デカマシンが出撃した隙を突き、エージェント・アブレラが巨大マシン・アブトレーラーをデカベースに突入させた。わらわらと侵入するドロイドの大軍勢。地球署最大のピンチにボスは? スワンは? そして、デカレンジャーはどう立ち向かう?
Agent Abuerra has taken over DekaBase while the rangers take one of his allies. With this, Kruger takes on the reborn Hell Brothers and he does well...until he is threatened by Abuerra that one more step and Swan had it. Kruger saves Swan and puts her in a escape pod. Meanville, the Dekarangers defeat one of the allies of Abuerra with the DekaBike Robo. Back to Kruger: Kruger continues to fight the Hell Brothers but at the end....he is destroyed and dies. Not to mention that the ranger's zords are destroyed and find themselves hopeless as they gloom over Kruger's death. But soon Sen-Chan has a thought as he leads the rest of the gang to the Space Zords as they take on the DekaBase Robo, but nonetheless, their powers are deduced by Abuerra himself as they are painfully fought by the Hell brothers.
