Merrick

Merrick is an Imperial Guard Sergeant of the 85th Vendoland in stationed in Subsector Aurelia during the timeline of Dawn of War 2.

Why Merrick is badass

Merrick is voiced by Scott McNeil, which automatically makes him awesome, but no, it does not stop there, he's a prime example of what balls-of-steel guardsmen are all about. One thing that makes Merrick a total badass is that he is virtually unkillable, he survived through the first Tyranid invasion including the supposed suicide mission to the poison the Hive Mind, the Black Legion's incursion in the sector, another decade of non-stop combat with Chaos, Tyranid, Ork, and Eldar remnants in the sector, and upto the events of Retribution.

He gets killed in the first Tyranid mission by the Hive Tyrant, but we all know that the Tyranid ending can't possibly be canon, so it's no loss. He is also a snarky bugger, muttering under his breath about how much he'd like to shoot his superiors.

Level him up to the point where he has no setup time for heavy weapons, and watch him tear apart whole units. If you give him the Autocannon with the random artillery barrage ability, Watch him solo missions

Machine Spirits don't seem to like his jury rigged repairs however.
