Bungie introduced Marathon, the forerunner of all the Halo business. It featured not one but three AIs, all with starkly different personalities, and one of them psychotic. Unfortunately, such was the site of the art of actual game AI that the random human NPCs displayed an almost unerring tendency to get in the way of every shot or sight line. So they became known as "Bobs."
