Zachary Foxx
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, allowing him to fire blasts of energy with his left arm and giving 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 channeling of bio-electrical 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".
Foxx was voiced by veteran actor Jerry Orbach.
Shane Gooseman
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". Civilian senator Wheiner dosed the Supertroopers with the X-Factor mutagenic gas (a condemned, unstable compound), which he meant to speed up their mutation and to make them more powerful which it did, but it also 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 shape-shifting his body to adapt based on his situation or environment. Goose's implant supercharges his genetic bio-defenses, enabling them to react almost instantly, instead of minutes or hours, as would normally happen. This brings him close to the level of the rogue Supertroopers, and makes him the only one capable of going one-on-one with them in personal combat. His characterization is heavily inspired by Clint Eastwood. It is also noted that he is the only Supertrooper with compassion and imagination.
Niko
Niko is an archaeologist specializing 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. Niko's implant acts as a psychic amplifier, boosting her innate psychic abilities by adding power from the converted radiation into a psionic boost which can increase her range from simple tactile up to light years 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.
Niko was born on the failed colony world of Alspeth. After the destruction of her colony, she was found by Ariel and taken to the haven world of Xanadu where her psychic abilities were nurtured. At the age of 19, she left Xanadu to return to her people and joined the Galaxy Rangers. After the academy, she was accepted into the experimental Series-5 program. She was later assigned to the Series-5 Rangers as their mystic and archaeological expert, due to the number of missions they embarked on involving new cultures and varied belief systems.
Walter Hartford
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 communicate with and control special programs called 'tweakers', which appear as flying holographic computer-animated geometric shapes. 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."
Doc carries a Computer Diagnostic Unit; a compact computer which has advanced diagnostics and maintenance functions, along with sensory and computer linkage capability. The CDU acts as a focus for Doc's implant power, and also as a storage facility for his "tweakers" (Pathfinder, Tripwire, Firefly, Searchlight, Lifeline, and Pixel). His "tweaker" computer programs are part of his personality and offer capabilities far beyond any normal computer program, virus, or worm. His implant gives him control over his "tweakers" via simple verbal communication, and his "tweakers" give Doc control over any computer system.
Hartford, from the Island of Jamaica, was born to wealthy parents, and so he was educated in private school, topped off with Mrs. Abercrombies Charm and Finishing School. He left there to join the Ranger Corps after he signed up with some biochemical corporations to help them produce better computer programs, but found out that his skills were not being challenged.
