G-Force was an American competitor that fought in Season 2 of Robot Wars: Extreme Warriors. Though it lost in the first round of its Heat in the US Championship, G-Force had more success the Tag Team Terror competition, finishing as runners-up with teammate Sir Force A Lot.
G-Force fought in the US Championship in Heat G against General Chompsalot 2 and Marauder. The battle was short, as G-Force only suffered a few hits from both robots before breaking down under pressure, sending it out of the competition in the first round.
G-Force also fought in the Tag Team Terror with Sir Force A Lot, and in the first round they fought also first round drop-outs of the main competition Snookums and loanerbot Bang. G-Force started out in the arena with Snookums, who pushed G-Force around a bit before tagging Bang. Sir Force A Lot also came out of its zone to help G-Force in pushing Bang (whose tyre had been punctured) onto the flames where Bang was immobilised. G-Force sat out as Snookums was hurled across the arena and flipped over by Sir Killalot, and Bang was pitted by Sir Force A Lot. In round 2, the team fought Texas Tornado and Mad Cow Bot. G-Force sat out at the start, where Sir Force A Lot and Mad Cow Bot were exchanging blows with each of their spinning weapons. Mad Cow Bot was then set alight, and Texas Tornado had been pitted by G-Force's partner, however Mad Cow Bot was still mobile, and G-Force strayed too close to Matilda's CPZ. Matilda's flywheel destroyed G-Force, leaving Sir Force A Lot to continue against Mad Cow Bot who took the battle to a judges' decision, who in turn put G-Force and Sir Force A Lot through to fight Black Widow and Rocky-Bot-Boa. Black Widow was shoved around by Sir Force A Lot, but G-Force had been pushed onto the flame pit by Rocky-Bot-Boa. G-Force then got its spike stuck in the arena wall and could only watch as Sir Force a Lot fought Black Widow and Rocky-Bot-Boa alone, but to no avail. As a result, G-Force and Sir Force a Lot were declared runners-up of the Tag Team Terror competition.
The team also competed in Robotica with The Kraken (not to be confused with the UK Series 7 competitor), which was basically an alternate version of G-Force with a new paintjob. G-Force also competed in the third and fourth North Carolina Robot Street Fight competitions where it was painted blue and armed with a flipper as well as the axes.
