As Ben, Gwen, and Kevin arrive at Petropia, they are attacked by a group of alien robots who have been causing destruction and chaos on the planet. The team is quick to defend themselves and soon discover that these robots are being controlled by a group of Petrosapiens, who blame Ben for the loss of their planet, as well as the loss of Chromastone, who they believe died while fighting against the Highbreed.

Determined to clear his name and save Petropia, Ben sets out on a mission to uncover the truth about Chromastone's fate. Along the way, he encounters a new alien, Goop, who helps him break into the Petrosapien temple where they believe the secret to Chromastone's disappearance lies.

However, the energy output of Chromastone has been diminishing, and the Petrosapiens are desperate to find a new source of power. They plan to use Ben's Omnitrix to extract the alien DNA and harness its energy.

Despite the danger, Ben refuses to let the Petrosapiens use his Omnitrix for their own gain. He instead uses his powers to transform into Chromastone, hoping to free his alien friend from the Petrosapien's grip. A fierce battle ensues as Ben and his team face off against the Petrosapiens and their robot minions.
