Anatomy
Freezers share a similar biology to other Cybertronians, except their robot modes are insect-like with four optics and four arms, they scale around the same size as humans, and transform into weapon artillery.

Freezers share many of the same abilities as other Cybertronians.

Despite their frame, Freezers having enough brute strength to smash through doors.

Freezers can move stealthily with their ability to cling to walls.

Weaknesses
Freezers share many of the same weaknesses as other Cybertronians.

Culture and society
Freezers form the bulk of the Terrorcon army, functioning as both foot soldiers and weapons for their superiors. Primarily loyal to Terrorcon leader Scourge, they are often sent out to sniff out prey for their master.

Being affiliated with the Terrorcon faction, Freezers are technically servants of Unicron.

History
In 1994, Scourge deployed two Freezers to retrieve the Transwarp Key and kill any Humans aware of its existence. Pursuing Elena Wallace and Noah Diaz through the museum, one of the Freezers was about to get to Elena when Noah momentarily stopped it by hitting its head with a relic. Managing to run out the exit, the humans were caught in a heated battle between the Autobots and Terrorcons was taking place. Both Freezers followed the humans outside, where they attacked and fought against Mirage until the battle was over.

When the Terrorcons followed the Autobots and their allies to Peru, one of Scourge's Freezers was dispatched with the same mission of killing the humans and retrieving the Key. Crossing the rooftops, the Freezer avoided detection mostly due to Mirage being distracted by "groupies". Going underground into the buried city, it snuck into the chamber with the empty coffin which had once contained half of the Key. When Noah noticed it sneaking up behind Elena, the pair ran for their lives. The lone Freezer gave relentless chase, nearly killing them several times. It was eventually killed by Noah using a Cybertronian gauntlet given to him by Mirage.

When the Terrocons obtained and assembled both halves of the Transwarp Key, hundreds of Freezers came through a gateway the relic generated. Engaging in battle with the combined Autobot and Maximal forces, the Freezers proved that despite being individually weak, they had sheer numbers on their side. Concurrent to this, Scourge dispatched his remaining Freezer to hunt Elena through the access tunnel, cornering her over a pool of lava before she impaled it in the head and sent it falling into the magma.

Despite the deaths of fellow Terrorcons Battletrap and Nightbird, the Freezer army would later be reinforced by several Scorponoks sent by Unicron. When Autobot leader Optimus Prime destroyed the Transwarp Key, many Freezers were incinerated by the resulting explosion. Those that survived explosion were sucked into the collapsing Transwarp portal.
