These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ensemble Darkhorse: Minion, along with his "brother," Overkill. Diesector and Taz Bot were also insanely popular if merchandise sales were anything to go by.
"Funny Aneurysm" Moment: Surgeon General's introduction in this fight qualifies as its builder died in a car accident a few years later.
The fights were still good, but the prevalence of pointless "filler" between those fights was probably what killed the show.
More Popular Spin-off: Borderline case, but this is the show that introduced basic-cable viewers (and producers...) to the people who would become the MythBusters.
Retroactive Recognition: Adam Savage, Jamie Hyneman and Grant Imahara were competitors before MythBusters (and before Imahara worked for Hyneman's shop). Hyneman and Savage - who had known each other in special effects circles for years - collaborated on a bot called Blendo, which was considered to be too dangerous for competition several times. Imahara built Deadblow, a popular and beloved middleweight bot that often dominated its weight class.
Older than You Think: Although BattleBots didn't air its first season until 2000, there were two pay-per-view tournaments (to test whether the show's idea was viable) the year before, and the whole thing has its roots in Robot Wars, which began in 1994 in the USA. The Robot Wars USA tournaments continued until 1997. In 1998 The BBC took over the "Robot Wars" name to produce the TV show fans are familiar with, and the next year BattleBots began.
Evil Cheese Wedge, a robot Comedy Central bought off eBay, decorated, and used in several filler shorts in the fifth season.
To some viewers, Carmen Electra.
What an Idiot: Common criticism for Carmen Electra being made a presenter by many fans. After Warhead (a robot designed by the team behind famed Robot Wars champion Razer) was defeated by Overkill in its final fight, Electra stated the team "Could really use some driving lessons", despite the fact that the Razer team was renowned for their driving ability, and that Warhead, despite being incredibly difficult to control due to the gyroscopic design of the weapon, had decimated every other robot it had faced due to its precision attacks.
