The Covenant lives in video game infamy as one of the most iconic groups of baddies ever. These creepy-crawly aliens with their futuristic armor and slimy skin look as scary as they do cool — making them a fitting group of enemies to take on Master Chief.

In the Halo series, the Covenant refers to an alliance of multiple alien species, all united under a belief that the aliens will one day be able to activate a super technology and ascend to join the gods. Although these aliens share a common goal, the organization seems to have some sort of unwritten requirement that none of them could be good-looking.
