Uriel

Uriel is an angel of god and is Castiel's partner. Unlike Castiel, he has no patience and is willing to sacrifice anything to stop Lilith and the up-and-power Lucifer. He is first sent on a mission to try to stop an old witch from summoning Samhain. He tells the brothers to leave the city, for he is going to destroy it, hoping to wipe out the witch. Sam and Dean refuse, fearing for the citizens. Uriel, however, is willing to kill them in order to stop the witch. Dean tells him to go ahead and do it, but, he must be important if "The Man Upstairs" is willing to bring him back. Uriel hesitates.

Later, he lectures Sam about using his powers. Sam talks back and tells him that his powers saved him and without them he would be dead. Uriel, again, threatens him and tells him the only reason why he is alive is because he's useful, but the moment that ceases to exist, he will be turned to dust.

Uriel makes his return with Castiel when they are sent to capture Anna. The two brother refuses and a battle between them is invoked. Both Sam and Dean are easily defeated but are rescued by Anna, who activates part of her "powers". Then, the boys lead Anna to Bobby's panic room, where anything Supernatural cannot step foot it.Now, waiting out, Uriel and Castiel eventually find Anna. Unknowingly, however, they step into a trap and Anna regains her grace, vanquishing Alastair.

Powers
Uriel demonstrates some unique powers that most Supernatural creatures do not have. He has the ability of Super Strength as he's very easily able to take down Dean. Then, when battling Alastair's subordinates, he is shown to have to the ability of Force Exorcism and is able to rid demons.
