Bo Suzuki (Bo-chan) (ボーちゃん) is one of Shin-chan's friends and classmates from the sunflower class, he is 5 years old and born on September 10, 1992 in Kasukabe. He seems slow and expressionless, but is actually quite smart and has an interest in artistic, adult-oriented things. He loves to collect various kinds of stones, and investigating urban legends and various mysterious objects such as UFOs. He has his own place where he says the rarest stones in Japan can be found. He often surprises his friends with his insight, though he speaks quite slowly. He always has a trail of mucus running down his nose and can perform various tricks with it. Bô-chan always volunteers for the role of pet dog or cat when the group plays house. After the nursery he likes to go to a Kasukabe store in which tatami is made, he loves to see how they do it.
He has a sister named Nizu Suzuki. He is a functionally slow-speaking boy who is passionate about oddly shaped rocks. Like his interests, he's very odd and mysterious, which can sometimes be useful in certain situations. His mother has appeared only once in the manga and his father (ボーちゃんのパパ) has never appeared.
He is a member of the Kasukabe Defense Organization.
