Monolith is a minor villain from Champions Online who appears exclusively in Nemesis missions, where he works for the titular "Nemesis" - despite being a minor villain he is clearly a very brutal character and his description alone shows that he is likely a feared individual within the extended Champions universe.

In-Universe Description

Some say Monolith is in it for the money, others swear he does it for the fame or infamy...the truth is he enjoys wiping the smile off a hero's face when they see him snap the necks of helpless victims. He's a bully, he knows it and likes everyone else to know it, too.
