Triforian

Triforians are trifold beings from the planet Triforia, who exist as a fusion of three bodies.

Biology
Triforians appear indiscernible from Humans, at least outwardly. The most notable alien aspect of their biology is that they are actually three beings, each appearing to be identical siblings, fused into one body. They are normally joined together as one being working in perfect unison, but are capable of splitting into their three forms under certain circumstances, such as after taking sufficient amounts of damage. If unwillingly separated, the three forms are capable of merging, but this requires a complex process that can be painful to the Triforians and potentially be fatal. When split, Trey's three personalities were Heart, Wisdom, and Courage, but it is unknown if this is consistent throughout the species. While split, Triforians are unable to morph into Power Rangers, although this may be due to the unique makeup of their specific Ranger powers, which are molded to their physiologies.

Culture and society
Triforians are intergalactic peacekeepers, with at least one select member taking up the mantle of a Power Ranger and traveling to other worlds to help fight against evil forces, being familiar with other forces for good, such as Zordon of Eltar. It is possible that they held direct relations with the M51 Galaxy humanoids, as the Triforians protected the Super Zeo Gems, made from the Zeo Crystal that the M51 Galaxy humanoids guarded. Elite Triforians hold the title of lord, and have been seen acting as Power Rangers. They also appear to have some connection to a world in the Vica Galaxy, as Trey was sent to help defend it during the United Alliance of Evil's assault on known space. For an unknown reason, those selected to be Rangers attempt to hide their true identity, claiming it would cost them their powers, possibly done to prevent evil forces from tracking down their loved ones, implying that their Ranger duties are done anonymously.

Technology
The Triforians have access to advanced technology, including Power Ranger technology such as zords, although these were most likely provided to them, at least in a prototype form, by other sources, such as Ninjor or Zordon. At the same time, their Ranger technology appears specified to their physiology, especially in terms of their morphed forms, which has been seen being held in and activated through a staff rather than a conventional morpher. The Gold Ranger powers are known to need to be linked to a user who can actively use them, and will eventually fade away if not wielded by such a person. The Triforian zord Pyramidas was capable of interstellar travel, and was able to combine with other zords, such as the Zeo Zords, to form a larger Megazord.

History
In the past, Triforians began operating as intergalactic peacekeepers, working with other forces for good, coming to work with or at least know of Zordon at an unknown point in time. At another unknown point in time, they became the guardians of the Super Zeo Gems, made from a component of the Zeo Crystal, presumably before it was hidden on Earth's moon, and developed or received the Gold Ranger powers and zord. The Triforians, or at least just the Gold Ranger, were also targeted by a group of alien bounty hunters known as the Varox. Trey, a lord of Triforia, took up the mantle of Gold Ranger sometime before the last years of the 20th century. During the Machine Empire's attempts of conquering Earth, Trey took his zord and traveled to Earth to assist in the fight against the Machine Empire, utilizing his morphed state and Pyramidas to destroy a monster known as Wolfsbane, later returning whenever the Rangers were in danger, although did not wish to reveal who he was. Eventually, he was chased to the planet Aquitar by the Varox, who forced him to land under heavy fire. There, he was taken under the care of the Aquitians, and de-morphed in front of them due to the damage he had sustained in the assault. Weakened, he revealed who he was and asked to see Zordon.

He was sent to Earth, narrowly dodging a trap set by King Mondo of the Machine Empire, arriving in the ocean and being pulled to the coast by the Zeo Rangers. However, Trey soon split into his three forms, now unable to use his powers. They needed to transfer the Gold Ranger powers, and narrowly escaped another attack by the Machine Empire, but find that the candidate the Zeo Rangers presented, Billy Cranston, was unable to hold the powers. Trey's staff was attached to the Zeo Crystal to try to keep it powered until a new user could be found. Jason Lee Scott was soon chosen as the new Gold Ranger, and the three Treys readily transferred the power to him. The three Treys had to return to Triforia to reunite, but gave the Zeo Rangers the Super Zeo Gems before leaving. Later, Trey of Wisdom contacted the Rangers and sent them a zord known as the Warrior Wheel, which was soon joined by Pyramidas.

When Jason's body started rejecting the Gold Ranger powers, the three Treys were called back to Earth to reclaim them, but were still not reunified. With the help of Zordon, they use the staff to fire an energy beam into space, which ricocheted off of Aquitar and Triforia, and then finally hit Earth, the energy reuniting Trey and allowing Jason to give the powers back to him. Trey joined the other Zeo Rangers while they were battling King Mondo, who had grown giant-sized. Unable to summon any zords in time, Trey used his staff to make the Rangers themselves grow to a size that allowed them to battle and defeat Mondo. Two years later, the United Alliance of Evil launched an assault on known space. While the effects of this on Triforia is unknown, Trey was assigned to help defend a world in the Vica Galaxy, which was being attacked by Lord Zedd and Rita Repulsa. While he was captured, almost all of the evil forces were reduced to dust when Zordon's energy wave swept across several parts of space. Trey stood in confusion as Zedd and Rita, cleansed of evil and converted into Humans, happily danced away. After 2025, Triforians faced radical Varox attacks on Triforia. Trey was later present in a vision from an Andresian known as Orion and in the Legendary Battle against the Armada.
