The Antweight Championship of Robot Wars Extreme: Series 1 (referred to onscreen as the Antweight Melee) was the first Antweight Championship, held during Robot Wars Extreme: Series 1. Shown in Episode 15, it was the first ever televised battle between antweight robots weighing 150g or under, and took place in a miniature version of the Robot Wars Arena. Seven competitors fought together in a single melee to determine the inaugural Antweight Champion.
Legion split as the battle began, one half attacking Little Nipper, the other Anty B, but with little success. Combat Ant's spinning disc struck Pants, sending it flying, as Little Nipper flipped itself and the half of Legion attacking it. As the robots converged, Combat Ant's weapon struck Pants twice, throwing it over and then out of the arena.
"Who's that that's gone out of the arena completely - the mini arena? I think it was Pants that went flying out!"

During the struggle, one of Anto's wheels had broken off. As Little Nipper pushed one half of Legion around, Combat Ant then drove over the Floor Flipper, causing it to activate. However, at the same time, the Flipper lifted an approaching Anty B upwards; Anty B landed over the edge and fell into the space containing the Flipper mechanism, eliminating itself from the battle. Combat Ant then took Anto's other wheel off, leaving it immobilised apart from its flipper.
"...we've got a wheel come off as well. It's all happening out there! Under pressure from Combat Ant... Anto has lost a wheel."

One half of Legion also appeared to be immobilised, as Little Nipper pushed Razzler into the pit release. Razzler managed to escape and pushed against Combat Ant, but was unable to use its crusher. Combat Ant and Little Nipper then teamed up against Razzler, pushing it around, but unable to cause damage. The half of Legion that was still mobile drove over the floor flipper, and was pushed off the ramp the flipper was now creating (due to Anty B) by Little Nipper, but it managed to right itself. Razzler pursued the remaining Legion twin, but in doing so exposed itself to Little Nipper, who pushed it down the pit. The three remaining robots met in the middle of the arena, and the remaining half of Legion tried to attack Combat Ant, but it was sent flying by its opponent's disc, which tore its flipper off.
"...we've got part of Legion... OH! Have we got part of Legion any more, spinning up into the air? I don't think so!"

Remarkably, Legion was still mobile and came back on the attack, as Combat Ant tried to use its disc on Little Nipper, who pushed it away with help from the Legion twin. Combat Ant drove away as Little Nipper momentarily got stuck on the floor flipper, moments before Cease was called. The judges were called upon to make a decision, with Combat Ant, half of Legion, and Little Nipper still mobile, while Anto continued to flip at thin air in the corner. The decision went in favour of Combat Ant, whose performance left Julia Reed especially impressed with its capabilities.
"I had no idea something that small could do that amount of damage! Now, I reckon if we had a robot like that in the real Wars, it would do pretty well."
