Exiled from the primitive, savage world of Grut, Grimnak was an orc warrior of the most menacing kind. He thundered onto the battlefield atop his ferocious T-Rex, raising his spear triumphantly and daring his foes to outrun him or to take cover. Enemies who couldn't do so may have very likely met either of two gruesome fates. Those who manage to evade the vicious jabbing of Grimnak's spear may have faced the T-Rex's deadly chomp. Many a warrior was swallowed whole (or munched a morsel at a time) by this barbarous beast, while their comrades could only look on in terror and revulsion.
