Yanme'e Engineer

The Yanme'e Engineer is a type of Covenant unit which is depicted inside the Art of Halo book.

Background
They appear only in Halo 3 ODST. Their combination of insect organics and cybernetics makes them a unique-looking creature in the Covenant bestiary. And since they can actually fly, with the aid of gas-filled bladders on their backs, they behave differently, too. This species can be biomechanically and cybernetically altered to suit specific tasks, other than engineering and maintenance. Engineer Drones help repair Covenant spacecraft and aircraft that have faced minor to moderate damages.
