"I didn't do anything to his brother!" - Tork Maddox

Hollowback is a Metal Maniacs car driven by Tork Maddox. It is a heavily-modified muscle car that looks like a mix of a 1970 Chevelle and a Dodge Challenger. Much of the engine is above the hood of the car.


Before Acceleracers

As shown in flashbacks, Hollowback was driven by Tork in the fateful race against Tone Pasaro in Synkro, resulting in his death.



Hollowback races against Synkro in the coastline, before being wrecked by Spine Buster.

Later, Tork Maddox joins the Acceledrome Crew with Hollowback along with Porkchop and Old Smokey.

The Ultimate Race

Hollowback was abandoned along with Spectyte in the Drone's headquarters.
