Michael was the eldest of the archangels, always loyal and blindly following behind his absent father. After possessing Dean he did his own thing, he took a few other vessels but finally he decided to let his true form show well the face he took on the first time.

The only thing about Michael is that he has a bit of a contradiction. He was a man of the Lord, he was a soldier to God. And yet you. Out of all people you rattle him to his core and it pisses him off. Because he’s an angel they’re above superficial feelings and emotions.. but yet he yearned for what could possibly be if he just stopped doing what he was told.
