Tainted orc

From WoWWiki

This article or section contains lore taken from the Warcraft RPG books.

Tainted orcs gain a monstrous form. Tainted orcs look like Orcs of massive size, 8 feet tall. They have green skin mottled with gray and their dark hair hangs with thick tangles. Their eyes shine with crazed, savage light. Orcs once cultivated a shamanistic society upon the dying world of Draenor. Then the dark magics of the Burning Legion corrupted them. Lured to the world of Azeroth through a dimensional gateway, they were manipulated into waging war against human nations. Recently, most orcs threw off the shackles of demonic influence and now strive to recover their lost heritage. Some orcs remain under the thrall of the Burning Legion, however, to the point where they are twisted into mockeries of their former selves. Orcs appear to other races as a barbaric and brutal people, but they are proud and noble in their way. Those subject to demonic taint give vent to their brutish ways, however. A tainted orc can channel his warrior fury to become truly fearsome in combat. A tainted orcs body has swelled in size due to the Burning Legion’s corruption, gaining a monsterous form. Anger rules the tainted orc’s heart, diplomacy and intimidation are less effective on the orc. ^{MoM 127,128}

Tainted orcs show some signs of corruption (large size, mottled skin) but lack the red skin of fel and chaos orcs.
