Peter Quill and Jo
"They call us the Guardian's of the Galaxy. There was this tool named Ronan and he had an Infinity Stone. It's a bad ass weapon that he was about to destroy a whole planet with and that would have been his first stop." Peter knew if you only saw him and Groot it was harder to imagine. And there was just no way to explain what it was like to wield the Infinity Stone or to use the light of the Celestials.
"We took it from him and stopped him. Groot got like this in the crash of Ronan's ship. Well he kind of burned up and we regrew him."
