This may have been mentioned previously, but someone suggested that Coulson might be an under-cover Skrull. This would make sence, making a character that no one is familar with in the comics, so the writers have the ability to use him however they want.

I do realise that Lokli summons the Skrulls to take over the world. Meaning Loki would of had to be planning this pre-Iron Man 2, but they may be a way around it.
