Not to be confused with the Matryoshka-Bom.

The Bigbom[1][note 1] is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, bomb-based Badnik model created by Dr. Robotnik.


The Bigboms seem to be giant versions of the Bombs from the original Sonic the Hedgehog. They have large red and gray round bodies with red and blue buttons and a face plate with blue button that looks like their eye. On top of their heads are a fuse that can be ignited. These Badniks are also able to walk back and forth with a pair of mechanic legs.

In Sonic the Hedgehog CD, Bigboms appear exclusively in Metallic Madness Zone 2, where they are placed on paths near tight corners or in wide hall sections, where the player can move behind the setting. Bigboms usually walk back and forth, but upon noticing the playable character, they will run towards them while staring their self-destruction countdown. Like Bombs, Bigboms release six sparkling projectiles into the air when they explode. As the player has to advance through the Zone, kinky placements of Bigboms make it impossible to avoid them and dodging their projectiles can be tricky. Like Bombs, the player can also not destroy them.

The Bigbom is notably the only Badnik in the game that does not have a broken form due to age in the present and the bad future. It is also the only Badnik that appears in all time periods of the level it appears in, including the good future. Also, the Bigboms do not release Little Planet flower seeds upon their destruction.

Powers and abilities

The Bigboms are capable of self-detonation. When they detonate, they release harmful energy balls that scatter around them.
