Beat is a character who appears as a rival to the protagonist Zorori in the anime series Motto! Majime ni Fumajime Kaiketsu Zorori, having been created as an original character for this iteration of the franchise. He is an anthropomorphic fox distinguished by his orange fur, green eyes, thick eyebrows, and defined eyelashes. His most notable physical feature is his brown pompadour hairstyle, and he is typically dressed in a teal vest worn over a yellow t-shirt, complemented by red gloves, a red bandana, teal pants, a brown belt featuring his personal logo, and brown boots.

Operating as a self-styled jack-of-all-trades, Beat is a hot-blooded and highly righteous individual driven by a powerful sense of justice. His commitment to law and order is so intense that it manifests physically, with steam visibly erupting from his tail whenever he is in hot pursuit of a criminal. He is highly respected in his community for his dedication to helping others and assisting the police in their duties. Central to his background is his grandfather, Nick, who raised him and prepared him for adulthood at a facility known as the Beat Camp. Following Nick's unexplained disappearance, Beat took over the leadership of the camp, where he trains both children and adults. His parents are not mentioned in the available information about his past.

Beat's primary motivation and the core of his role in the story revolve around his complex relationship with Zorori. Upon discovering Zorori's identity as a mischievous bandit, Beat immediately set himself up as a rival, determined to capture him. He abhors criminals and evil-doers, and his initial worldview is rigid, perceiving morality in stark categories of good versus evil. This leads him to struggle with Zorori's actions, which often exist in an ambiguous moral space where he does not always behave like a true villain. Beat's goal evolved beyond simple capture; he became focused on reforming Zorori, aiming to turn him into an exemplary and law-abiding citizen, which aligns with his work helping the police rehabilitate criminals.

Throughout the series, Beat's dynamic with Zorori undergoes significant development, moving from outright hostility to a more nuanced rivalry. While early confrontations are marked by Beat's aggressive pursuit and attempts to impose strict discipline on Zorori, he eventually begins to doubt his initial judgment. Key events lead them to cooperate and team up, during which Beat gains a better understanding of Zorori's true character and comes to realize that he is not as bad a person as he once believed. By the end of the second season, Beat develops a grudging mutual respect for Zorori, which leads to more frequent collaborations when necessary, even if underlying tensions remain. This evolution forces him to loosen his rigid, black-and-white view of the world. In keeping with his mission to create a better world and spread happiness through his actions, Beat continues to appear as a recurring supporting character in Zorori's circle, including in later films such as Kaiketsu Zorori: Lalala♪ Star Tanjō.

To aid him in his self-appointed mission of apprehending wrongdoers, Beat carries a specialized array of anti-crime equipment in a sling bag. His tools include the Justice Rope for restraint, the Justice Gel for immobilization, the Super Scissors for various utility purposes, the Justice Ball for capture, and the Justice Hand for making arrests.
