Box art for Blaster Master Boy

Blaster Master Boy, known as Blaster Master Jr. in Europe, is the black sheep of the series. It was released as Bomber King: Scenario 2 (part of the Bomberman family), the sequel to a US game known as Robowarrior, but was localized in the United States as Blaster Master Boy in 1991. As such, it wasn't initially slated to be a part of the series and suffers deeply from it. Jason bears only a marginal resemblance to his first appearance and the gameplay is far more Bomberman than Blaster Master.

Though Jason is present, Sophia 3rd is not.
