Wano Country Arc
A group of Beasts Pirates and Baboonmaru threatened a young girl named O-Tama when she ended up mentioning the Kozuki Family, and the komainu Komacchiyo attacked Baboonmaru to protect her. The two fought viciously, and Baboonmaru threw Komacchiyo into the Thousand Sunny. The Beasts Pirates told Baboonmaru to go after the nearby Monkey D. Luffy after Luffy attacked them, but Baboonmaru quickly became subdued when facing Luffy. Tama then offered Baboonmaru some kibi-dango, which tamed the baboon. Baboonmaru and Komacchiyo then took Luffy and Tama to the home of Tama and her master.
