Movie
Description
Mikachu works part-time assisting Professor Banzo at the Strange Biology Institute. Timid yet cheerful, she displays fervent passion for researching and raising Tamagotchi. Though prone to occasional errors, she frequently acts as the straight man to Banzo's comedic antics. In 1996, as a 16-year-old Shibuya high school student, she helped Banzo conduct experiments and maintain their laboratory.

Her backstory revolves around witnessing a UFO crash into Tokyo's Sumida River with Banzo. After recovering the craft and learning of its alien occupants' crisis, they co-created the "Tamagotchi HOUSE"—a compact habitat device. Mikachu painted unique designs on these units and introduced them at school, captivating classmates and igniting the worldwide spread of Tamagotchi culture. She shares a friendship with Senatchi.

In the animated short *Tamagotchi Honto no Hanashi*, Mikachu appears alongside Banzo recounting the Tamagotchi species' origins. The story begins with her overwhelmed by caring for multiple Babytchi, prompting Banzo to explain how the creatures fled their home planet after an environmental catastrophe. This disaster occurred when Oyajitchi accidentally intoxicated their world with sake. Post-narration, Mikachu remains swamped by demanding Babytchi, resulting in a comedic clash where she forces Banzo to assist.

Beyond anime, Mikachu appears in multiple virtual pet releases. She greets users alongside Banzo in the Tamagotchi iD L's 15th Anniversary laboratory, a role repeated in the Tamagotchi m!x 20th Anniversary and Gift editions—sometimes attending Tamagotchi weddings. On the Tamagotchi Smart's 1996 Friends TamaSma Card, she and Banzo welcome the user's Tamagotchi upon card activation, while her hairstyle becomes an unlockable wig accessory.

In the PS1 game *Hoshi de Hakken!! Tamagotchi*, Mikachu stars as the player character. After crash-landing on an island with Banzo, she explores to locate and collect all 94 Tamagotchi species. Gameplay involves nurturing them, enabling social interactions, and managing breeding.

She also features in the instructional video *Kind & Polite! Tenshitchi's Official Training*, observing Banzo explain the Tamagotchi Angel device. She participates in drawing tutorial segments and introduces Angeltchi during a "Prayer Hour" demonstration.
