The Disc of Doom (also known as the Floor Spinner) was a short-lived arena hazard that first appeared in Season 2 of Robot Wars: Extreme Warriors as well as the one-off series Nickelodeon Robot Wars. An altered version later made appearances throughout Robot Wars: The Sixth Wars, Dutch Robot Wars: Series 2, German Robot Wars and the second series of Robot Wars Extreme.

The hazard was initially located near the centre-left of the arena, where it was intended to fling competitors across the arena whenever they drove over it. This would interfere with their manoeuvrability, often disrupting attacks against opponents or simply causing them to lose control.


The Disc of Doom/Floor Spinner was a circular-shaped spinning panel built into the floor, similar to the Spinners used in the American robot combat show BattleBots. It was activated by a button similar to the pit release button, located on the upper-left side of the arena wall, though there were multiple instances where the spinner would already be active at the start of battles. The activation button initially took the form of a bumper labelled DISC (striped black and yellow in US Season 2/Nickelodeon, plain yellow in Series 6/Dutch Series 2/German Series), which was replaced by a yellow tyre in Extreme 2. All featured a hazard symbol depicting a spiral pattern, in a similar fashion to the symbols found on the pit release buttons.

The spinner had two major changes during its time in Robot Wars:

The first version of the Disc of Doom, used in the US and Nickelodeon series, had a spiral pattern on the spinner, along with teeth positioned along the spiral to tear the bottom of any competitors driving over it. However, this capability was never demonstrated, as the spinner rotated slowly and competitors such as Bunny Attack and Bigger Brother often got stuck on the Disc after being caught by the teeth. The Disc, nevertheless, also damaged Xylon's front wedge at the start of its battle while it was stationary. This version of the spinner made rare appearances in some battles from Dutch Series 2. The spinner was also known to have determined the outcome of some matches, with robots like Amok and Dragbot both becoming immobile by driving over it.

The second version of the spinner, used in Series 6, Extreme 2, Dutch Series 2 and German Robot Wars, had a cog pattern on the spinner. This version had no teeth attached to the surface and could only be used to throw competitors off-course. This was shown to have been effective on robots such as Stinger and 13 Black, which both lost control during their Heat Final match. However, for the most part, the spinner failed to make an impact on competitors with many surviving the spin. The spinner had an additional issue of wedge-shaped robots like Firestorm 4 and Dantomkia becoming wedged underneath the panel. By the end of Extreme 2, the spinner was removed entirely.

Conquering Clown 2 vs Unibite 2.0 None Unibite 2.0 Unibite 2.0 drove over the Disc and became stuck on the teeth. This allowed Conquering Clown 2 to slice into Unibite 2.0's sides and damage its wheels, which lead to Unibite 2.0 being unable to move on one side for the rest of the match.
Brawler vs Dragbot Dragbot Dragbot First immobilisation caused by the Disc itself. Dragbot became wedged under the trigger after slamming into it and Brawler. Later on, it drove head-on into one of the teeth while trying to push Brawler, losing mobility for a few seconds as Brawler in turn pushed it further over the edge of the Disc. Dragbot proceeded to take several hits from the Disc teeth as it tried to move away, eventually escaping before losing mobility again.
Buzz vs Tyranabot vs Xylon None Xylon Xylon drove over the Disc's teeth and damaged it's wedge at the start of the melee.

Appearances in Merchandise[]

The Disc of Doom (right) in the GBA version of Robot Wars: Extreme Destruction

Though rarely featured in merchandise, the Disc of Doom/Floor Spinner appears prominently in the Game Boy Advance version of Robot Wars: Extreme Destruction. It can found in all playable arenas (including the game's recreation of the Series 5-7 arena), activated by a yellow button and functioning similarly to its real-life counterpart. Unlike the real-life versions, the Disc features a unique yellow and black pattern possibly resembling cutting blades.


  • The Disc of Doom was the only major hazard to not be featured in any way on the Minibot arena sets.
  • The button trigger was pressed more times than the disc was actually used.
