Thor
Upon arriving in the deserts of New Mexico, Agent Coulson along with a unit of S.H.I.E.L.D. agents set up a perimeter and a base of operations around the crater site containing Mjolnir. Coulson then proceeds to gather all of the research Jane Foster and her scientific team had that was related. When Thor attempted to reclaim Mjolnir by infiltrating the Shield base and manage to single-handedly take out a dozen of Shield agents with various fighting styles. Coulson observe from a distance but not before asking Clint Barton to prepare to take action if necessary. After Thor failed to remove Mjolnir, Coulson interrogated Thor about his identity and his training believing him to be a warrior of some type despite Thor refusing to answer his questions. Thor's interrogation was interrupted when Erik Selvig appears and informs Coulson that Thor is actually Donald Blake a member of his scientific staff. An agent confirms it by running a background check in the computer database and turns up a falsified document created by Jane of Thor assuming the identity of Dr. Donald Blake. Coulson goes along with the charade but secretly assigned agents to follow them believing they know more than their letting on. When an agent discovers the coordinates of another potential crater site that appears to having an exact signature match to Mjolnir. Agent Coulson and a unit of agents go to investigate and find The Destroyer armor, One agent asked Coulson if the armor belongs to Tony Stark. Coulson replied that Stark doesn't tell him anything at first he assumes it is Stark when he address the armor until it attack them. Coulson manages to survive the attack from The Destroyer and manages to see Thor regain his powers. Coulson confronts Thor and Thor offers his services in protecting Earth under the sole condition that Coluson return all of Jane's research and material back to her.
