Orkamungus

Orkamungus was the Ork Warboss of the first Dawn of War (and ONLY the first one) who clashed his forces with those of the Blood Ravens under Gabriel Angelos. Unlike his eventual replacements, he not only wasn't that impressive, but he also lacked any awesome or memorable lines, and wasn't very kunnin'. Predictably, this led to him getting krumped.

Well, eventually, that is. At first, he was just fine fighting the average humies and looting their tanks. In fact, it wasn't until about halfway through the story before he even makes an appearance, and in that appearance, he's forced to play distraction to the oncoming Blood Ravens by the kowtowing of SINDRIIIIIIIII (to Lord Bale's displeasure) since the two gave Orkamungus the idea of going to Tartarus in the first place so he could go fight. Course, Orks don't like taking orders, and the big boss wanted to go krump both the Imperials and Chaos forces as soon as possible. This meant throwing everything they got, meaning a predictable mob of Boyz, some Deff Dreds, Wartrakks, Looted Tanks, and a Squiggoth or two. However, being nothing more than second-string mooks, this was all for naught and Orkamungus got flattened by the Space Marines, who then proceeded to reclaim some "gifts" of their own.

In Conclusion

A completely forgettable Ork Boss with a stupid name.
