The brothers are seen as leaders by their friends. They can be told apart through their appearance: one (known as Pichu Big) has a scruff of fur on top of its head while the other (known as Pichu Little) doesn't. Pichu Little is also more mischievous than his brother is.
The Pichu Brothers live in Big Town, a large city in Johto. They are known to get into mischief with their friends at their clubhouse.
One day, they spotted Pikachu watching them from a glass elevator. When he gets separated from the other Pokémon, the two help him get back to them by taking him on a series of adventures through the city.
Like most Pichu, they cannot successfully use Electric-type attacks without shocking themselves.
In the game Pokémon Channel, they star in their own adventure called Pichu Brothers in Party Panic.
