Arctus

Arctus is an Autobot from the movie continuity family.

Why do you hesitate to extinguish our species?

Arctus is a non-combatant Autobot engineer in the secure facility used to launch the AllSpark into space.

Arctus concerns himself with the tangible reality around him and has little grasp of weighty philosophical issues; something either is or is not, action should be taken, or not taken. Hand-wringing will not change an unpleasant necessity.

Fiction

Titan movie comics

Arctus could not understand why Optimus Prime hesitated to give the command to launch the AllSpark into space. Optimus proceeded to monologue at him.

When a Decepticon combat drone attacked the facility, Arctus stayed in launch control and did not join the fighting. Optimus ordered him to launch the AllSpark if he wasn't back in ten cycles.

As Optimus defeated the drone, Arctus launched the AllSpark into space before Prime realized it may have been a mistake. Prelude: Optimus Prime
