Extinguisher is a heavyweight robot built by Quicksilver Robotics which competed in Discovery Seasons 4 and 5 of the BattleBots reboot.

It is a four-wheel drive, trapezoid-shaped robot armed with a 15lb hammer based on a fireman's axe. Its alternative weaponry came in the form of a vertical bar spinner, and in its debut year, a flipping arm. Extinguisher also sported an authentic fire engine siren inside the bot to entertain the crowd and showcase its theme, though this had to be removed for later fights.

In its debut year, Extinguisher struggled to find a rhythm, losing its opening match to The Four Horsemen before underperforming in a rumble against Rainbow and Double Jeopardy. Despite chalking up an uninspiring win against fellow newcomers BattleSaw, it was not selected for the Top 32, and lost an exhibition rematch against The Four Horsemen. In doing so, Extinguisher became one of the few robots to lose to the same opponent more than once in the same season.

For Discovery Season 5, the team upgraded Extinguisher to include a more refined chassis and armor setup, as well as new yellow tires with custom treads for better traction. Extinguisher also featured a more powerful drive system to allow speeds of up to 35mph, an actual fire extinguisher, and new steel wedgelets to get underneath opponents with more ease. With regards to its primary weapon, Extinguisher sported a new 35lb spike made from AR400 steel, called Forced Entry. This could be swapped out for an asymmetrical vertical bar spinner. Its authentic siren was also omitted from the bot. Despite these upgrades, Extinguisher did not do well in Season 5, winning only one fight and losing its two others by KO.

Extinguisher's look as it applied for the 2021 season.

Extinguisher also entered BattleBots: Bounty Hunters for a chance at a share of $25,000, but lost its only fight to Valkyrie in a destructive affair.

Despite applying for the season with six mix-and-match configurations teased for facing different opponents, Extinguisher was not selected to compete in Discovery Season 6.

Outside of BattleBots, Extinguisher is a regular competitor at Robot Ruckus events in Orlando, Florida, predating their BattleBots debut. In 2017, Extinguisher was a red, two-wheel drive robot with large wheels and a castor at the front. Its main weaponry came in the form of a large, curved scoop. However, it lost its first fight to Gruff.[1] It returned for the 2018 competition with a similar look but bearing a rust-colored scoop. However, it was easily dispatched of by Mammoth. Extinguisher appeared in its more familiar look in 2019, where it lost to Slap Box by way of a judges' decision.

Despite not being selected for the 2021 season of BattleBots, Extinguisher took part in the November 2021 Robot Ruckus event. Contrary to its relatively lackluster showings in BattleBots up to this point, Extinguisher impressed by beating Piranha and Mad Dog to reach the heavyweight final. However, it lost out to a recolored Big Dill called Banana Runt.

Extinguisher fought at the January 2022 Robot Ruckus event held during South Florida Fair. It had received several experimental upgrades including an anti-torque mechanism, which aimed to keep the bot steady as it swung its hammer. Extinguisher is known to have fought fellow BattleBots competitor Kraken, who punctured one of its lithium polymer batteries and caused smoke to fill the arena. In March 2022, the team confirmed their application for Discovery Season 7 of BattleBots.[2]

Robot History[]

Discovery Season 4[]

Extinguisher vs. The Four Horsemen

Extinguisher strikes Pizza.

Extinguisher takes shots from War.

Extinguisher's first fight was against a revamped version of The Four Horsemen. Extinguisher started off rather poorly as they missed with their weapon, which was also proving to be quite sluggish due a plate connected to the clutch that powers the weapon shrinking in the cooler temperature at the event. This undid all the fine tuning the team did prior to the fight. Extinguisher then took a hit from War but didn't suffer much damage. Extinguisher continued to move around the arena, occasionally firing its weapon but had very little success hitting The Four Horsemen apart from flipping Buttercup over.

Extinguisher then lost drive on one side as the outer shells for half the motors tied to the drive system shattered after shaking from the impacts and hitting the centers of the motors but Buttercup had stopped moving completely after receiving a shunt. Extinguisher was now driving in circles until it finally stopped moving. However, as the countdown began, Extinguisher got going and managed to survive to the end. A 2-1 split decision was awarded in favor of The Four Horsemen.

Extinguisher vs. Double Jeopardy vs. Rainbow

Extinguisher also participated in a rumble with Russian newcomer Rainbow and veteran Double Jeopardy. As the rumble got under way, Extinguisher missed with its weapon and instead took damage to its side from Rainbow's spinning bar. Extinguisher continued to fight but its weapon still didn't make contact, resulting in its drive taking severe damage. Extinguisher spent the rest of the rumble driving in circles having lost a drive chain earlier on. The judges awarded Rainbow a unanimous 3-0 decision.

Extinguisher vs. BattleSaw

Extinguisher's next fight was an untelevised was against twice rejected newcomer, BattleSaw. For this fight, Extinguisher went with a thick front wedge and its axe. This proved to be a good choice as Extinguisher was able to push BattleSaw where it wanted to, briefly causing smoke to appear from BattleSaw when it was near the screws. Extinguisher had little to do and nothing to fear as BattleSaw's weapon had been disabled so it continued to push the slow-moving BattleSaw into the arena barrier and the screws before BattleSaw finally stopped moving near the pulverizer. Extinguisher wanted to use its axe, but the receiver for its weapon was not working. Regardless, Extinguisher was still able to win by knockout as Battlesaw eventually stopped moving and was counted out..

Extinguisher vs. P1 vs. The Four Horsemen

Extinguisher was caught on fire and smoking.

Extinguisher also took part in an exhibition rumble with The Four Horsemen and P1. The rumble was off to a good start for Extinguisher as they were able to land hits on both The Four Horsemen and P1 with P1 losing its sacrificial spoiler. Unfortunately, Extinguisher was then lifted by P1 before losing a tire and being pushed onto the screws. Extinguisher escaped but was down to one side of drive and began smoking. To make matters worse, P1's minibot, Burnout, got under and ignited a LiPo fire inside Extinguisher with its flamethrower, which grew bigger and bigger as the match went on. Extinguisher's remaining drive stopped working and eventually lost the use of its hammer too. Extinguisher kept using its siren to keep the fire low as much as possible, but due to its battery power running out, the fire grew to such a size that the match was cut off early, bringing the rumble to a judges' decision, which ruled in favor of The Four Horsemen.

Discovery Season 5[]

Extinguisher vs. Perfect Phoenix

Extinguisher gets hit by Perfect Phoenix.

After its extensive upgrades, Extinguisher's first match was against Perfect Phoenix. Extinguisher was armed with its hammer and plow set-up, but started off very poorly as their box rush was side stepped and they ended up hitting the screws hard enough to disable their own drive system. Extinguisher had its paint scratched by its opponent as it was counted out, giving Perfect Phoenix the win by a rather easy KO.

Extinguisher vs. Gigabyte

Gigabyte rips off Extinguisher's left front tire.

Next for Extinguisher was a match against veteran Gigabyte. Extinguisher went with its hammer setup with the intent of firing the weapon once they got Gigabyte's weapon stopped. This did not go as planned as Extinguisher had changed its drive system, which lead to it failing a box rush and allowed Gigabyte to spin up. Consequently, Extinguisher was thrown onto its head but quickly righted itself. Extinguisher mistimed its next attack and lost its weapon support piece. Extinguisher then had its weapon arm twisted, rendering the weapon pretty much useless. Extinguisher was then thrown near the screws where half its drive was disabled as a result of the chain tensioner coming loose and the left corner of its wedge had been bent upward. Extinguisher could no longer move freely and was counted out, giving Gigabyte the win by KO.

Extinguisher vs. Gruff

Extinguisher rams into Gruff.

Gruff slams Extinguisher onto the base of the screws.

Fresh off a loss to Gigabyte, Extinguisher was now facing veteran Gruff, whom had also lost their previous battle to a well-driven Whiplash. Extinguisher was armed with its vertical spinner setup, which was painted to look like a dalmatian's fur. Extinguisher faced a rough start as they took flames directly from its opponent before being flipped over and pushed onto the screws. After another attack, Extinguisher was pushed back onto the screws, where it landed on its nose. Luckily, Gruff righted them but Extinguisher then took a hit that jammed its weapon with Gruff's lifting forks but Extinguisher was still upside down and unable to do anything. The match was then paused to try and separate the robots, though this was cut from the television airing. Consequently, during the process of freeing the two bots, Extinguisher's weapon belt had been cut, leaving them without an active weapon for the rest of the match. As the match resumed, Gruff's aggressive driving had worn out taken its toll on their drive and they were left to drive mostly in circles. Extingisher gave their opponent a final tap before Gruff was counted out, allowing Extinguisher to take a surprise win, and their only one of the season.

BattleBots: Bounty Hunters[]

Extinguisher vs. Valkyrie

Extinguisher charging at Valkyrie.

Extinguisher also competed in the Witch Doctor Bounty Hunters bracket, where it faced Valkyrie with its vertical spinner setup. The fight started poorly for Extinguisher, as the initial impacts between the two bots sent both of their wedges flying off. Though it pushed its Valkyrie back, this allowed them to get up to speed, and it wasn't long before Valkyrie damaged one of Extinguisher's front wheels. Struggling to drive, Valkyrie then tore that wheel clean off before doing the same to Extinguisher's other front wheel. Valkyrie attacked Extinguisher's rear tires until it was no longer able to move, and it was counted out, giving Valkyrie the win by KO.
