The Prometheans in Halo 4. At least the ones we see excluding the Didact are just basic AI engineered for defense of the Forerunner worlds. Their programming can be corrupted. Also the Promethean's mode of directive and the events of Requiem shouldn't be replicated in RvB. It's non-canon. It can be followed to an extent such as origins, but that's it. In the RvB storyline there are countless oppurtunities for what could happen. So Meta wouldn't be working with the Prometheans. He'd have control over them. Or at least, a group of them. It would be a good twist with the fact that Forerunner technology has turned up in a few past episodes and left a small impression.
