Nightmare Colossus

Nightmare Colossi are powerful Nightmares that appear on the Derelict Leviathan.

Gameplay
Nightmare Colossi can spawn in the Royal Pools, where they will be accompanied by two other lesser Nightmares, either Major Incendiors, Major Phalanxes, Major Psions or Elite Legionaries. They will stay more or less at their spawn point, bombarding passing players with their heavy weapons, disorienting them with their Cluster Missiles, and smashing them with their Quakes, which can knock Guardians into walls. While players don't gain much from defeating them, removing them from the map can make other, more useful or rewarding World Events appear in their place.
