Captain Marvelous

Captain Marvelous (キャプテン・マーベラス, Kyaputen Māberasu) is the young captain of the Gokai Galleon who transforms into Gokai Red (ゴーカイレッド, Gōkai Reddo). He was originally a resident of a planet invaded by the Zangyack Empire before turning to piracy, though he had no desire or motivation except to pursue the Greatest Treasure in the Universe, which he did not truly believe in at the time. While raiding a Zangyack treasure depository, he met Aka Red, who recruited him to the Red Pirates (赤き海賊団, Akaki Kaizokudan) while telling him to never give up if he wishes to obtain the Greatest Treasure. When the Red Pirates were wiped out in a Zangyack attack after being betrayed by their shipmate Basco ta Jolokia, Marvelous promised Aka Red to continue his quest for the Greatest Treasure. While he has no idea what the treasure is supposed to be, he makes finding it his only goal in life, eventually forming his own crew of space pirates whose members also share his ideal. Though he is the team leader, Captain Marvelous is an unpredictable sort of character who does reckless things to satisfy his curiosity, stating his actions as what any pirate would do in that particular moment, earning the ire of his crew, especially Don, at times. But his sense of responsibility as a leader is still very well intact, as shown when if his crew is ever in mortal danger, he would use his authority as captain and sacrifice himself, much like Aka Red did for him, to ensure their safety. He is much stronger than he looks as he is usually seen exercising himself by wearing a heavy bracelet while playing darts. His strength is displayed in a flashback in episode 12, where he rips the Zangyack tracking collar off Joe's neck, as well as in episode 21, where he rips the Heart of Hades right out of Ryuuwon's chest. He also has a rather hearty appetite. Before having Doc and Ahim join his crew, Marvelous' bounty was already established at Zagin 1,000,000 and raised to Zagin 1,500,000 when they get to Earth. This is eventually raised to Zagin 3,000,000 and then Zagin 5,000,000. After the death of Warz Gill, Captain Marvelous' bounty achieved the "Unlimited Reward" status, implying that anyone who takes on and completes the task can name any price that comes to mind. Captain Marvelous manages to defeat Basco to retrieve the five remaining Great Powers that the privateer had stolen.

During the events of Kamen Rider × Super Sentai: Super Hero Taisen, Marvelous abandons the Gokaiger and unites the enemies of the 35 Super Sentai teams as Dai-Zangyack, with the intention of stealing the Kamen Riders' Great Powers and claiming the Ultimate Treasure in the Universe (宇宙最強のお宝, Uchū Saikyō no Otakara). He battles and apparently destroys every Kamen Rider except for Tsukasa Kadoya, Kamen Rider Decade and the leader of Dai-Shocker, who likewise seemingly destroyed every Ranger except for Marvelous and Don. However, this ultimately turns out to be a ruse, as Marvelous and Tsukasa learned that the villains were planning on joining forces to defeat the Rangers and Riders, and hatched a plan to prevent this. The "destroyed" heroes were actually sent to another dimension to keep the villains from actually killing them, and were restored in time to battle the united villains and their Big Machine combat mecha. After their victory, Marvelous muses that perhaps friendship with the Kamen Riders is the real Ultimate Treasure in the Universe.

In Super Sentai Battle: Dice-O, Gokai Red can use the Gold Anchor Key to become Gokai Red Gold Mode (ゴーカイレッド ゴールドモード, Gōkai Reddo Gōrudo Mōdo) which later appears in a Special DVD called ''Kaizoku Sentai Gokaiger: Let's Do This Goldenly! Roughly! 36 Round Gokai Change!!''.
