Nemesis Breaker
- Nemesis Breaker is a Decepticon in the Cybertron portion of the Unicron Trilogy continuity family.

Nemesis Breaker says, "Rarrr!" That's because he's a soulless, sparkless creature of rage, seemingly nothing more than a physical manifestation of Megatron's power and hatred, as well as Leobreaker's jealousy over Optimus Prime's usage of Wing Saber as his new power mushroom.
- Japanese name: Dark Ligerjack
- Polish name: Nemesis Wielki (Nemesis the Great)
Fiction
Cybertron cartoon
When Megatron returned after his defeat in the fire dimension, he was little more than a ghost surrounded by black fog, part of Unicron's shadow spark. As he recreated himself Megatron also used his newfound shadow power to ensnare Leobreaker. His shadow force bled off from the Autobot and took form, creating Nemesis Breaker, an evil clone forged from Leobreaker's primal rage and base animal instincts. Little more than a pet for Megatron, Nemesis Breaker still provided the Decepticons much needed ferocity, as well as a power-up for his master to form Dark Claw Mode, the mirror equal of Optimus Prime and Leobreaker's Savage Claw Mode. Although Megatron relished in the newfound power Nemesis Breaker gave him, he still kept his eye on the prize. Megatron and Nemesis Breaker tricked Prime into believing they desired a final one-on-one battle. Instead, the Decepticons pulled out at the last moment and sped off towards the now-towering Omega Lock. Darkness
As the Decepticons approached the Omega Lock, Nemesis Breaker eagerly ran alongside his master. The Autobots intercepted them, but combining into Dark Claw Mode for his master was almost as fulfilling. Happy Grrrr! Memory And continuing to serve as his master's arm was even more enjoyable! But then Ransack and Crumplezone called Nemesis Breaker's master, telling him the starship Atlantis may have information about the last Cyber Planet Key. Nemesis Breaker and his master separated and warped to Earth's moon to locate the starship, only to see it warping out as soon as they arrived. Sad Grrrr...Escape
When Megatron got his ass beat down bad by Metroplex, Nemesis Breaker disappeared, presumably into a plot hole, though it's curious that whatever happened to him didn't have any effect on Crumplezone, who had recently been brought back from death's door as Dark Crumplezone by the use of the same mystery doodah that Megatron made Nemesis Breaker out of.

Later, when Megatron tapped into the Gigantion Cyber Planet Key and upgraded into the über-powerful Galvatron shortly afterwards, it seems he didn't care enough to recreate Nemesis Breaker.
Toys
Cybertron
- Nemesis Breaker (Voyager-class, 2005/2006)
- Japanese ID number: EX-01
- Accessories: Tail/whip, Jungle Planet-type Cyber Key
- A redeco of Leobreaker in the typical-to-evil-clones scheme of black and dark gray with turquoise trim, Nemesis Breaker transforms into a robotic lion with electronic sounds. Plugging a Cyber Planet Key into each of his forelegs/forearms flips down a pair of claws. He can also form something resembling a clawed arm that can be attached to the Cybertron Leader-Class Optimus Prime and Megatron molds. He comes with a silver-bordered Jungle Planet style Cyber Key; the Hasbro version has the Key code "v6f5".
- The Takara version of the toy was released first, as a Toys 'R' Us exclusive. (It was originally solicited as a normal retail release with the ID number "GD-14", but supposedly, low sales of Galaxy Force forced several larger show-toys into being exclusives.) The Hasbro version was released at normal retail, and had numerous small paint application changes, most notably the Decepticon-sigil "tattoo" being on his right shoulder, rather than left.
- This mold was retooled into Universe Leo Prime and BotCon 2009 Razorclaw.
Notes
- The television CGI model of Nemesis Breaker used during the combiner sequence animation, as well as the representation of the combined arm mode is based upon a modified version of one of the original prototypes of Leobreaker, who had a much more complex and believable 'arm-mode'.
- Despite his packaging marking him as being from the Jungle Planet, Nemesis Breaker never even so much as set foot on that world. Also, the bio states that he was created by Galvatron, whom Megatron did not (re-)assume until AFTER Nemesis Breaker is wiped out in a highly pathetic way.
- The only times he's actually in Robot Mode that don't involve Dark Claw transformation are in the episodes Escape and Warp.
