Boss is one of main characters in Hamtaro. He is the self-proclaimed leader of the Ham-Hams.
He is a large cream and brown field hamster. He has dark green eyes. There is a nick in one of his ears. He wears a yellow helmet and carries a shovel.
He often tries to look like he knows everything, only to have it backfire in his face. He has a bit of a temper, but he is very dependable, courageous, and nice, even shy at times (especially around Bijou). Due to being a field hamster, he is more familiar with nature and is more independent compared to the other Ham-Hams. He has even developed a field hamster sense that instinctively tells him what kind of weather is approaching. However, he cannot deal with the sea as he is prone to sea sickness.
- Boss has a huge crush on Bijou.
- He is wild field hamster.
- He doesn't have an owner.
