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. Having no mind of its own, it therefore 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. 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 equipment controlling it and Silas himself. 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 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

- Nemesis Prime (Voyager, 2012)
- Part of the eighth wave of TakaraTomy Prime toys, Nemesis Prime is a metallic-black, dark-gray, and translucent-red redeco of AM-01 Optimus Prime, and transforms into a truck. He uses foil stickers for his headlights and insignias, and the sticker sheet also includes an optional set of teal sticker details to apply. Unfortunately, the required placement of an insignia sticker for his right robot-mode shoulder conflicts with the optional placement of a sticker that forms the left half of the teal deco for the truck-mode roof.
- He comes with Giza, a robotic saw shark who transforms into a sword that's based on one of Optimus Prime's arm blades. It pegs into his hand via 5mm post, covering the hand to give the appearance of integrated weaponry. Prime features additional peg-holes on either of his shoulders, half-translucent forearms, legs/truck rear sides, outer forearms/truck hood sides, and back/truck-mode "sleeper cabin" side panels. In vehicle mode, his truck rear gains an additional trio of peg-holes (including the fifth wheel hitch), and the roof of the vehicle mode cab can also fold back to reveal two additional peg-holes. Giza himself has numerous 5mm pegs on his person, as well as a single peg-hole on top of his blade.
- The Hasbro version of this mold, but with the forearms from this tooling, was retooled to make Prime: Beast Hunters Ultra Magnus.
