Bee is the small dog that Majin Buu encounters and adopts, along with Mr. Satan. The two form a genuine bond—Buu even plays catch with him—until a couple of gangsters shoot the puppy. Though Buu heals the injury, the incident enrages him so much that when those same thugs turn their guns on Mr. Satan, it triggers the creation of Evil Buu.
By the end of the Buu Saga, Mr. Satan is traveling the area with Bee when they run into Gohan, Piccolo, Goten, Trunks, and Super Buu. This stretch of the story reveals a softer, more protective side of Mr. Satan—he's genuinely concerned about keeping Bee safe while Vegetto goes toe-to-toe with Buu. After everything settles, Bee ends up living with Mr. Satan and Buu as part of their household. He briefly stays with Bulma and Trunks in Wrath of the Dragon, apparently borrowed from Buu for a few days.
The dog shows up again near the end of Dragon Ball Z and during Dragon Ball GT, noticeably aged but still around. In English manga releases, he goes by "Bay."
