However, this Engineer was outfitted with a biomechanical pressure suit that probably also increased its strength and durability by working as a biotechnological power suit. They also seem to be extremely strong and resilient given to the fact that the Last Engineer killed Peter Weyland's escorts by sending them flying across the room from simple punches and was impervious to gunshot damage at close range. Their musculature appears very similar to that of humans, with visible musculature matching up closely with the general build of humans.

The name 'Engineer' was given by Elizabeth Shaw and Charlie Holloway due to the lifeform being responsible for 'engineering' the human race. The Engineers have a multitude of different names deciphered hieroglyphic tablets found in Tanaka 5 referred to them as 'Ossians', whereas the decoded beacon of the Derelict Ship from LV-426 made reference to a species known as 'Mala'kak'. 4 Relation to the Xenomorphs and other races.
