Nemesis Prime (Prime)
| The name or term "Nemesis Prime" refers to more than one character or idea. For a list of other meanings, see Nemesis Prime (disambiguation). |
- Nemesis Prime is a MECH-created Transformer from the Aligned continuity family.

The human-manufactured robot known as Nemesis Prime is a mindless drone created by MECH, controlled remotely by a human operator. In order to cause psychological, as well as literal, damage, the machine was built in the exact likeness of Optimus Prime, the leader of the Autobots. Nemesis is capable of operating as both a semi-rig truck and a humanoid combat robot with the same strength, agility, and firepower as the original one, except with MECH leader Silas in control. It has none of Prime's moral strengths and also lacks any form of pain receptors, making it an utterly merciless killer robot.

Nemesis Prime was the culmination of MECH's Project Chimera, an almost exact copy of Optimus Prime controlled by Silas from MECH's base of operations. Nemesis Prime In preparation for Nemesis Prime's creation, MECH took a complete scan of Optimus Prime's body Convoy, abducted and analysed Breakdown's body components Operation: Breakdown and took Starscream's T-cog and installed it into Nemesis Prime's body. Operation Bumblebee, Part 2
On its first excursion, Nemesis Prime attempted to ram Agent Fowler off a bridge, but retreated when Autobots arrived on the scene. Arcee followed it into an abandoned petrol station when Nemesis blindsided her and escaped. It later attempted to frame Optimus and the Autobots by transforming and attacking Alden Military Base. It made another retreat when the real Autobots showed up.

Nemesis Prime confronted the Autobots when they were closing in on MECH's base, taking them out one-by-one. Optimus confronted it in combat after the other Autobots had been defeated. After a lengthy battle, it seemed that Nemesis Prime had the advantage since it was impervious to pain. Before Nemesis could finish off his foe, Silas had to vacate the robot's control chair to battle Agent Fowler hand-to-hand. Nemesis was left immobile in the interim, allowing Optimus to gain the upper hand. Silas desperately jumped back into the chair, but was too late. Optimus smashed Nemesis through the roof of MECH's base, crushing both the the equipment controlling it and Silas himself. The highly injured MECH leader was pulled to safety by his men off-screen.

Nemesis Prime's body was placed in storage by the military. General Bryce mistook Nemesis Prime for Optimus Prime and believed the Autobot leader was dead. He abruptly changed his mind during Fowler's testimony when he had an unscheduled face-to-face conversation with Optimus. Grill
