"I'm kind of hard to kill, anymore." He could be anything, after all. Something with a healing factor -- maybe even an Agent, himself. Never mind the fact that that hadn't stopped Loki from killing Odin. He could at least put himself on their level, if he really wanted to. "But yeah, alright, we test the waters first."

Which would be easy. One word in any ear and he could have whoever throw themselves at the Agents for his assessment.
