In his first appearance, the Bank Robber accidently robbed the Penguin Village Police Station instead of the Penguin Village Bank. Arale and Gatchan meet him who he tries to use as hostages. He is freaked out and runs away when he finds out that bullets do not hurt Arale and that Gatchan can eat his gun.
He appears again where he takes everyone in the Soramame Barber Shop hostage. When he fires at the police, Kurikinton criticizes his bad aim and Kurikinton shoots Gyaosu right in the forehead blaming it on the bank robber.
