Dora, the sizable pet cat belonging to brothers Taisho and Shosho, possesses notable physical strength—consistently depicted as large enough to carry the non-ambulatory Shosho across most adaptations. She debuted in the 1969 anime adaptation and recurred in later animated versions, though her prominence diminished in certain iterations. Within anime storylines, Dora frequently engages with feline-centric narratives, developing affections for Shippona, Akko’s cat. This dynamic occasionally prompts Akko to use her transformation magic, impersonating Shippona to interact with or gather intelligence from Dora. Her role shifts across media: while the anime integrates her into cat-focused subplots or the brothers’ escapades, the second Ribon manga run and Nakayoshi manga relegate her to a background presence during Taisho and Shosho’s mischief, detached from primary story arcs. In the Myu spinoff, Dora makes only a fleeting cameo during its initial phase, absent from subsequent installments. No origin story, personality details beyond her strength and Shippona interactions, or significant character evolution across seasons, films, or OVAs are documented. She remains a steadfast supporting figure anchored to Taisho and Shosho.
