Saint Hero Robin Hood, initially called Robin God, possesses striking blue hair and a distinctive star marking on his forehead. This visual signature grows more pronounced across Wrestler Gundan merchandise. Originating in the Wrestler Gundan franchise, the character first appeared on Gamura Twist gum and Ramen Bar snack stickers before expanding into wider media.

The character's story unfolds across two distinct anime series. "Go! Wrestler Gundan" features Robin Hood embroiled in earthly wrestling conflicts. The narrative then escalates dramatically in "Wrestler Gundan <Ginga-HenSeisenshi Robin Jr.," rebranding him as "Holy Warrior Robin Jr." for the Galaxy Saga. This sequel relocates the action to cosmic battlefields, positioning Robin Jr. as a central figure in interstellar warfare across its 50-episode run.

Merchandise charts the character's visual journey. Early sticker collections place Robin Hood among the Wrestler Corps, utilizing double or triple-layered seals to depict alternate forms or power states. Subsequent "MARK II" lines evolve into a "Plate & Seal" system, featuring character art on sturdy card-like plates. These plates often showcase power-up or power-down transformations, hinting at narrative progression. The final merchandise release, "Gamura Twist Final Ring," presents redesigned versions of classic characters, including Robin Hood.
