Baba is a member of the cast of the Japanese variety show Pokémon Sunday, which focused on Pokémon-related sketches, games, and information. As a regular personality on the program, Baba was often placed in comedic and challenging situations for the entertainment of the audience. His primary role was that of a participant in the show’s many physical games, costume contests, and battle challenges, frequently being put to the test alongside other cast members such as Professor Akido and Handsome Yamamoto.

Personality-wise, Baba is portrayed as competitive, persistent, and prone to over-the-top antics. He has a strong desire to prove himself, which is a recurring source of humor on the show. In one notable running gag, Baba repeatedly disguised himself as various new guest characters, including a monster ball maker named Gantetsu, a cameraman named Genzou, and a Pokéthlon overseer named Kejime. Each time, he was subjected to increasingly difficult tests to prove his identity, only to fail and be dramatically revealed as Baba himself, much to the exasperation of the other hosts. This demonstrates a playful, trickster side to his personality and highlights his willingness to go to great lengths for a comedic bit.

Baba’s motivations are often tied to success and recognition within the Pokémon Sunday crew. He is shown to take Pokémon battles seriously, and on one occasion, after suffering a series of defeats, Baba vowed to regain his fighting spirit and reclaim his position as the strongest battling member of the group. This drive led him to undergo intensive battle training in a dedicated episode segment. His development is largely non-linear, rooted in the show’s comedic and variety format; he experiences both humiliating failures, such as being eliminated from a cosplay Grand Festival competition, and moments of determination where he seeks to improve his skills.

Key relationships include his interactions with the show’s primary hosts, particularly Professor Akido and Handsome Yamamoto, who often served as the straight men to Baba’s antics or as the judges of his various tests and impersonations. Other cast members, like special guest Yutti, were also his rivals in contests. The group dynamic was one of lighthearted camaraderie, where they would celebrate birthdays and participate in sketches together, even as Baba frequently became the target of the show’s challenges.

In terms of notable abilities, Baba’s skills were largely demonstrated through the show’s physical competitions and Pokémon battle simulations. He was competent enough in Pokémon battles to have once held a "Pokémon Battle Throne" on the show, which he later sought to win back. In a cosplay contest, Baba dressed as the character Zoey and used a Nyarmar's Iron Tail attack in a balloon-popping game, showcasing his willingness to physically perform Pokémon moves as part of a skit. The show also implied that his in-game avatar possessed powerful legendary Pokémon, as one episode summary noted that Baba had lost his Rayquaza in a battle.
