Mikachu (ミカチュー Mikachū) is a girl who works part time for Professor Banzo at the Strange Biology Institute. She acts as the player character in Game de Hakken!! Tamagotchi 2 and Hoshi de Hakken!! Tamagotchi.
Mikachu is timid, but cheerful and very enthusiastic about researching and raising Tamagotchi. She also makes mistakes a lot, but tends to play the straight man to Banzo in his sillier moments.
Mikachu was 16 years old and attending high school in Shibuya in 1996. Along with helping Banzo with his experiments, she also cleans and maintains the laboratory.
She was comforting Banzo one night on a bridge crossing the Sumida River when a UFO crashed into the water. The two brought it to the laboratory, and after discovering the plight of the aliens inside, they designed and built the "Tamagotchi HOUSE" (たまごっちＨＯＵＳＥ), a compact device for the aliens to live inside. She began painting some with unique designs and brought them to school with her, triggering interest from her classmates and sparking the spread of Tamagotchis around the world.
