Bombs are small robots resembling the stereotypical bomb. Possessing no limbs besides two stubby gray legs with long feet, they have a spherical red body whose upper hemisphere is covered in a gray metal layer. They also have an ignite wire on top of them.
As Sonic the Hedgehog and his allies walked through the Star Light Zone, a group of Bombs below the heroes noticed their presence and attempted to decimate them. However, everyone managed to escape safely.
