Tiefling
Half-Demon/Daemon/Devil race in the D&D games, first introduced with 2nd edition's Planescape. Initially they had hints of demonic nature (teeth, little horns, a tail maybe), now they look demons. Essentially, to add up to all the shit 4e did with races (added Eladrin, fixed Dragonborn, got rid of Gnomes), they fucked up Tieflings. 4e is all about making unnecessary changes shitting up your games...
