Ep 12. Predatory

In Transformers Prime season 1 episode 12, titled "Predatory", the Autobots are facing a new threat in the form of a rampaging Insecticon that is causing chaos around the city. Meanwhile, Arcee is dealing with her own past as she tries to track down a former Decepticon partner, Airachnid, who betrayed and left her to die.

As the Autobots work to contain the Insecticon, Arcee's search for Airachnid takes her to a remote location where she comes face-to-face with her long-time enemy. But things quickly take a dangerous turn as Airachnid reveals her true intentions and the two engage in a intense battle.

With the help of the rest of the Autobots, Arcee is able to overcome Airachnid and bring her back to base for questioning. But as they interrogate her, they realize that she isn't the only threat they're facing - the Insecticon's actions were not just random destruction, but part of a larger Decepticon plan.

As the Autobots delve deeper into the Decepticon's scheme, they discover that Megatron has been working on a powerful new weapon that could mean the end of the Autobots and the triumph of the Decepticons. Now, the Autobots must race against time to uncover the full extent of the Decepticon plot and stop Megatron before it's too late.

Throughout the episode, there are also several emotional moments as the Autobots reflect on their past and the sacrifices they've made in the ongoing war. It's a tense and action-packed episode that sets up the rest of the season for even more epic battles and high-stakes drama.
