Smasher/Devourer is the secondary antagonist in the story (the first being Securitron).

From the description given in the album’s booklet, the Smasher/Devourer is a large robot with an “egg-like frame” and “its arms are actually weaponry for protection”: no further information on its design is given and what the machine really could look like is left to the imagination. It was originally created by humanity to serve as law-enforcement but was re-programmed by Securitron.

The song is filled with quite a few veiled Biblical references, attributing Smasher/Devourer as the savior of the insurgents following the protagonist, Edgecrusher in the sense that it will liberate them by killing them.
