Metroplex transforms into a Cybertronic bucket-wheel excavator. Acessories: "Sparkdrinker", gold Giant Planet Cyber Planet Key.This is what happens when the design team spends too much time on designing a 'cool' robot mode, apparently. Metroplex continued to aid the Autobots, from engaging Ransack in the final black hole battle to being a crew member on the new space bridge project. Undeterred, Metroplex accompanied the Autobots into the depths of his world, eventually facing off with Menasor in a brief clash that ended with reconciliation between the two. Galvatron would encounter him again, quickly defeating the lumbering giant. Metroplex would soon encounter Megatron and beat him into submission, destroying Nemesis Breaker in the process, and eventually triggering his upgrade into Galvatron. However, they changed their minds upon learning that a younger bot, Menasor, had agreed to help the Decepticons.


At first Metroplex and Quickmix refused to let them into the cities, as it was one of their sacred laws to never enter a city they had previously built. Optimus Prime and Vector Prime explained that they needed to find the Gigantion Cyber Planet Key in order to save their own homeworld, and that they believe the clues may be hidden in the older cities on Gigantion. As this was clearly not the case, he and his subordinate Quickmix agreed to hear out the newcomers. When the Autobots first appeared on Gigantion, Metroplex was at first wary of them, believing the group to be from the mysterious Planet X.
