Krugg
From Warhammer 40k - Lexicanum
Krugg, known as Krugg the Tyrant, was an Ork Warboss. Initially the ruling Ork of a large part of the world of Eyrok, Krugg was killed by his former Boy Grukk. During their fight for supremacy, Grukk used Krugg's own chain klaw to rip the Warboss' face off, earning the name Grukk 'Face-rippa'.[1]
