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 article, 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.

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.

On its first excursion, Nemesis Prime attempted to ram Agent Fowler off a bridge, but retreated when Autobots arrived on the scene. However Arcee followed it into an abandoned petrol station but was able to blindside her and escape. It later attempted to frame Optimus and the Autobots by transforming and attacking Alden Military Base. It, again, retreated when the real Autobots showed up.
Nemesis Prime soon confronted the Autobots in battle when they were close to MECH's base, taking them out one-by-one. Eventually, Optimus confronted it in combat after the other Autobots had been defeated. After a lengthy battle, it seemed that Nemesis Prime had the advantage, but Silas briefly left the robot's control chair to battle Agent Fowler hand-to-hand. Nemesis was left immobile and directionless in the interim, allowing Optimus to gain the upper hand. As Silas desperately jumped back into the controls, Optimus smashed the copy through the roof of MECH's base, sending it crashing down on the equipment controlling it and crushing Silas. The injured MECH leader was pulled to safety by his men. Nemesis Prime
Nemesis Prime's body was placed in storage by the military. General Bryce mistook Nemesis Prime for Optimus Prime and took the Autobot leader as dead. He soon changed his mind after Fowler's testament and a conversation with Optimus. Grill
