The Ogre Vag is a pretty smart person, as far as Ogres go. This made his childhood a little bit harsh because the dumber Ogres always mocked him. This caused him to leave at a young age. In the wild he managed to survive on his own, becoming quiet resilient and strong. After many years he met Serkis, whom he quiet liked. From this moment the partnered up, Serkis was the brain, he the brawn.
