Ganta Momochi is a supporting character from the television series Android Kikaider 01, appearing as a freelance photographer who claims to be a descendant of the legendary Kouga ninja Sandayu Momochi. He is depicted as a clumsy and somewhat bumbling individual who constantly carries a camera with him, driven by the ambition to capture a major news scoop or an exclusive photograph. Despite his persistent efforts, his attempts in this field are consistently met with failure. His role in the narrative is primarily that of a comic relief character, providing a lighter, more humorous presence amidst the series' more serious conflicts involving androids and evil organizations.

Within the story, Ganta is regularly referred to by the nickname "Ganmo" by the protagonist Ichiro (Kikaider 01) and another character named Akira, a label that visibly irritates him. This dynamic forms a key part of his interactions with the main cast. His presence in the series is limited to the earlier episodes, with his last appearance occurring in episode 19. After this point, he vanishes from the plot without any in-story explanation, simply ceasing to appear as the narrative progresses. He does not possess any notable superhuman or combat-oriented abilities, as his function is grounded in his ordinary human profession as a photographer and his unsuccessful pursuit of a story. An alternate spelling of his name is sometimes given as Gunta Momochi.
