- "This one worried us a bit, one hit from the disc could do some serious damage."

Retribution was a robot that attempted to enter Series 6 of Robot Wars. It failed to qualify for its only series, after breaking down during its qualifier battle following damage sustained from 13 Black and Kan-Opener.
Retribution was an invertible, two-wheeled robot painted dark blue and armed with a large horizontal spinning disc. The disc was made from steel, as was its rear armour (5mm thick according to the Team 13 Black website), and the weapon's outer rim was covered by a bicycle tyre when the robot was stationed outside the arena.
In its qualifier for Series 6, Retribution fought alongside 13 Black, Boudicca and Kan-Opener. After initially attacking Boudicca, 13 Black reversed into Retribution, hitting its side and leaving several holes through its armour after several more attacks.
- "We then reversed and went for Retribution, hitting it right in the side where we had planned (a bit lucky really!) we kept hitting them as much as we could, making some nice holes in the surrounding armour, Kan Opener joined in too and Retribution finally went into the corner and didn`t move, we took one more go at them just to make sure and made a deep cut into the rear armour which I think was 5mm steel."

Retribution proceeded to sustain damage to its power circuits from Kan-Opener as well, before driving into a corner and breaking down. 13 Black slammed into Retribution one more time, cleaving a deep gash through its back panel, before Retribution's damaged power circuits caused radio interference with 13 Black and Kan-Opener for the remainder of the battle. However, Retribution lost the qualifier anyway, and failed to qualify for the Sixth Wars along with Boudicca.
