"Will this plumb the depths or torpedo the rest?"
— Jonathan Pearce

Sub-Version was a robot that was first entered by the Submarine Service in the Forces Special of Robot Wars Extreme: Series 1 to celebrate the centenary of the Submarine Service. It reached the second round of the Forces Special, where it lost to Mega-Hurts. An improved version of Sub-Version, known as Sub-Version 1.1, also fought in The Seventh Wars, but it was eliminated in the first round after being pitted by Trax seconds before the fight ended.



Sub-Version in Extreme 1

Sub-Version, and by extension Sub-Version 1.1, was a black robot designed to resemble a submarine, complete with a periscope that acted as a self-righting mechanism and a crow's nest complete with a uniformed Action Man figure resting inside. Its weapons were a pair of pneumatic spikes at the front and a small cutting disc at the rear.


Sub-Version originally attempted to qualify for Series 5, where it faced the fellow Scottish Corkscrew in the qualifiers.[1] However, Sub-Version lost the battle, and did not qualify for the Fifth Wars. Sub-Version 1.1 would later successfully qualify for the Seventh Wars.

Shockwave vs Sub-Version

Shockwave pitted by Sub Version

Sub-Version fought in the Forces Special. Its first match was against Anvil of the R.A.F. and Shockwave of the Police. On "Activate", Sub-Version rammed into Anvil, however the spikes were too high to hit it. Sub-Version was then attacked by Sergeant Bash, which was in the process of moving to another CPZ, but Sub-Version was not damaged. Sub-Version then released the pit just as Anvil pushed Shockwave onto the lip. Sub-Version then pushed Shockwave fully into the pit, eliminating the Police team from the competition. Sub-Version and Anvil then qualified for the next round.

"We're going to beat them into sub-mission!"
— Petty Officer Dave Robson of Team Mega-Hurts on Sub-Version
Sub-Version vs Mega-Hurts

Sub-Version breaks down against Mega-Hurts

In its next battle, Sub-Version faced Mega-Hurts of the Navy. The two robots attacked each other, Mega-Hurts being the quicker, but in the early stages, Sub-Version being the aggressor. It used its disc to attack Mega-Hurts, but the spikes didn't work. After a while, Sub-Version broke down and was pitted by Sir Killalot, but not before the captain doll was axed out of the crow's nest by Shunt.

Trax pits Sub-Version 1.1

Sub-Version 1.1 made its main UK series debut in Series 7. Its first battle was against veterans The Steel Avenger, previous competitors Shredder Evolution, and newcomers Trax. Sub-Version 1.1 started by taking a piggy-back over Trax, before being hit by Shredder Evolution. It then retaliated towards the spinner, but it was able to avoid Sub-Version 1.1. The two robots clashed again, being separated by The Steel Avenger. Trax then got under Sub-Version 1.1, drove it to the arena wall, and nearly flipped it out. Sub-Version 1.1 nearly made the mistake of driving into the pit after opening it. It then drove onto the flame pit to attack Trax. With just two seconds remaining, Trax pitted Sub-Version 1.1, eliminating it from the competition.
