Rainbow was a heavyweight robot built by Russia's Team Unicorn, which competed in BattleBots World Championship IV.

The robot was heart-shaped, two-wheel drive and invertible, armed with a rainbow-colored horizontal bar spinner driven by a large brushless motor and belt drive. Although the primary weapon could reach a deadly speed, it struggled to cause damage to well-armored machines, largely due to its weapon belt being too tight and suffering issues with their speed controllers. Debuting in the fourth season of the show, Rainbow won two matches, including a rumble and a knockout win over Nelly The Ellybot, but failed to make the Top 16 following a convincing loss at the hands of Yeti.

Rainbow was originally called Pinkie Pie (Russian: Пинки пай) featuring characters from the TV show My Little Pony on the top armor panel, which were hand-painted by the team. Despite competing under this guise in Russia and India, due to copyright issues, the name and top panel artwork had to be changed to fit the new name.[1] As such, Rainbow was weighed ahead of filming without its Team Rainbow artwork, which was applied by Karina Khatkevich and Daria Antipova ahead of their official photos. The original version of the robot weighed just 198lbs, but was upgraded to fit the 250lb limit ahead of BattleBots.

Rainbow was originally supposed to be the first HyperShock Approved team, but this team sponsorship fell through due to issues relating to shipping parts to Moscow.

"Technically Rainbow was the first team we tried to sponsor. Didn't quite work out. Turns out you can't ship industrial hardware into Moscow...we tried to ship them a box of stuff and it got stuck in customs in France."
— Kyle Awner on HyperShock's attempts to sponsor Team Rainbow

The team have not returned to BattleBots after World Championship IV, with the COVID-19 pandemic impacting almost every international team during the two seasons which followed. Despite this, the team have remained active within the Russian scene.

Outside BattleBots[]

Under the team name Energy Robo, they also entered the Chinese robot combat show Clash Bots with a rear-hinged flipper called Energy Bomb.

Rainbow returned in October 2023 under an all-female team called Energy Girls, for the Russian live event Bitva Robotov.[2] This team consisted of captain Zoya Sudakova, Valeria Orlova, Alina Bektasheva and Sasha Kravchenko. The robot was subsequently renamed Iron Wind.

World Championship IV[]

Rainbow vs. Nelly the Ellybot

Rainbow's KO hit.

Rainbow's first match was against fellow newcomer Nelly the Ellybot. When the match began, Rainbow's weapon got up to speed and began to attack Nelly the Ellybot's wedge, causing minor damage. Rainbow continued to attack and tore into the face of Nelly, leaving Nelly the Ellybot's left googly eye inoperable and sending one of Nelly the Ellybot's ears flying. Rainbow continued its assault and tore off the hammerbot's right eye completely. However, Nelly the Ellybot was still mobile so Rainbow went after the other eye, ripping it off and damaging the face further. Nelly the Ellybot showed very limited movement after this attack, so Rainbow delivered a final hit which also dislodged its own weapon belt. Nelly the Ellybot was counted out, giving Rainbow the win by KO after 1:05.

Rainbow vs. Extinguisher vs. Double Jeopardy

Rainbow's second match came in a rumble against Double Jeopardy and Extinguisher. When the fight began, Rainbow was able to spin up their weapon and damage Extinguisher while also avoiding the latter's hammer. After a hit, Rainbow's weapon struggled to get up to top speed, but was able to cause minor damage. While Extinguisher and Double Jeopardy were losing mobility, Rainbow mostly stayed away, trying to get their weapon going again. Time ran out with only Rainbow showing true translational movement, so the judges awarded Rainbow a unanimous 3-0 decision.

Rainbow vs. Yeti

The aftermath of Yeti's KO shot.

Rainbow's next opponent was Greg Gibson and Yeti. Unfortunately, the team was unable to repair its weapon in time, forcing Rainbow to fight with its bar barely functioning. As the match began, Rainbow was immediately on the retreat, trying to spin up its bar weaponry. Rainbow took a big hit from Yeti which cracked part of their rear armor, dislodged their top plate, and flipped the robot over. Rainbow started smoking heavily as a result from its batteries being ruptured inside. Despite being invertible, Rainbow was no longer moving and was counted out, giving Yeti the win by KO in under a minute. Despite a positive 2-1 record, Rainbow was not selected to advance to the knockout tournament.
