The show is set in the future, some time after the year 2086, when two aliens from the planets Andor and Kirwin travel to Earth to search for allies against the expansionist Crown Empire led by the Queen of the Crown. In return for the help, the two aliens gave mankind construction plans for a hyperdrive device. After this key event in human history, interstellar travel flourished and a huge number of colonies emerged in distant star-systems. Alongside the growth of human activities in space, criminal activities also grew, and the new colonies required defense against various threats, including the Crown Empire. A group known as "BETA" (Bureau for Extra-Terrestrial Affairs) was founded to cope with these tasks, with a "Ranger" division being a part of it.
Zachary Foxx is the captain of the series 5 Rangers. He was seriously injured in a battle with a space Pirate named Captain Kidd and his entire left side was replaced with bionics which allow him to fire blasts of energy with his left arm and gives him extraordinary strength. Within Captain Zachary Foxx, the implant's function is simply to act as a power conduit: triggering the badge activates a sequence of events that supercharges his left-side bionics and enables either a boosting of the myomer muscles and tendons, or a channelling of bioelectrical energy through the bionic amplifiers to produce an energy blast of up to 16 standard carbine shots, which makes him capable of blasting a wall apart, spot-welding circuitry, or possibly punching through a ship's hull. He is married and a father of two. His wife's mind was kidnapped by the Queen of the Crown and is contained in a "psychocrystal"
Shane "Goose" Gooseman was genetically produced in a test tube as part of a government genetic experiment to create a group of enhanced mutant soldiers known as "Supertroopers". A civilian adviser dosed the Supertroopers with a gas meant to speed up their mutation and make them more powerful, but it had the side effect of making the Supertroopers more aggressive and mentally unstable. Goose was at the firing range at the time, and thus avoided the gas, thereby becoming the only remaining unaffected trooper. The other troopers had to be cryogenically imprisoned, but some escaped. Goose was given the option to avoid cryogenic freezing on the condition that he join the Galaxy Rangers and hunt down the escaped Supertroopers. His series 5 bionic implants allow him limited control over his body's molecules giving him the ability to heal, absorb energies, and adapt to various environmental conditions by temporary shapeshifting.
Niko is an archaeologist specialising in ancient cultures, and has innate psychic abilities. She carries a large gun and knows martial arts. Her series 5 implant boosts her psychic abilities and she can create shields, lift objects, and has clairvoyance. Ranger Niko's implant acts as a psionic amplifier, boosting her innate psionic abilities by adding power from the converted radiation into a psionic boost which can increase her range from simple tactile up to lightyears distant. She can also generate a shield of ambient energy which will dramatically drain her implant, but can be augmented by touching the other rangers and drawing power from them. This shield can defend against all forms of attack, but cannot be held for long. Throughout the series a romantic tension exists between her and Goose.
Walter "Doc" Hartford is a swashbuckling character who fights with a sword, a gun, and his fists. He is a computer genius who, along with the BETA Scientist 'Q-Ball', is responsible for most of the automated systems that the Galaxy Rangers use daily. His series 5 implants allow him to control any computer system through the use of "programs" which appear as flying holographic computer animated geometric shapes that he can communicate with. Ranger Hartford's implant produces the oddest effects- and they still cannot properly be explained. Commander Walsh puts it best: Doc Hartford, your implant makes you a computer wizard, able to conjure fantastic programs.

Waldo is the Ambassador from Andor and possibly creator of the Andorian hyperdrive. Very tall and distinguished, he is highly amusing when paired with Ambassador Zozo of Kirwin. The ambassadors are in very close contact with the Rangers and Commander Walsh at all times, and are friends of the Foxx family. Waldo is also a brilliant mathematician and engineer. He avoids violence, but will protect himself with a personal force field. However, if imprisoned or caged, he like other Andorians, loses control of his emotions and undergoes a de-evolution to a savage beast.

Zozo is the ambassador from the farm planet of Kirwin. The Kiwi are very much the opposite of the Andorians; whereas the Andorians are a highly technical society and coolly logical people, the Kiwi are very "down-to-earth" and emotional. Zozo is cheerful, loves a good time, and approaches most everything with a sense of humor.

Commander Joseph Walsh is the Rangers' commanding officer, as well as the head of BETA, (Bureau for Extra-Terrestrial Affairs) located in Beta Mountain. Brown hair (with grey at temples) brown eyes, assumed to be in his late forties. With Dr. Negata, he was in charge of the failed Supertrooper Project, of which Shane Gooseman is the only sane survivor. The Rangers are his friends, and Gooseman is something of the son he never had. He has been known to bend the rules for them such as when the Council of Leaders of the World Federation (typified by Senator Weiner) tried to put Goose behind bars for a crime he didn't commit. Walsh is something of a controversial character. It's implied in "Supertroopers" that he and Wheiner keep each other in check through a complicated web of mutual blackmail, and a series of "deals." Some of these "deals" involve bending the rules for his Rangers, but others might wind up harmful to them. He, Nagata, and Wheiner are the only ones who know about Shane being his "son".
Buzzwang, or "Buzz" for short, is an android whose biggest dream was to become a ranger, which he eventually did. He is Q-ball's go-fer, and in his spare time, he likes to breakdance. There are two versions of Buzzwang, most notably the pre-Tune-up and post Tune-up model, though the "personality" remains completely intact.

Captain Kidd is a Plitsky (a bird-like species) pirate. He was seen in "Phoenix" as a menacing, if bumbling, pirate that captured the ship transporting the Foxx family to Kirwin. Annoyed by the Queen's refusal to allow him to take the ship as a prize vessel and her decision to take control of the situation away from him, he turned on her. This of course, made Kidd a wanted man. He cut a deal to aid the Rangers in exchange for a "trade alliance" and continued freedom ("New Phoenix"). Other appearances have him helping BETA make first contact with the xenophobic Traash and taking possession of a memory bird (talking android birds that are used to store sensitive data) that had half of its circuitry corrupted. He also sold counterfeit starstones to the Crown, powering an armada that threatened to destroy Earth until Kidd let the Rangers in on how easy it was to destroy the brittle fakes. Consequently, Kidd became indirectly responsible for the destruction of much of the Crown fleet.
Nimrod the Cat a leonine humanoid villain wearing a multi-colored mane reminiscent of a rainbow wig. Nimrod was first seen in the episode "The Power Within". In the story Nimrod captures and deprives the Rangers of the use of their Series 5 badges, but using simple human skills, they pass his tests and prove themselves worthy of preservation.
The Queen of the Crown is the head of a vast and crumbling empire. We see instances of Crown conquests and atrocities in "Tortuna" where it is explained that she destroyed virtually all of Tortuna's population outside of a handful of domed cities. In "Queen's Lair," she enslaves the planet Wollcam and manufactures a gigantic gun that blasts a hole in the moon, attempting to ransom Earth for 5000 human lives. The Queen is an accomplished sorceress who often uses technology to make her considerable power all the more vile. Her psychocrypt and mind-link with the Slaverlords is but one example. In "Mindnet," she takes control of an experimental telepathy booster, which is later used in "Battle of the Bands" to control the minds of thousands of sentients attending a rock concert. Perhaps her most bone-chilling accomplishment was a machine that used Eliza's psychocrystal for power. It not only threatened to kill Eliza, but subjected Zachary to a form of mental torture.
