Destructor

As Killbot bears down on the fearsome foursome, the snarl of an ancient terror is heard from the darkness of the fungoid tunnels...
Destructor
From a race and place unknown
One ton of hair, teeth, muscle, and bone
The savage lord of a bygone age
A broken hulk on a carnival stage
The people screamed, the whip cracked
Bloody lashes on his quivering back
A broken chain; pantaloons pissed
The sickening crunch of his pitiless fists
Through the murk of the stygian swamp
Came the sound of a thundering stomp
The wretched beast collapsed to the ground
As the Swamp Hag came to check on the sound
She gave him succor, she tended his wounds
He made a nest in a crumbling tomb
Every night he would come out to feast
Clawing at the graves of the newly deceased
Solo Digestor
The scent of blood perfumed the air
Into the catacombs
The monster lumbered, unaware
Spiked fist, iron claw
A sucker-punch to his powerful jaw
Clashing giants, thundering blows
Fermentor pitched in with a drum solo
Core breach; coolant aboil
Belching black smoke; vomiting oil
A mighty club to a cast iron hull
Transplanted brain liquified in its skull
System failure, tubes were blown
Two tons of steel dropped like a stone
Massive damage, Killbot was fucked
