The search yields no character named "Mr. Tezuka" within *Marvelous Melmo* or its official media. Extensive coverage details Melmo, her brothers Totoo and Touch, Professor Waragarasu, Jiro, and Melmo's mother, yet omits any "Mr. Tezuka." Osamu Tezuka appears solely as the series creator, never as an in-universe figure. Comprehensive character lists, episode summaries, and media appearances confirm his absence from the narrative.
