Cruellock
- Cruellock is a Decepticon-allied Terrorcon from the Energon portion of the Unicron Trilogy.

Strong and deadly in tooth and claw, gifted with terrifying speed as well as the ability to handle raw energon, Cruellock is a formidable fighter, destined to be feared by Transformer and human citizen of Tokyo alike. Singularly or in vast squadrons of identical units, this robotic raptorbot is a vital tool of war to his Decepticon masters, a mindless menace to his Autobot foes. Strangely and tragically, this seemingly mindless drone is, at its spark, a thinking creature of considerable intelligence... but the only effect this seems to have is to make him more deadly in combat.
Fiction
Energon cartoon

The Cruellock drones were grown in steel eggs by Alpha Q, formulated from a type of "Dinobot" long thought extinct. Once they were finished, the Cruellocks were first sent against both Autobot and Decepticon alike on a frigid, ice-covered world to harvest the energon. Despite some initial shock, however, both groups defeated and escaped the horde. The Return of Demolishor
Later, several Cruellocks were released on Ironhide in a test of strength engineered by Alpha Q and Scorponok, so that the young Autobot could prove his worth to them. The Cruellocks showed themselves capable of transformation for the first time during this battle, crossing their tail blades with Ironhide's Energon Saber. Ironhide eventually defeated them when one ripped the energon star from his arm, and Ironhide blasted the energon, causing a massive explosion. A Tale of Two Heros
Scorponok brought a pair of Cruellocks with him inside Unicron during the attack on Megatron's forces. Open Fire!
Cruellocks fell into disuse for a time, but Scorponok brought them back during an open assault on Cybertron after Unicron's destruction. The Cruellock drones destroyed a space port, trapping the Jones family on Cybertron under siege. Ambition They were attacked by the Autobots when Prime's crew attempted to retake Cybertron from the Decepticons. Wishes

While blasting their way through the train stations on the way to Central City, Kicker and the Autobots shot up a number of Cruellock and Insecticon drones. Several Cruellocks also lay siege to the medical facility where Bulkhead and other Autobots were recuperating. Decepticon Army
Energon comic
Cruellock was a member of the Terrorcons, a group of former Decepticons led by Scorponok, who, unhappy with the Autobot-Decepticon alliance, struck a deal with Alpha Quintesson to raid Earth for its Energon reserves in order to restore Unicron. When Scorponok blasted Starscream into an ore-grinder in Cyber City’s eastern energon processing plant, Cruellock threw the switch that activated the machinery, crushing Starscream’s body, much to Cruellock’s delight. This Evil Reborn
Granted an energon-powered Hyper Mode by Unicron, Cruellock and the other Terrorcons went to Earth to extract the energon buried in the wilds of Australia. However, thanks to the intervention of the Omnicons and Kicker Jones, their Energon siphons were destroyed, and Alpha Quintesson forcibly pulled the Terrorcons from Earth. What Lies Beneath
Though Cruellock himself is not seen again, countless drones based on his beast mode design were sent to raze Tokyo as part of a worldwide assault on Earth coordinated by Alpha Quintesson. The Autobot forces deployed to counter the invasions were not enough to stop the hordes, and only the intervention of the newly revived and hyper-powered Megatron was able to turn the tide and send the Terrorcons back to Unicron.

Toys
Energon
- Cruellock (Basic, 2004)
- Japanese ID number: SD-12
- Accessories: Sword, pistol
- Cruellock transforms into a dinosaur-monster somewhat reminiscent of the American movie version of Godzilla (Now known as simply "Zilla"). He came with a small clear-green hand-pistol and a large clear-green sword, both of which store in his tail in dino mode. These pieces can combine into an "Energy Blade" Ultimate Energon Weapon that can be used by other Transformers toys. He also came with a clear-green Decepticon-style energon chip that can be attached to most Energon toys.
- This mold was also used to make Doom-Lock and Age of Extinction Grimlock. In Japan, his sword was used to make the "Energy Blade Phantom Night Edition" promotional exclusive energon weapon, plus a pack-in energon weapon with Galvatron General.
Super Link

- Cruellock (2007)
- A 32-point "common" character in the 3D Battle-Card Game's "Energon Wars" expansion, Cruellock "transforms" into a red kaiju-type beast. He uses the same parts layout as Predacon Megatron and Grimlock. His color scheme more closely resembles Doom-Lock, although this could be handwaved away as the card actually representing "Dinobot Magma Type".
