Trerror is the Proto-Ultimatrix's DNA sample of a Talpaedan from the planet Terraexcava in the Andromeda Galaxy. Trerror's design was created by RaphLXIV.


Trerror is a beige 12-feet-tall alien with an armored, robotic-like body. His head is similar to a Greek Corinthian helmet with two ears on it giving him the appearance of an armadillo, as well as two pointed teeth on the bottom sticking up. Trerror has a light brown tail with beige armor and a silver spike on the tip, and jackhammer parts on his elbows and wrists, creating the impression that he is a digging cyborg. Trerror has blood that is grey and partially translucent. The Proto-Ultimatrix symbol is located on his chest.

Powers and Abilities

Trerror has incredible digging capabilities thanks to his jackhammer arms, and can transform his hands into drills to help himself burrow underground and move through it. Trerror can even dig through solid rock. His drill hands can also be very useful in battle, as seen when Armodrillo fought Slamworm.

Trerror possesses enhanced durability, courtesy of his armor. He is durable enough to withstand attacks from many powerful opponents, as well as being thrown through walls and other solid surfaces.

Trerror can create destructive earthquakes by placing his hands on the ground and pumping the jackhammer pistons on his elbows. He can also do this by slamming his hands onto the ground.

Trerror is able to create fissures in the ground, although he may have to first dig deep underground to do this.

Using his jackhammer arms, Trerror can create shock waves to blast away larger enemies with a single punch and launch objects he is holding.

Trerror can create enough vibrations to collapse buildings into rubble, as exclusively demonstrated by Andreas when he destroyed a Forever Knight castle.


Even though Trerror's armor is highly durable, it is not strong enough to keep Argit's spikes or Zombozo's bowling pins from hurting him.

Certain weapons can cause Trerror's nervous system to go out of control and make him unable to stop vibrating his arms.

Trerror can be suffocated if a large amount of matter covers his whole body and compresses it enough.

Trerror has a weakness against electricity.

Being a Talpaedan, Trerror is vulnerable to his natural predator, Slamworm.
