The 808Z was an ancient steam train decommissioned and repurposed as Rapid's weapon storage compartment. Due to the war's increasing tenseness requiring more firepower, Rapid converted the 808Z into a combat vehicle. She commands from atop the train and safely dismounts once the train is in critical condition.
The 808Z has four attacks. Its standard attack is firing four missiles that spew out multiple fireballs upon collision. When up close, the 808Z thrusts its cowcatcher forward. Its special is opening its smokebox cannon and launching a large ball of coal that breaks into explosive shrapnel. The 808Z is able to undergo a non-self-destructive frontal attack as a counter attack.
