In the original Angry Birds game, Bomb is the bird that can explode.
Bomb is the large black bird in the original flock. When the player taps the screen after launching him, he detonates, producing a powerful blast that destroys nearby structures and sends surrounding objects flying. This makes him especially useful against dense groups of pigs or sturdy materials.
The ability is tied to Bomb’s visual design: his black body, fuse-like detail, and explosive role distinguish him from the other original birds. Chuck, the yellow bird, accelerates rapidly when tapped, while Terence, the large red bird, relies mainly on his heavy impact rather than an explosion. Hal, the green boomerang bird, changes direction when activated.
Bomb’s explosive personality also became part of later Angry Birds storytelling. In The Angry Birds Movie, he is portrayed as a volatile but gentle character whose anger and fear can trigger literal explosions. That film characterization expands the game mechanic, but the core answer remains the same: Bomb is the explosive bird.
