In the Spanish dub (translation) of Power Rangers, there are major and minor changes. It also depends on the country it comes from. For those that don't know, much like English from the United States and English from England, Spanish from Spain and Spanish from Mexico, Cuba, Puerto Rico, South American, Central American and other Spanish-speaking countries, they are different too. All seasons have been dubbed by Mexico and Spain and some have been dubbed by Argentina. I am not sure if all seasons were dubbed in Argentina but I've heard a couple. The Mexico dubs serve for Central America and the Caribbean and most of South America.
I speak/understand/read Spanish and my parents are from Guatemala, I was born in the U.S.; I translated
Power Rangers Central myself. Some complained to why I would have a Spanish site, but many American web surfers forget the Internet is International and what is the point of dubbing a show in another language then?
Mighty Morphin Power Rangers = Power Rangers (the Mighty Morphin part was cut out)
The Putty Patrol became Patrulleros or Masillias, depending on the dub. Patrulleros obviously means Patrollers. And Masillias comes from Masa, which means dough.
"Morphin Time" has changed to metamorfosearse or sometimes, Morfosis. Metamorfosearse means metamorphosis.
Sabertooth Tiger sometimes called Tigre dientes de sable and Smilodon in Spanish.
From some episodes I've been able to see online, they changed some of the monsters' names, in recent seasons they kept their names the same, in English. Here are some that I could find:
King Sphinx = Rey Esfinge; Gnarly Gnome = Gnomo Lujoso (not sure of spelling or what Lujoso means); Pudgy Pig = Cerdo Rechoncho (Super Gross Pig); Eye Guy = Hombre Ojo (Eye Man); Terror Toad = Sapo TerroĆfico;
Chunky Chicken = Pollo Gordo (Fat Chicken); Knasty Knight = Caballero Manzarin (not sure of spelling or what Manzarin means); Pineoctopus = PulpopiƱa; Dark Warrior = Guerrero Negro (Black Warrior); Samurai Fan Man = Hombre Abanico Samurai; Hatchasaurus = Incubasaurio (mix of names, Incuba means Incubator); Jellyfish = Medusa (Medusa means Jellyfish); Grumble Bee = Queja Abeja (Complaining Bee); and Slippery Shark = TiburĆ³n Resbaladizo.Power Rangers Zeo = Power Rangers ZeoNot much changes--other than the basic translations, only ones worth mentioning is that the Gold Staff became the BastĆ³n Dorado (Golden Baton).
Power Rangers In Space = Power Rangers En el EspacioNot much changes to Turbo that I could find. In this season, Battlizer became Batallador, which is closer to the English word Battler.
Power Rangers Lightspeed Rescue = Power Rangers A La Velocidad de la LuzLost Galaxy became la Galaxia Peridad, which I can't find much changes. The name 'A la velocidad de la luz' which literally means 'At the velocity of the light.'
Power Rangers Time Force = Power Rangers del Tiempo
Basic changes like Time Ships = Naves del tiempo; Visual Scanner = EscƔner Visual; Quantasaurus = Quantumsaurio.
Power Rangers Wild Force = Power Rangers Fuerza Salvaje
Ferocity of the Blazing Lion became
Ferocidad del Leon Ardiente (Ferocity of Burning Lion) for Mexico and in Spain, it was
LeĆ³n de Fuego (Lion of Fire).
For Alyssa,
guile and agility of the Noble Tiger became
astucia y agilidad del Tigre Noble, for both Mexico and Spain which means the same thing. Funny enough, in Japan with the original Gaoranger, Noble Tiger was Belle Tiger, Belle means Beauty in French.
For Max, the
Surging Shark became el
TiburĆ³n Fugaz (Fugacious Shark) in Mexico and in Spain,
TiburĆ³n Emergente (Emergent Shark). 
For Taylor,
Soaring Eagle became
Ćguila Elevada (Elevated Eagle) in Mexico and in Spain, it is
Ćguila Planeadora (Planeadora has to do with planes but means flyer). Funny enough, in Japan with the original Gaoranger, Soaring Eagle was Noble Eagle.
For Danny, it remained the same from
Iron Bison to
Bisonte de Hierro for both Mexico and Spain. And Merrick was Lobo Aullador (Howling Wolf), in Japan it was 'Sparkling Wolf.
Power Rangers Ninja Storm = Power Rangers Tormenta Ninja
Storm Striker = Golpe de Tormenta (Hit of Storm); Hawk Blaster = Halcon de Fuego (Falcon of Fire); Lion Hammer = Martillo de LeĆ³n; Sonic Fin = Aleta Sonora (Sonar Fin);
Where the Squid had no name, I like that the Spanish dubbers gave it a name in
Taladro Calamar (Squid Drill); Bee Spinner = Abeja Destructora (Bee Destroyer); Sting Blaster = CaƱon Mantaraya (Mantaray Cannon); Nameless Spider became
Gancho AraƱa (Spider Hook); Star Blazer becomes
Rodillera Estrella (Knee Star); Ninja Firebird became
FĆ©nix Ninja (Ninja Phoenix).
Power Rangers Dino Thunder = Power Rangers Dino Trueno
Tyranno Staff = Tirano Vara (Tyranno Rod); Tricera Shield = Tricero Escudo; Ptera Grips = Ptera Garras (Ptera Claws); Raptor Riders = Raptor Movils (Mobile Raptors).Power Rangers Space Patrol Delta = Power Rangers Super Patrulla Delta
They had to change the word Space to Super to make SPD sense, because Espacio means Space in Spanish.
Canine Cannon = CaĆ±Ć³n Canino; Shadow Saber = Sable Sombra; Deltamax Strikers = Rayos Deltamax; Delta Runner = Delta Coche (Coche means car but literally it means Carriage); Uni-Force Cycle = Uni-Fuerza Moto (Moto is short for Motorcycle).
Power Rangers Mystic Force = Power Rangers Fuerza Mistica
Mystic Staff = Varas MĆ”gicas (Vara means rod, Varitas is usually used for Magic Wands); Mystic Force Fighters = PuƱos Fuerza MĆstica (Punos means Fists, gloves); Brightstar = Estrella (Star); Mystic Sprite = Hada Mistica (Hada means Fairy, but it can also mean Sprite).Power Rangers Operation Overdrive = Power Rangers Operacion Sobrecarga
Power Rangers Operacion Sobrecarga (Sobrecarga means Over-charge, but that is basically the same thing). These posters are from Argentina, Todoterreno means All-Terrain.
Drivemax Vehicles = Vehiculos Maxi; Flashpoint Megazord = MaxiFlash Megazord; Rescue Runners = Los Corredores Del Rescate; Overdrive Tracker = Explorador Sobrecarga (Overcharge Explorer); Drive Detector = Maxi Detector.
Power Rangers Jungle Fury = Power Rangers Furia Animal
I thought Power Ranger Jungle Fury was Furia Jungla but it is actually Furia Animal.
Blue Antelope Zord was Gazelle in Japan and became Gazelle again in Spanish:
Gacela.
Jungle Chucks = Nunchaku Animal (Animal Nunchuck); Jungle Mace = Furia Masa (Fury Mace); Jungle Fan = Abanico Animal (Animal Fan); Shark Sables = Escualo Sables; Jungle Tonfa = Tonfa Furia (Fury); Jungle Bo = Bo Furia (Fury Bo); Strike Rider = Turbo Moto.
I haven't seen the dub for RPM, so I don't know the changes.
For those that don't know, Rita came from the Japanese show Zyuranger and Lord Zedd is an original American creation. So when the Japanese created the castle (Bandora's Palace), they didn't have Zedd in mind. When Season 1 of MMPR started, I always wondered what the name of Rita's palace was, it clearly had the word 'Palace' in it but the show would always speed up the footage so we didn't see it. As you can see the arrow, the chamber is suppose to be in the center of the building, to our left. The Saban crew did really pay attention and made the chamber balcony like it for Zedd.
In the movie, the palace is reduced to look like a volcano stoop. It looks more like you expect Zedd's palace to look like if you only saw the balcony and not Bandora's Palace. The balcony looks more or less like the Zedd balcony on the show. The Zedd Palace in the movie looked like a prison. I thought some would find this interesting as well.
