Steeljaw

Steeljaws are a non-sapient race of techno-organic wolves from an unknown planet, possibly Cybertron.

Anatomy
Steeljaws resemble techno-organic wolves.

Powers and abilities
Certain Steeljaws possess transformation abilities akin to Cybertronian.

Behavior
Steeljaws are used by Lockdown to hunt down intruders and prey that venture into his ship.

Background
Centuries ago, Lockdown was tasked by the mysterious Creators of the Cybertronians to capture all their rogue "knights." At some point, he a commandeered and converted a spaceship that had once belonged to the knights themselves into a mobile prison for containing and transporting his various captives.

Over the course of his journey, Lockdown assembled a pack of Steeljaws to help guard his captives. One such Steeljaw was among the minions that Lockdown ordered to stand down when Sojex, one of the mercenary's prisoners, escaped and took command of the ship.

By 2013, Lockdown succeeded in capturing all of the knights save for Autobot leader Optimus Prime. Detecting the energy signature of a collapsing space bridge, he travelled to Earth to acquire this last prize.

Arriving in early 2016, Lockdown landed somewhere in the Arctic and joined forces with the CIA black-ops taskforce Cemetery Wind. The Steeljaws would remain aboard the knight ship while Lockdown assisted Cemetery Wind in hunting Cybertronians on Earth.

Present Day
In 2018, multiple Steeljaws were present on the roof of the knight ship when Cemetery Wind's leader Harold Attinger requested an audience with Lockdown.

When the Autobots infiltrated Lockdown's ship to rescue Optimus and Tessa Yeager, Crosshairs sabotaged the ship's workings and forced it to fire mooring cables into nearby skyscrapers, causing a distraction and buying time. Alerted to stowaways, Lockdown ordered the Steeljaws to find and kill them before the ship departed.

As Cade Yeager, Tessa, and Shane Dyson fled the ship using the anchor, the Steeljaws caught up to the Humans. Using a sword-gun he retrieved from an armory within the ship, Cade opened fire at the Steeljaws while buying Shane and Tessa time to cross. He managed to kill one of them while causing another to fall to its death by shooting at the cables. Undeterred from the loss in numbers, some of the Steeljaws attempted to chew through the wires.

Just when they succeeded, Bumblebee came to the humans' defense and killed two more Steeljaws by impaling one with the death-lock pincer of his plasma cannon and dismembering another. When Bumblebee jumped after a loose cable to rescue the humans, the last Steeljaw chased after the Autobot as he swung. Considering it is never heard from again, the Steeljaw presumably fell to its death.
