My usual character for New Vegas is named Archibald. He is a CH 1, IN 10, mad professor type who is evil as fuck and only cares about himself and his glorious inventions. He maxes out Energy Weapons, Science, Medicine, Repair and Barter and only takes related perks, and likes nothing better than to fry people with lasers or melt them with plasma. He helps people only so that later he can torture them. Best of all, he looks like a bearded old grandpa, with age slider set to max, white hair, pale skin and totally crazy eyes.
