Bigbom

Bigbom is a Badnik that appears in Metallic Madness in Sonic CD. It isn't listed in any instruction manual, however it is referred to as "bigbom" in the game's source code. It is just a giant version of Bomb from ''Sonic the Hedgehog 1, and the projectiles he explodes into are also giant. They are placed on paths near tight corners where you need to go to advance the level, making them impossible to avoid and escape from their projectiles difficult.
