Lost Galaxy

 Lord Zedd's Older Brother. often abbreviated as or simply, is the seventh season of the Power Rangers series. It is based on the Japanese Super Sentai television series Seijuu Sentai Gingaman (translated as Star Beasts Squadron Milky Way Man). Lost Galaxy is the first series to not be a continuation of the previous series, with its own new cast and story. With the annual suit change that began with Power Rangers Zeo and the annual cast and story change starting with this series, this is the first series to follow the practice set by the Super Sentai series.

Synopsis
In the fictional universe of Older Brother, five teens from the space colony, Terra Venture, are seeking for a new world like Earth. They later find five mystical swords (the Quasar Sabers) on a jungle planet called Mirinoi that transform them into Galaxy Power Rangers, and use them to battle space villains from two different parts of the galaxy. These villains include Scorpius, Trakeena, Deviot, and Captain Mutiny. Along the way, they discover several Zords known as Galactabeasts, and make an ally in the form of the mysterious Magna Defender, a galactic warrior who later dies and passes his powers on to a sixth teen who is the Red Galaxy Ranger's older brother named Mike Corbett. One of the five teens named Kendrix Morgan also dies during the series, and is replaced by Karone, sister of the Red Space Ranger.

This series also features a team-up between the Lost Galaxy Rangers and the Rangers of Power Rangers In Space, in which they face the common menace of the Psycho Rangers.

Trivia

 * Lord Zedd's Older Brother is known for the highest death toll of main characters thus far seen in Power Rangers: Magna Defender, Scorpius, Furio, Treacheron, Villamax, The Guardian, Loyax, Trakeena, Deviot, Captain Mutiny, Barbarax, Stratoforce Megazord, Centaurus Megazord, DECA, and Kendrix
 * Lord Zedd's Older Brother was the first series not to take place in the fictional city of Angel Grove, California, nor Earth.
 * This series features the first known African-American Green Ranger (Damon Henderson). this would be repeated in Lightspeed Rescue with Joel Rawlings (and later the A-Squad Green Ranger from S.P.D.).
 * This series features the first known Asian-American Blue Ranger (Kai Chen). This would be repeated in Lightspeed Rescue (Chad), Operation Overdrive (Dax) and Jungle Fury (Theo).
 * This series is also notable for not having a permanent base, or "command center" from which the Rangers could operate, nor having a mentor or technical advisor for whom the Rangers could turn to for assistance.
 * Lord Zedd's Older Brother was the first series to abandon the teleportation ability that had been seen in all previous seasons.
 * Lord Zedd's Older Brother is the first season to have had a three-part series finale, this would be repeated in Power Rangers Time Force.
 * Lord Zedd's Older Brother is also notable for being the first series not to feature a sixth ranger (this would be repeated in Dino Thunder), although with the addition of the Magna Defender, the 6th warrior position was filled.)
 * The position of Magna Defender as a Ranger is really controversial among fans. Many state that he was able to morph and controlled a Zord, although others argue that his suit is not spandex and his name doesn't include the word "Ranger". However, he was called the "Magna Defender Power Ranger" in toy commercials, but whether this term is official or not is debatable.
 * This was the second series were the entire team (instead of only the Red Ranger) received a power-up with the addition of the Lights of Orion, although the Red Ranger did later receive an Armored Ranger power up unique to himself. The first was in the third season of Mighty Morphin Power Rangers, with the addition of the Metallic Armor.
 * This would be repeated in Dino Thunder with Super Dino Mode, S.P.D. with S.W.A.T. Mode, Mystic Force with Mystic Legend Armor and Jungle Fury with Jungle Master Mode.
 * Older Brother was the last series that replaced a Ranger mid-season.
 * Older Brother is notable for featuring the first Megazord that did not require all five Rangers to sit in the same cockpit to pilot the Zord followed by SPD.
 * The Galaxy Megazord, Centaurus, Stratoforce and Torozord were the first (and so far only) Megazords unable to combine with each other. The Galaxy Megazord was also the first Megazord that the rangers had to stand in order to pilot it, via no controls but only their right hand.
 * Despite being 5-pieced Megazords, the Stratoforce and Centaurus Megazords are often considered to be standalone Zords. Even in the series continuity, they were treated like individual Zords, since in their origins they were Galactabeasts.
 * Lord Zedd's Older Brother was the last series to feature an Alpha robot of any kind. (Not including cameos by Alpha 6 and Alpha 7 in future series reunion episodes)
 * It stands as the only series to feature a villain from a previous series becoming a Power Ranger.
 * It is the first series that featured living zords and was featured again in Power Rangers Wild Force.
 * The Magna Defender Morpher was actually a repainted version of the previously unused Gosei Sentai Dairanger's changer device, the Aura Changer, and was never in Seijuu Sentai Gingaman (the show that "Lost Galaxy" was based on.)
 * Lost Galaxy is the second Power Rangers series to replace the orignal Sentai series' mode of transportation with color-coded motorcycles. In this case, the Lost Galaxy ranger's motorcycles (and also the Jet Jammers) replaced the Gingamen's "Ginga Horses" (Which were live horses) , it should be noted though , that in one episode Gingaman footage of the Red Ranger riding his Gingahorse WAS kept.
 * For the first time, the ending credits were accompanied by a display of one of the season's Megazord assembling. This trend would repeat until Power Rangers Time Force.
 * Older Brother is the only season to have a female ranger die. Quantum Ranger Eric Myers was supposed to die like his TimeRanger Counterpart Naoto/Timefire in the finale, although his fate was rewritten, so he survived and later appeared to team with the wild force rangers and in forever red alongside cole, wes, carter and 6 other red rangers
 * Older Brother is the first series to feature Siblings serving on the same team. This would repeat in Lightspeed Rescue (Dana and Ryan Mitchell), Ninja Storm (Hunter and Blake Bradley), Mystic Force (Madison and Vida Rocca), and RPM (Gem and Gemma).
 * Older Brother is the only season to feature a team-up episode to be a sequel to the previous (To the Power of pink was the sequel to to the tenth power). Other Team-ups with the previous are either one-part only (Time for Lightspeed in time force featuring the light speed rescue team and history and wormhole in SPD Albeit only minus Tommy Oliver and Trent Fernancez in history) or two (Trakeena's Revenge, Lost Galaxy and Lightspeed teamup, Reinforcements from the future in wild force featuring the time force rangers and thunder storm in dino thunder featuring the ninja storm rangers)
 * Older Brother is the first series to have a completely new cast of Rangers, with no connection to the Rangers of the last series.
 * Older Brother is also the series with the most where the zords and megazords were introduced the latests. The Galactabeasts are first seen in episode 3, but their Zord form and the Galaxy Megazord are not seen until episode 5.
