Todd Mendenhall's tank-like robot was simply unbeatable in Extreme Warriors. The sole two-time US finalist, it kept an iron grip on the Extreme Warriors title, using its scoop to bulldoze all who dared defy it. Panzer Mk 2 defeated the destructive Revolutionist machine by flipping it to take the first championship, before Panzer Mk 4 pulverized Tricerabot 3.0 in the second season's final.
Full-body spinners have always been popular in the States, and with machines like Bryan Nave's, it isn't hard to see why. With its entire body acting as a weapon, The Revolutionist dominated its matches, inflicting grievous damage onto hapless opponents like The Brute and Psycho Chicken. It took second place in Season 1 after Panzer Mk 2 flipped it, and made it to the heat final in Season 2, where it disarmed Propeller Head before falling victim to the pit.
Team Juggerbot was renowned for their success in Robotica, having finished as the runner-up twice with different incarnations of Juggerbot. Hoping their success would carry over to Robot Wars, Mike Morrow and his teammates festooned Juggerbot with paper bags and cardboard, and thus Tricerabot was born. Though it fell at the first hurdle Season 1, it returned as Tricerabot 3.0 in Season 2, and enjoyed much more success. With help from its newly added flipper, it knocked Rocky-Bot-Boa and Falcon Mark 2 out of the Grand Final on judges' decisions, before placing runner-up when the judges' decision in the final went to Panzer Mk 4.
David Temple's tough-guy attitude rubbed many people the wrong way; even the host expressed displeasure towards Team Falcon. Falcon lost in the first round in Season 1, but returned for Season 2 as Falcon Mark 2. Its second attempt proved much more fruitful after it defeated Nickelodeon Series champion Tyranabot in its heat final. It reached the second round of the Grand Final after Propeller Head blundered into the pit, but it went no further; Tricerabot defeated it on a judges' decision.
Jeff Cesnik's six-wheeled robot used its immense speed and pushing power to slam opponents into submission. In Season 1, it destroyed Mad Cow in the first round, before being bested by the eventual champion Panzer Mk 2. It returned in Season 2, but fell disappointingly early to Rocky-Bot-Boa.
Mike Regan's robot was often mockingly referred to as "Little Brute." However, it showed the Season 1 opposition that size didn't matter when it used it deceptively strong pushing power to reach the semi-final, where it was torn apart by The Revolutionist. It returned for Season 2, but drove into the pit in its second round battle against Unibite.
Another grand finalist from the highly successful Team Juggerbot, Chris Gattman's rambot showed its national pride with its fighter pilot garb. Rosie the Riveter lost in the first round of Season 1, but with its wedge and saw combination in Season 2, it pushed and rammed Darkness to reach the Grand Final, where it blew its chance against Panzer Mk 4 after carelessly driving into the pit.
The second half of this article is for robots that made one single attempt at the title. They are ranked in order of how far they reached in the Series, and also takes into consideration robots that they defeated and the circumstances of each victory.
Randy Eubanks's machine was the best performing newcomer to the US Championship in Season 2. Its spinning disc was devastatingly powerful, knocking out the fancied General Chompsalot in one hit. It reached the second round of the Grand Final after defeating Conquering Clown, but was immobilized by eventual Champion Panzer Mk 4.
Mike Konshak's robot showed that it was fully capable of taking punishment as well as dishing it out. Armed with a full body spinning bade, it managed an amazing comeback to defeat heat favourite The Revolutionist. Its only televised series loss in any competition came through driving into the pit against Falcon Mark 2 after causing considerable damage.
Douan Bingham's box shaped machine had a low chainsaw to cut its opponents' wheels, though its pushing power was put to better use in combat. It served up an easy knockout blow against The Bat, before losing a tight judges' decision against eventual runner-up Tricerabot 3.0.
Mike Flanagan's humanoid machine was pegged by many as a "fragilebot", a robot that was there purely to get smashed up by better competitors. Team Conquering Clown were determined to prove otherwise. Technical difficulties forced Conquering Clown to pull out of Season 1, but in Season 2, it dominated against Black Widow and Unibite 2.0 to reach the Grand Final. It held its own even against Destructive Criticism, only losing on a judges' decision.
