Lucky is the main hero of Kyuranger. Transforming into Shishi Red (Leo), he uses supernatural good luck and his catchphrase "Yossha Lucky!" to win. He is secretly a space prince from Planet Kaien and a descendant of Orion. With his bright optimism, he unites all 12 rangers as their core leader.

Hammie (Chameleon Green): A sassy, sharp, and highly energetic space ninja. She can turn invisible using active camouflage and is quick to call out the crew when they act foolish. Spada (Kajiki Yellow): The sophisticated ship's chef who views cooking as a way to save lives. He constantly throws food metaphors into his speech and fights with a precise fencing style. Tsurugi Ohtori (Houou Soldier): An ancient, revived hero with fire-based cosmic powers. He has a massive ego, constantly calling things "Legendary!", but carries a deeply self-sacrificing heart. Their Dynamic: A mix of unique talents. Hammie provides stealth, Spada keeps everyone fed and grounded, and Tsurugi brings overwhelming, legendary firepower to the mix.

Garu (Ookami Blue): A fierce, loyal werewolf-like alien who treats the team like his pack. He fights with a wild, beast-like sword style and has endless physical energy. Champ (Oushi Black): A loud, hot-headed fighting automaton built like a heavyweight champion boxer. He is incredibly proud and serves as the raw powerhouse of the frontline. Their Dynamic: The ultimate heavy-hitting duo. They bring high volume, intense passion, and unstoppable physical strength to the frontlines, always eager to rush into the thick of battle.

Stinger (Sasori Orange): An aloof, quiet, and deeply serious lone wolf. He fights with a physical scorpion tail and hides a deeply caring heart beneath his cold exterior. Kotaro Sakuma (Koguma Skyblue): The youngest member. A brave, stubborn Earth kid eager to prove he can protect the universe. He can temporarily grow to giant size in battle. Their Dynamic: A strict but fiercely protective sibling relationship. Stinger acts as a mentor and older brother figure, constantly watching out for Kotaro's safety.

Shou Ronpo (Ryu Commander): The Supreme Commander of the Rebellion. He usually acts like a lazy, goofy old man who loves terrible puns, but he is secretly a brilliant, battle-hardened dragon warrior. Raptor 283 (Washi Pink): The ship's android pilot and coordinator. She is highly organized, professional, and prone to wild, romantic daydreams. She fights using mechanical wings. Their Dynamic: The operational backbone of the team. Raptor keeps the ship running smoothly and often has to scold or reign in Shou Ronpo whenever his goofy antics get out of hand.
