Wherever there is life, there is a roar of justice!Hyakujū Sentai Gaoranger ("Hundred Beasts Squadron Roaranger" note gao is the Japanese word for roar.) is the twenty-fifth installment in the Super Sentai, airing from 2001 to 2002.A thousand years ago the evil Org spirits were fought by warriors backed by the Power Animals, but in the modern day Orgs begin to show up again. From the Animarium in the sky, the Power Animals choose five new warriors to fight them, and they're mentored by Animarium caretaker Tetomu and joined by one of the original warriors who was frozen in time.Refer to Power Rangers Wild Force for the Westernized version.
Humongous Mecha: The first Super Sentai to feature extensive use of upgrades. In fact, it was the first to introduce multiple peripheral mecha, imply their compatibility out of the default formations and put the potential to good use. Super Sentai used this concept on and off for several years, before adopting it consistently with GoGo Sentai Boukenger.
Mecha Expansion Pack: The other Power Animals served as upgrades to the Gao King by replacing the Gao Shark and Tiger (which formed the right and left arms respectively) or the Gao Bison (which formed the waist and legs). The Shark and Tiger also served as alternate parts for the Gao Muscle and Gao Icarus (along with the Bison for the latter). Since the Power Animals were interchangable, there were combined forms that were never used on the show or never had official names.
Gao King + Gao Elephant = Gao King with Sword & Shield
Gao King - Gao Shark + Gao Giraffe = Gao King Spear
Gao King - Gao Tiger + Gao Deer = Gao King Cross Horn
Gao King - Gao Shark - Gao Tiger + Gao Polar + Gao Bear = Gao King Double Knuckles
Gao King - Gao Bison + Gao Madillo + Gao Rhinos = Gao King Striker
Other Power Animals includes the Soul Bird (which serves as a power-up to any of the robots) and the rare Gao Panda (which never appeared on the show and was only available as a giveaway along with a bonus CD offered by Terebi-kun magazine in Japan). There was also a blue version of the Gao Ligator and a black version of the Gao Elephant, as well as several Power Animals that were never made into toys.
Red: The Blazing Lion, Gao Red! Yellow: The Noble Eagle, Gao Yellow! Blue: The Surging Shark, Gao Blue! Black: The Iron Bison, Gao Black! White: The Belle Tiger, Gao White! Silver: The Sparking Wolf, Gao Silver! Red: Where there is life, there is a roar of justice! Hyakujuu Sentai! All: Gaoranger!
Played with in Episode 17 is the middle of the Loki arc. He doesn't become GaoSilver until Episode 24.
The Gaorangers are Brought Down to Normal a grand total of three times: First in Episode 14 where Freezer Org's freeze attack froze the G-Phones and the Gao Jewels. Then in Episode 44 where Rasetsu activates the bug he had planted in GaoRed's phone. Then there's the penultimate episode.
Then there's the Wedding Dress Org who attacks brides and other women, forcing GaoBlack to impersonate as a bride.
Clock Org also seemingly sends four of the Gaorangers to Edo-era Tokyo. It was merely an illusion, however.
The friendly Monster of the Week for this series was Charcoal Grill Org, whom the Gaorangers were forced to Mercy Kill. It seemed it wasn't a true death though, as he's shown serving food to Futaro at the end of the episode.
The Smurfette Principle: After three straight pinks, the lone girl gets to wear a different color this time, making her the fourth female white ranger.
Alien Blood: Orgs tend to bleed green—the fact that Rouki bleeds red is a hint as to his true nature.
All There in the Manual: The Super Sentai Art Collection: Sentai Robo Edition illustration book includes a list of all 100 Power Animals (No, it wasn't just a a grandiose title). It has all the Power Animals that appeared in the show, including movie-only Gao Kong, audio drama-only Gao Panda, the animals that had cameos in the finale, and lots of unused picks, some of which were also illustrated and associated to formations.
Animal Mecha: In spades, and one of the instances where it's crucial to the plot.
The Atoner: Silver, once he's freed from the thousand-year evil.
Back from the Dead: Blue is killed in episode 30; Black, Yellow, and White follow suit in episode 31. They don't stay dead for long; after a short quest in the afterlife, they come back by the end of the episode thanks to a literal Deus ex Machina.
Tsuetsue and the three High Dukes also get revived in episode 47.
Yabaiba has... "Yabaiba!", meaning "This is bad!" while also a direct pun on his name.
TsueTsue's "Oni in, luck out!".note "Oni wa uchi, fuku wa soto!" This one is a pun on a traditional Japanese saying which is recited during New Year's time to attract good fortune, which is the exact reverse of Tsutsue's quote: "Oni wa soto, fuku wa uchi!" (Oni out, luck in!)
Chromatic Arrangement: The three High Dukes have colors corresponding to the RGB scheme: Shuten is red, Ura is green, and Rasetsu is blue.
Clip Show/Breather Episode: Episode 45. Features, apart from the Gaorangers (and Yabaiba) reminiscing about the series so far, GaoKing dancing and the episode ending with everyone in a hot spring.
Gaoranger vs. Super Sentai, while including plenty of new action scenes, doubles as a clip show for the entire franchise, as the veteran rangers tell the Gaorangers about Super Sentai history.
Code Name: In a strange departure from previous series, the Gaorangers refer to each other by color and have no knowledge of their comrades' true names, and so the audience only learns of them by the last episode (though the names are shown in the opening and a few moments throughout the series). Even Gao Silver's apparently real name turns out to be either a nickname or a codename.
Their names are occasionally given in the show itself, but only on a few occasions prior to the finale.
Curb-Stomp Battle: The Gaorangers' battles with Rouki. When he brings out Gao Hunter you can generally be sure that some Power Animals are going to be taken.
Did You Just Punch Out Cthulhu?: Strangely, a heroic example. The supremely powerful Gao God is killed by Orgs twice in series history, and was evenly-matched with the Org-controlled Gao King.
Golem: The Power Animals are more like this than actual mecha. They're spirit animals who inhabit material aspects created from the Earth itself. Their robot-like appearance is due to using metal ore deposits to make their skins.
The entire team's henshin call: "Samon! Supiritsu obu ji aasu!"
Heel-Face Turn: When Silver first showed up, he was possessed by the demon Loki and became a good guy after the other Gaorangers beat him. His mecha, the Gao Hunter, also does a literal heel face turn, as his face changed from an "Evil Mode" to a "Justice Mode".
Part of Charcoal Grill Org's backstory. When he saw that humans enjoyed his cooking, he took on human form and then lived to enjoy human's delight.
I Let You Win: Ura pulls one in the Rangers by letting them win against Orgs powered by the thousand-year evil spirit, then using its matured power to power himself up.
Innocuously Important Episode: Well, more of an Innocuously Important Scene. Rasetsu smelling Tetom's cooking and being distractedd by it doesn't just let the Gaorangers destroy the Monsters of the Week. Rasetsu's craving for it is ultimately responsible for Senki's creation.
Laser-Guided Amnesia: Red suffers from this in episode 8. He doesn't forget everything, just his time as a Gaoranger.
Late-Arrival Spoiler: vs. Super Sentai spoils a bit of Choujuu Sentai Liveman. Yuusuke is mourning not just for his friends who died in the pilot, but ALSO Kemp and Mazenda, not only spoiling their deaths, but also that Obular survived.
Meaningful Name: The Gaorangers' civilian names all contain the names of their animal.
Mega Neko: While all the feline Power Animals count, this trope goes solely to the Super GaoLion, bigger than most of the combined mecha.
Mid-Season Upgrade: Not only do the Gaorangers get new Power Animals as the series progresses, Yabaiba and Tsuetsue also get upgrades of their own... for a while at least.
Miko: Tetomu. Tsuetsue is promoted to this by the Highness Dukes near the end.
Milestone Celebration: To mark the series' 25th anniversary the Gaorangers join forces with a bunch of veteran Sentai members.
Mons: There's a reason they're called Hyakujuu "note Hundred-Beast Sentai. Several episodes revolve around receiving new Power Animals. And then it's revealed at the end that There are literally 100 Power Animals, most of which were still dormant. This includes Gao Peafowl and Gao Wallaby, which are as awesome as they sound.
Mood Whiplash: Pretty big-time. Episodes can typically begin rather light - then end up rather serious. Such as Quest 38, where Lion Tamer Org "tames" the Gaorangers and the Power Animals, showing off various combinations of the latter along the way; but ending with Futaro showing his true powers, and that he isn't merely a child.
Then there's a Zyuranger nod, an elephant whose head becomes a shield for GaoKing (homage to Guardian Beast Zyumammoth's head being Daizyujin's shield) while the rest becomes a sword with which GaoKing performs a lightning-charged slash to finish the monster (homaging Daizyujin's Dinosaur Sword Godhorn and his Super Legendary Lightning Cut).
GaoKing is a nod to Ohranger Robo. Avian forming back and head, leonine torso, bovine pelvis and legs, with blue and white mecha forming limbs. The main design difference is that GaoKing has the last two mecha as arms and the bovine mecha forms complete legs, whereas Ohranger Robo's leonine mecha is torso and arms, and the last two mecha are lower legs.
In vs. Super Sentai, Yuusuke is mourning not only for his two dead friends, but for Kemp and Mazenda, who died near the end of Liveman. In addition, Obular, who survived, doesn't have a grave. Doubles as a Late Arrival Spoiler.
Not What It Looks Like: White chances upon Red's wallet in episode 8 and assume the girl in the picture is his girlfriend. Turns out she's the wife of Red's boss when he was a veterinarian.
Palette Swap: Many Power Animals are slightly modified recolors of others, most notably Gao God's components being retools of Gao King's components. Thanks to the stacked retools, Gao God avoids being a blatant example.
Panthera Awesome: Usually, animal-themed Sentai have at least one large cat ranger in the mix. Here, we have two, Gao Red for a lion, Gao White for a tiger. Additionally, we have the Leon and Jaguar mecha for Gao God.
Psycho Rangers: Done in Quest 12 by an Org based on a photocopy machine. And later, a specialty of Duke Org Dorodoro - he made the Gaorangers fight their shadows, which they could not defeat without hurting themselves.
