Baio Nishizawa (西澤 梅雄 Nishizawa Baio) is the head of the Nishizawa Corporation in the series Keroro Gunso. Baio is Momoka's father and lavishes on his daughter as much as he can, though he will not give in to her in an arguments. Baio is also head of his own private security forces, both assigned to him and Momoka, though his seem to be the superior of the two. Despite being rich enough to not need to, Baio is an extremely strong martial artist, having defeated both Paul and Oka in tournaments before they would become part of his life (Paul as his family's butler and Oka as his wife). He is also a very strong tactical leader, said to be absolutely ruthless and cold-hearted. Unlike the rest of his family, Baio does not have a split personality (though one time Momoka actually got his by accident in an experimental accident as a third personality for a short time)
Baio literally means "plum male".
