Kru-Gark is the shaman for his tribe of Ogres. He's a formidable NPC but not much of a fighter; if attacked by your players he is likely to be swiftly overwhelmed. However, he should be able to command the loyalty of many more Ogres. In my game, he guarded the entrance to the lair of the Ogre Half Red-Dragon and Ogre Dire Were-Bat, which he regarded as powerful servitors of the spirit world.
With a few rounds to prepare, Kru-Gark could get a few black bears and some bull's strength going, and be a real handful. Remember that when casting bull's strength on himself, he can share spells with his animal companion.
