Oh, oh! Can I be an Orc? Can I Can I ? Can I?
I was thinking his personality would be a mixture of "Oh, hey a fight!" and " The hell did my ale go?! You took it did you?!" But generally 'neutral'. He'll follow his own whims at times, but unlike a truly neutral character--he isn't an individualist first and foremost. He understands, to some degree, that the actions of one can condemn or redeem many. Hey may not be the brightest character; the fact that he comes from a union of Orc and human (albeit not willfully) and that he grew up in a very savage, unforgiving environment and still wants to do better than what his people tend towards; the violence and of human and elven kind whom they feel the need to cull and rebuke. In this sense, he can be very intelligent as he has the foresight to see that fighting humans and elves is often a futile effort.
On the other hand, as they say, he IS an Orc--at least partially. So fighting is like breathing to him. He can be entirely violent, even downright savage. He is a lumbering behemoth of a half-orc. He looks quite like what one would imagine an Orc would be like. He's a womanizer, a brute but overall, he means well. He just...doesn't always understand Elven or human traditions!
