Der finale Roboter-Kampf wird ausgetragen. Umataro muss gegen seinen Rivalen Dr. Lolo antreten. Wer wird als Sieger hervorgehen?
With Six back and ready, he's not the only one joining the fight. Dr. Lolo and her robot Mars are joining the battle too. She calms that her robot will fight everyone. Meanwhile, Six starts to think about the people around it and comes to a decision. Soon, the Deadly Taurus, Drum Shoulder, Hell Scissors, Six, and Mars begin their battle. However, as the battle goes on Mars beats off the other robots with relative ease. He cuts through them like butter until it's down to just him and Six. As they both prepare for the battle that's coming, it becomes clear that Six is not just a robot. For he asks why Mars fights and wants to talk with him.
決勝戦はバトルロイヤル形式で行う。ディフェンディングチャンピオン、マルスのオーナーであるDr.ロロからの思わぬ提案にロボレス会場は衝撃に包まれた。同じ条件で参戦したすべてのライバルを打倒するのがマルスだと、宣言するDr.ロロ。盛り上がる会場をよそに、蘭はＡ106が充電している様を見つめる。Ａ106は今、何を“考えている”のか…。「プロトコル・スタンバイ。返信を求む」。そしていよいよ決勝戦が始まる。
Poco prima dell'inizio della finale, la dottoressa Lolo fa un annuncio imprevisto e sconvolgente: alla Battle Royale parteciperà anche il suo campione uscente Mars.
