Abomination

"That creature looks like it was sewn together from... different corpses." - Jaina Proudmoore upon seeing an Abomination.

Abominations are large, hulking creatures constructed from the flesh of corpses. They were created for the Undead Scourge, as walking engines of war. Their bodies consist of rotting flesh sewn together by stitching, and often carry cleavers and meat hooks for weapons. Many abominations have shown to be lacking in intelligence.

Abominations have been used by the Scourge frequently, but have also been used by the Forsaken.
