.
In battle, Ban is a practitioner of the space martial art Juu Kune Do, which blends unarmed martial arts skills with gunplay. His D-Arms are a pair of D-Magnum handguns, which he can combine to form the Hybrid Magnum shotgun and perform the Magnum Execution, Moonsault Shot, Endless Shot, Hurricane Shot, and Moonsault Galaxy Shot attacks. Using Doggie Kruger's D-Sword Vega, Ban can perform the Akaza Sword Art: Raijin Sword and Impulse Vega Slash attacks.
During the events of Mahō Sentai Magiranger vs. Dekaranger, Ban acquires a variant of the SP License called the Fire Squad License, which allows him to transform the robot police dog Murphy into his armor to assume Battlizer Mode where he gains a rocket booster pack and a pair of siren lasers. In this form, he wields a sword/rifle hybrid, which allows him to perform the Battlize Fire Drive finisher.
As of the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Ban has acquired a red-colored S.W.A.T. Mode vest to signify his membership in the Fire Squad.

Hoji

Houji Tomasu, also known simply as "Hoji", is the professional, yet arrogant and stubborn, second-in-command and sniper of the team who serves as Deka Blue. While he is reserved about his personal life and shows little emotion to prevent both from interfering with his work, he has a tendency to blurt out English phrases such as "Perfect!", "Unbelievable!", and "Super cool!". Due to their differing personalities, Hoji clashes with Ban early in the series, though Hoji slowly warms up to, and becomes friends with, Ban. Later in the series, Hoji applies for a gold badge promotion from the Tokkyou division, but ultimately refuses it due to a personal tragedy. In the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Hoji goes undercover as a shut-in after Kruger's seeming turn to crime to help Ban and Sen-chan restore their leader's reputation.

Sen-chan serves as Deka Green. The oldest of seven siblings from a poor family, he displays nycto- and claustrophobia after accidentally falling into a well when he was a child. He was subsequently rescued by a policeman, which inspired him to take up police work. Despite his usually calm demeanor, he is said to be scary when angered.

As of the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Jasmine is married and has a son named Taiga.
Jasmine's ESPer abilities allow her to pick up on sensory impressions of others by handling an object connected to them or visiting a location her target has been to, though overuse of her powers exhausts her. To control her powers, she wears gloves. Furthermore, as a result of breast-feeding her son during the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Jasmine temporarily gained the ability to teleport herself to any part of the universe, which she loses as of the direct-to-video anniversary special Tokusou Sentai Dekaranger 20th: Fireball Booster.

Umeko

Koume Kodou, also known as "Umeko", is a ditzy, yet kind-hearted and perky, member of the team who serves as Deka Pink, though she frequently claims to be the field leader. Throughout the series, she spends every moment she can in a bubble bath with her three rubber ducks, Umeyo, Umenosuke, and Umegoro. After learning of Sen-chan's feelings for her, she moves in with him, as of the crossover film Mahō Sentai Magiranger vs. Dekaranger.

As a child, Tetsu's parents were killed by an Alienizer named Genio, before Tetsu was taken off-world and raised by S.P.D. Due in part to this, he is initially distant from the other Dekarangers, but eventually befriends them.
In battle, Tetsu is a practitioner of the fighting style Justice Fist Accel Blow, a martial art that all Tokkyou officers train in to better handle their equipment and battle particularly deadly Alienizers. Unlike the primary Dekarangers, he wields the Bracerottle, which functions as an SP License, can double as a life-support system and a fire extinguisher, and allows him to perform a variety of specialized punch-based attacks.
During the events of the crossover film GoGo Sentai Boukenger vs. Super Sentai, Tetsu, among other veteran Sentai warriors, is recruited by Boukenger member Eiji Takaoka to help him rescue his allies and defeat the Time Demon, Chronos.

The Special Police Dekaranger, abbreviated as S.P.D., is an intergalactic police force that ensures all aliens abide by intergalactic laws, using advanced extraterrestrial technology, such as Deka Metal, which is used in the construction of their Dekarangers' suits. Their Space Prosecution Office headquarters is based on Planet Gowashichoru, which is affected by a form of time dilation called the Sion Morse effect, causing it to move faster than the rest of the universe. When the Dekarangers judge an Alienizer, an eight-month trial, which is the equivalent of ten seconds on Earth, takes place on Gowashichoru to determine the criminal's innocence or guilt in a particular crime.

Anubis, also known as "Boss" to several of his subordinates, is from Planet Anubis and is the tough-yet-honorable superintendent of the Space Police's Metropolitan Police, as well as chief of its Earth branch. While operating as a Dekaranger in his younger years, he earned a legendary reputation as "Hell's Guard Dog", due in part to his willingness to do anything to save those he cares about. Despite this, he displays feelings for his assistant Swan and panics whenever he hears she has an admirer.
During the events of the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Kruger investigated the alleged corruption of his superior Kight Reidlich, and was framed for murder and held captive for two years before his team rescues him in the present.

Alienizers

Space Criminal Alienizers is an umbrella term that S.P.D. gives to aliens that commit various crimes on Earth and other planets. Unlike most monsters in the Super Sentai franchise, many of the Alienizers pilot giant robots called Kaijuki, which are usually provided by Agent Abrella.

Agent Abrella

Rainian Agent Abrella is a bat-themed arms dealer from Planet Rain and an infamous figure in the intergalactic black market who is known for causing wars in seven galaxies, destroying billions of lives in the process. As his homeworld's name suggests, it is perpetually raining, forcing him to wear a special helmet that produces an artificial rainy environment to sustain himself on other worlds. After arriving on Earth, he offers his services, as well as Mechanoids and Kaijuki, to his fellow Alienizers for the right price. Initially staying in the shadows, Abrella gathers information on the Deka Base from clients who have successfully infiltrated it and escaped with their lives while planning to eventually realize his desire for a "world of...currency and crime". After eventually making his presence known to the Dekarangers and losing a Browgoul he intended to raise to them, Abrella starts taking their interference personally and launches a failed smear campaign against them. Following this, Abrella takes advantage of the Dekarangers' fight with the Alienizer Jellyfis to break four Alienizers out of prison and lead them in taking over the Deka Base. From there, he uses Deka Base Robo to go on a rampage, lure the bulk of S.P.D.'s forces to Earth, and uses their planetary forcefield against them. While the Dekarangers eventually retake Deka Base Robo and use the D-Bazooka to delete Abrella, he was succeeded by his pupil, Agent X, as of the crossover film Mahō Sentai Magiranger vs. Dekaranger.
In the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Kight Reidlich cloned a giant version of Abrella that he kept on Planet Highgord to help him fight the Dekarangers. However, Clone Abrella is killed by Dekaranger Robo piloted by Deka Break.

During the events of Mahō Sentai Magiranger vs. Dekaranger, Agent X pilots the succeeding model, Abotrex, before it is blasted into space by Magi Legend and the Deka Wing Cannon and destroyed by Magi King, Dekaranger Robo, Travelion, and Deka Bike Robo.
