Kaizoku Sentai Gokaiger (海賊戦隊ゴーカイジャー, Kaizoku Sentai Gōkaijā) is a Japanese tokusatsu series. Kaizoku Sentai Gokaiger is the 35th installment in the Super Sentai franchise, and the 23rd entry in the Heisei era. The series centers around a group of space pirates, known as the Gokaigers, who embark on a quest to discover the "Greatest Treasure in the Universe." On their journey, they confront the Zangyack Empire and encounter former members of Super Sentai teams from prior series.

The Gokaigers are space pirates who seek to find the "Greatest Treasure in the Universe". Initially acting out of self-interest, they gradually embrace their predecessors' roles as protectors of Earth and its inhabitants.

The Gokaigers wield special equipment with extraordinary features. They utilize the Mobilates (モバイレーツ, Mobairētsu) cellphones to transform into and summon mecha called Gokai Machines.^{[1][2][3][4][5]} Additionally, each of the primary members carry a cutlass-like Gokai Saber (ゴーカイサーベル, Gōkai Sāberu) and a flintlock-like Gokai Gun (ゴーカイガン, Gōkai Gan) as sidearms, both of which can be used with items called Ranger Keys to perform special Final Wave (ファイナルウェーブ, Fainaru Wēbu) finishing attacks such as the Gokai Slash (ゴーカイスラッシュ, Gōkai Surasshu) via the Gokai Saber, the Gokai Blast (ゴーカイブラスト, Gōkai Burasuto) via the Gokai Gun, and the Gokai Scramble (ゴーカイスクランブル, Gōkai Sukuranburu) via both.^[6][7][8]

Captain Marvelous (キャプテン・マーベラス, Kyaputen Māberasu) is the young captain of the Gokaigers. He is willing to use his authority to save his crew and civilians, even risking his life. Marvelous possesses superhuman strength achieved by playing darts with weighted bracelets.

Marvelous can transform into Gokai Red (ゴーカイレッド, Gōkai Reddo). While transformed, he dual wields the Gokai Saber and Gun.

In Kaizoku Sentai: Ten Gokaiger, Marvelous can transform into Cross Armor Mode, gaining the use of Gokai Galleon-themed torso armor, as well as Galleon Armor Mode, gaining combined usage of the other Gokaigers' Cross Armor Modes.^[9]

Captain Marvelous is portrayed by Ryota Ozawa (小澤 亮太, Ozawa Ryōta). As a child, he is portrayed by Tatsuomi Hamada (濱田 龍臣, Hamada Tatsuomi).

Joe Gibken (ジョー・ギブケン, Jō Gibuken) is the first mate of Captain Marvelous and the first to be recruited into the Gokaiger team. Originally a member of Zangyack's Imperial Special Forces, Joe was imprisoned after refusing to murder a group of captive children. He escaped imprisonment, and while on the run, Marvelous frees Joe from his tracking collar. Ever since, Joe has sworn loyalty to Marvelous. He created his own version of One-Sword Style: Soul Blade (一刀流ソウルブレード, Ittō-ryū Sōru Burēdo) to attack his enemies with his special attacks.

Joe can transform into Gokai Blue (ゴーカイブルー, Gōkai Burū). While transformed, he primarily dual wields a pair of Gokai Sabers.

In Kaizoku Sentai: Ten Gokaiger, Joe can transform into Cross Armor Mode, gaining the use of a quintuple-bladed, claw-like weapon on his right arm.

Joe Gibken is portrayed by Yuki Yamada (山田 裕貴, Yamada Yūki).

Luka Millfy (ルカ・ミルフィ, Ruka Mirufi) serves as the crew's lookout. Originating from a planet under Zangyack's control, Luka and her friend Cain took care of orphans until her little sister Lia's death. This led Luka to leave their planet to secure funds. While making ends meet as a thief, Luka comes across Captain Marvelous and Joe Gibken, who save her during a failed heist and offer her the position of reconnaissance expert. During her time as a Gokaiger, she acquires a collection of jewelry, which her teammates pawn off for local currency, much to her dismay. Despite her greed, she cares for her teammates, especially Ahim de Famille, whom Luka treats as a surrogate little sister.

Luka can transform into Gokai Yellow (ゴーカイイエロー, Gōkai Ierō). While transformed, she primarily dual wields a pair of Gokai Sabers, which she can either combine into a double-bladed weapon or use as a pair of extendable whips. Additionally, she has developed acute reflexes in combat, which she uses to make up for her relative lack of physical strength. Her training also enables her to spot nearby treasures and distinguish fake gems from real ones.

In Kaizoku Sentai: Ten Gokaiger, Luka can transform into the Cross Armor Mode, gaining the use of a quadruple blade launcher on her left leg.

Luka Millfy is portrayed by Mao Ichimichi (市道 真央, Ichimichi Mao).

Don Dogoier (ドン･ドッゴイヤー, Don Doggoiyā), nicknamed "Doc" (ハカセ, Hakase), is the ship mechanic, cook, and caretaker. Before the series, Don was a repairman whom Marvelous, Joe, and Luka sought out for help in fixing the Gokai Galleon. Impressed with Don's skills, Marvelous shanghaied him into his crew. Initially anxious and fearful, Don gradually becomes more confident and able to support his teammates throughout their adventures on Earth. Due to his background, he is dismissed by Zangyack and assigned the lowest bounty until he participates in freeing Marvelous from execution and defeats a leading Zangyack member.

Don can transform into Gokai Green (ゴーカイグリーン, Gōkai Gurīn). While transformed, he primarily dual wields a pair of Gokai Guns. Additionally, he relies heavily on stealth and trickery, with his clumsiness often resembling slapstick.

In Kaizoku Sentai: Ten Gokaiger, Don can transform into Cross Armor Mode, gaining the use of a double-barreled gun on his left arm.

Don Dogoier is portrayed by Kazuki Shimizu (清水 一希, Shimizu Kazuki).

Ahim de Famille (アイム・ド・ファミーユ, Aimu do Famīyu) is the pirates' diplomat who eases tension among her teammates and is the most fascinated by Earth culture. Prior to joining them, she was the princess of the planet Famille before the Zangyack Imperial Guard destroyed her home planet. While on the run, she came across the Gokaigers and asked to join them.

Ahim can transform into Gokai Pink (ゴーカイピンク, Gōkai Pinku). While transformed, she primarily dual wields a pair of Gokai Guns. During her early days with the Gokaigers, she had no martial prowess and a tendency to make a mess. By the time the pirates arrive on Earth, she became fully capable of holding her own in battle.

In the crossover film Gokaiger Goseiger Super Sentai 199 Hero Great Battle, Ahim can perform the Pink Double Attack Part 2 (ピンクダブルアタックパート2, Pinku Daburu Atakku Pāto Tsū) alongside Super Gosei Pink.

In Kaizoku Sentai: Ten Gokaiger, Ahim can transform into Cross Armor Mode, gaining the use of a quadruple-barrelled cannon on her right leg.

Ahim de Famille is portrayed by Yui Koike (小池 唯, Koike Yui).

Gai Ikari (伊狩 鎧, Ikari Gai) is the only Earthling of the group and a Super Sentai fan who was injured while saving a little girl from being hit by a truck. While recovering in the hospital, Gai was visited in his dreams by the ghosts of Mikoto Nakadai, Time Fire, and Dragon Ranger, who gave him the ability to become Gokai Silver (ゴーカイシルバー, Gōkai Shirubā) and access to their teams' Great Powers. Despite initially being denied membership in the Gokaigers, Gai's enthusiasm and bravery convinced them to let him join.^{[10][11][12][13]}

Gai possess knowledge of all the previous Sentai teams and the ability to fuse Ranger Keys using his imagination, having used it to create the Go-on Wings Key (ゴーオンウイングスキー, Gōon Uingusu Kī), the Gokai Christmas Key, and the Gold Anchor Key (ゴールドアンカーキー, Gōrudo Ankā Kī).^[14] Unlike the primary Gokaigers, he utilizes the Gokai Cellular (ゴーカイセルラー, Gōkai Serurā) to transform and summon his mecha, GouZyuJin.^[15] He also wields the Gokai Spear (ゴーカイスピア, Gōkai Supia) sidearm, which has a Spear Mode (スピアモード, Supia Mōdo) for performing the Gokai Shooting Star (ゴーカイシューティングスター, Gōkai Shūtingu Sutā) Final Wave, a Gun Mode (ガンモード, Gan Mōdo) for performing the Gokai Supernova (ゴーカイスーパーノヴァ, Gōkai Sūpānova) Final Wave, and an Anchor Mode (アンカーモード, Ankā Mōdo) for performing the Gokai Legendream (ゴーカイレジェンドリーム, Gōkai Rejendorīmu) and Gokai Legend Crash (ゴーカイレジェンドクラッシュ, Gōkai Rejendo Kurasshu) Final Waves.^[16] With the other Gokaigers, he can perform the Gokai Shooting Slash (ゴーカイシューティングスラッシュ, Gōkai Shūtingu Surasshu) Final Wave. Additionally, Gai can assume the following forms:

• Go-On Wings: A hybrid form based on Go-On Gold and Silver that arms Gai with two Rocket Daggers.
• Gold Mode (ゴールドモード, Gōrudo Mōdo): An armored form accessed from the Gold Anchor Key that grants increased offense and defensive capabilities at the cost of reduced speed and agility.^[17]

As of Two Kaizer × Gokaiger: The Tanuki-Charmed June Bride, he gains access to sixth Ranger Keys from the Go-Busters to the Zenkaigers by attaching the Gokai Tsuiker Unit (ゴーカイツイカーユニット, Gōkai Tsuikā Yunitto) to his Gokai Cellular.

Gai Ikari is portrayed by Junya Ikeda (池田 純矢, Ikeda Jun'ya).

The Ranger Keys (レンジャーキー, Renjā Kī) are mysterious items that were scattered across the cosmos after the previous Super Sentai teams sacrificed their powers to defeat the Zangyack Empire's first invasion wave. After forming the Red Pirates to gather them all, Aka Red gave them to Marvelous so he could find the Greatest Treasure. Stored in the Gokai Treanger Box (ゴーカイトレンジャーボックス, Gōkai Torenjā Bokkusu), the Ranger Keys can be summoned to a Gokaiger's Gokai Buckle via a thought-based teleportation system called the Key Road (キーロード, Kī Rōdo). The Keys allow the Gokaigers to transform, activate their weapons' finishers, and grant access a previous Sentai team's powers. After unlocking a Legend Sentai's Great Power, the Gokaigers can use the Ranger Keys to enhance their mecha and access unique powers. While the Gokaigers usually transform into a Sentai hero of their corresponding color and have primary personal Ranger Keys, the items are not specific to any of them.

In the film Gokaiger Goseiger Super Sentai 199 Hero Great Battle, it is revealed that past Sentai warriors can regain their powers by claiming their Ranger Keys. They can also infuse them with their team's Great Power, at the cost of their powers. However, deceased Sentai warriors such as Mikoto Nakadai of the Abarangers and Gai Yuki of the Jetmen still possess their powers.

During the events of the crossover films Kamen Rider × Super Sentai: Super Hero Taisen and Kamen Rider × Super Sentai × Space Sheriff: Super Hero Taisen Z, the Gokaigers gain Ranger Keys based on Kamen Rider OOO and six Metal Heroes, respectively.^[18][19][20]

In the film Tokumei Sentai Go-Busters vs. Kaizoku Sentai Gokaiger: The Movie, the Gokaigers seek out the five Phantom Ranger Keys (幻のレンジャーキー, Maboroshi no Renjā Kī), which are said to unlock the "Greatest Power in the Universe" (宇宙でもっとも巨大な力, uchu de mottomo kyodai na chikara). After joining forces with the Go-Busters, the Phantom Keys transform into Buddyloid Keys, which grant the Gokaigers and Go-Busters the use of Megazord Keys (メガゾードキー, Megazōdo Kī) so they can transform their mecha into those of past Sentai groups.

The Gokai Machines (ゴーカイマシン, Gōkai Mashin) are the Gokaigers' giant vehicles, all normally stored within the Gokai Galleon.

• Gokai Galleon (ゴーカイガレオン, Gōkai Gareon): Gokai Red's three-masted spacecraft that was originally Aka Red's vessel before it became the Gokaigers' base of operations. It is equipped with the Galleon Ram (ガレオンラム, Gareon Ramu), the Galleon Cannons (ガレオンキャノン, Gareon Kyanon), and several beam cannons on its wings.^[21] In Kaizoku Sentai: Ten Gokaiger, the Gokai Galleon was destroyed, though the Gokaigers used its remains to create the Gokai Galleon Key.
• Gokai Jet (ゴーカイジェット, Gōkai Jetto): Gokai Blue's Fighter aircraft-themed machine armed with beam and vulcan cannons as well as an energy cannon.^[22]

• Gokai Marine (ゴーカイマリン, Gōkai Marin): Gokai Pink's submarine-themed machine armed with a beam cannon, tracking torpedoes, and homing mines.^[25]

The Great Powers (大いなる力, ōinaru chikara) are varying special powers based on the Gokaigers' Sentai predecessors, which they gain by earning past Sentai heroes' approval.

The Space Empire Zangyack (宇宙帝国ザンギャック, Uchū Teikoku Zangyakku)^[a] are a race of aliens who have conquered and destroyed untold numbers of planets across the galaxy and plan to invade Earth for their emperor, Akudos Gill. While the first 34 Sentai teams foiled Zangyack's first invasion attempt during the Legend War (レジェンド大戦, Rejendo Taisen), Zangyack launches a stronger, second invasion led by the emperor's son Warz Gill from his chariot-like flagship, the Gigant Horse (ギガントホース, Giganto Hōsu). They initially see the Gokaigers as a minor nuisance until the pirates kill Warz, forcing Zangyack to prioritize stopping the pirates. Additionally, Akudos to come and oversee the invasion personally. Ultimately, the Gokaigers destroy a majority of the Zangyack fleet and kill Akudos, dissolving the empire and bringing their reign to an end.

During the events of the crossover film Kamen Rider × Super Sentai: Super Hero Taisen, an alliance of the Sentai teams' revived enemies and Zangyack's remnants form "Dai-Zangyack" (大ザンギャック, Dai Zangyakku) and join forces with Dai-Shocker to manipulate the Super Sentai and Kamen Riders into destroying each other. After the heroes fight back, Dai-Zangyack and Dai-Shocker combine their respective headquarters, the Gigant Horse and Crisis Fortress, to form the Big Machine (ビッグマシン, Biggu Mashin) mecha to destroy them, only for the heroes to defeat them and destroy the Big Machine with Rocket Drill Go-BusterOh.

In pursuit of this goal, however, he comes off as hysterical, lashing out when his missions fail. Warz especially shows anger towards Damaras, whom he knows Akudos sent to watch over him because his father lacks faith in him. Despite eventually learning of the Gokaigers' quest for the Greatest Treasure in the Universe, Warz initially refuses to focus on them. After being indirectly wounded by Captain Marvelous, Warz vows to kill the Gokaigers with extreme prejudice. Upon receiving the Great Warz (グレートワルズ, Gurēto Waruzu) war machine, Warz attacks Earth and overpowers the Gokaigers in battle before sending Barizorg to finish them off. Following Barizorg's death, Warz defies Damaras' concerns and returns to Earth to seek revenge, only to be killed by the Gokaigers via Kanzen GokaiOh.^[37][38]

He is ordered by Akudos Gill to accompany the latter's son, Warz Gill, and assist him as his second-in-command. Due to Warz's personality, Damaras frequently questions his decisions and expresses curiosity about the Gokaigers' reasons for being on Earth. To this end, he sends the Sneak Brothers to infiltrate the Gokai Galleon and learn the pirates' intentions before hiring Basco Ta Jolokia to eliminate the pirates. However, Damaras' efforts to convince Warz to prioritize crippling the Gokaigers' chances of earning Great Powers are hindered by Warz's single-minded focus on Zangyack's invasion of Earth. After the Gokaigers kill Warz, Damaras vows vengeance but allows Akudos to relieve him of his position and send him to the brig out of shame despite being able to easily escape. Nonetheless, Akudos gives Damaras a chance to redeem himself if he executes the Gokaigers personally. The latter forces Jolokia to help him overpower the Gokaigers while he captures Captain Marvelous, but a combination of Don Dogoier's successful rescue attempt and Jolokia's treachery leaves Damaras wounded before his rematch against the Gokaigers.

Following this, Bamick was forcibly converted into a cyborg by Zangyack scientist Zaien and had most of his memories erased save for his swordsmanship. While Barizorg eventually learns what happened to him, his programming makes him ignore the information. After Warz uses the Great Warz to overpower the Gokaigers, he sends Barizorg to kill them.
