A colossus (plural colossi), also known as a crystal giant, is a type of mountain giant. Their flesh is stony and giant crystals stud their shoulders, back, and skull. They can be found in Outland and Azeroth.
Colossi could also be found in Netherstorm and other locations of the shattered world of Outland. The Illidari tried to negotiate an alliance with those in Shadowmoon Valley, led by Behemothon, to no success.
Others could be found in Northrend. One was in the Nexus, and others were in the Halls of Stone. Those in the Halls of Stone were made when the iron dwarves turned their weapons on Ulduar, tunneling through its walls and carving out monstrous crystal giants from the very heart of the mountains surrounding the city. Many friendly colossi could be found helping the earthen of Bouldercrag's Refuge and adventurers.
- They can be mined upon death.
- Behemothon might be Goliathon's successor after he was killed in an earlier quest chain.
- When normal mountain giants are corrupted by the Emerald Nightmare, they resemble colossi.
- As colossi are implied to have some sort of connection to the titans in Wrath of the Lich King, this could imply that the colossi of Outland may be further evidence of previous titan involvement on that shattered world.
