Double Jeopardy

Double Jeopardy is a episode in Transformers: Universe (Reboot).

Plot
Agent Fowler drives out of a military base, listening to a few tunes, when a red car begins to tailgate him too close for comfort. He realizes that it's more than a case of road rage when the car rams him. Fowler contacts the Autobot base for help. The red car continues to attack, and as Fowler comes upon a bridge, he pushes his car through the divider, where it hangs precariously. The Autobots receive his message and bridge in, causing the red car to flee and Arcee to give chase. Bumblebee catches Fowler's car as it falls, but the bumper detaches, and Bulkhead catches it before it hits the ground. Arcee comes upon she thinks Knock Out, but the car transforms into a red copy of Bumblebee. Arcee is shocked until she is knocked out when a red copy runs her over.

The next thing she knows, she's back at base, being checked up on. Ratchet doubts Arcee's assertion that she mistake the double for Bumblebee. Optimus Prime arrives at base and offers proof that he's been at an underground energon site. Carlos was confused, but Alexis knows about Bumblebee's "double". The team realizes that MECH has finally succeeded in replicating Cybertronians, inside and out, using human-made parts after studying Transformer anatomy so carefully.

The three kids and the Street Action Team sneak into into the Gen-U-Tech databanks; MECH collected half the spark of Starscream, Breakdown's eye and Thundercracker's T-Cog to create a clone of Bumblebee, Stinger.

This places its lair within driving distance of both incidents, giving a range for them to search. The 'bots fan out, and Bumblebee comes upon a large complex. Optimus and the rest plan to rendezvous at his position. He enters, while Silas watches him. He powers up his Nemesis Prime, and sends it out. Bumblebee is briefly fooled by the fake, until Silas slips and reveals he cannot understand Bumblebee's speech. The scout attacks but is quickly overpowered by his doppelganger.

The rest of the Autobots enter the compound, cautious of any lookalikes. Bulkhead and Arcee are both taken out individually, leaving Optimus for the final showdown with his doppelganger. Galvatron and the real Nemesis Prime watch.

At base, Ratchet attempts to isolate the control frequency of Nemesis Prime to pinpoint the location of its operator. He does, and Fowler insists on bridging in, citing that he is the one best equipped to deal with the "human element".

Nemesis squares off against Optimus, showing equal strength and agility. Fowler bridges in, and makes for the control bunker as the two Primes continue to spar. Nemesis catches Optimus, and shoves its blade into the Autobot leader. Silas gloats, commenting that he cannot feel pain through the robot, unlike his opponent, and revealing his intentions to build an army of these soldiers, when Fowler enters. They spar as well, and Fowler falls to Silas' superior hand-to-hand combat skills, only to reveal that he was just buying time for Optimus to beat the now-directionless copy. The real Prime dominates Nemesis, and their fight knocks Stinger, sending the clone fly in the air.

Stinger sees Galvatron appear over him with the Dark Star Saber. Stinger wakes up in the Revenge where Galvatron brands him a Decepticon symbol. He welcomes him into the Decepticon fold.
