Deffboss

Deffboss, a play on Death Star crossed with Boss and transliterated into Orkish, is an ork that's been fightin and winnin since the War in Heaven against the Shiny Boyz, and what with the fact that Orkz grow larger the more they fight, Deffboss is now the size of a moon. An entire Orkish ecosystem exists on his body, millions of orkz manning Deffboss's enormous weapons and fighting on his behalf wherever he brings his sixty million year old WAAAGH!!!.
