外星機獸的最高統(tǒng)帥——天隆，派出擅長使用機械怪獸的部下——魯奔達，魯奔達在他的戰(zhàn)艦中有個電腦獸，尋找機器人。這時翔峰做噩夢，

　　魯奔達放出大量電波蟋蟀吸取森林樹木的能量，對地球展開進一步的侵略計劃。翔峰、古力和好友一同去新開的馬戲團觀看表演，在表演演出時，一臺菱形的機械怪獸突然來襲，機械怪獸使用強勁的電力攻擊與浮游防護盾，讓烈空焰天驅(qū)雷星魂戰(zhàn)士找不到攻擊的突破口。

　　后來古力來到，天驅(qū)雷找到機械獸弱點，由嘯天寒先攻冷冰，后來天驅(qū)雷烈空焰為嘯天寒掩護，于是烈空劍烈空焰用烈空斬，最終戰(zhàn)勝敵人。魯奔達打算調(diào)查到指揮官。

　　Tianlong， the supreme commander of the alien machine beast， sent a subordinate who was good at using mechanical monsters， lubenda。 Lubenda had a computer beast in his warship， looking for robots。 At this time， Xiangfeng had a nightmare，Lubenda sends out a large number of radio waves。 Crickets absorb the energy of forest trees and carry out further aggressive plans against the earth。 Xiangfeng， gulee and their friends went to the newly opened circus to watch the performance。 During the performance， a diamond shaped mechanical monster suddenly attacked。 The mechanical monster used strong electric attack and floating shield， so that the fierce sky flame sky drives thunder star soul soldiers can't find a breakthrough。Later， when Guli came， tianqulei found the weakness of the mechanical beast and attacked the cold ice first。 Later， tianqulei's strong air flame covered xiaotianhan， so the strong air sword and strong air flame cut with strong air and finally defeated the enemy。 Rubenda is going to investigate the commander.
