Ephraim

Ephraim was an angel hailing from a special class, rit zien. He fell to the earth from heaven due to the spell cast by Metatron. Upon arrival, he took the vessel of a man who had recently become very religious. While on earth, he continued his work as a medical angel--healing the sick and, more importantly, bringing swift and virtually painless death to the gravely injured or emotionally despondent by smiting them. His first victim was his vessel's wife. He came across Castiel, who Ephraim wanted to help by ending his pain once and for all. With the help of Dean, Castiel killed him with an Angel Blade when he tried.

Early Life
Ephraim met Castiel several years ago. Ephraim envied Castiel's fame and power, he admitted he knew Castiel failed more often than he succeeded but he always went big.

Season 9
He makes his first appearance in Heaven Can't Wait. He took possession of a man who had become deeply religious, so much so that he drove his wife away. Blinded by religious fervor and a desire to serve God, the man let Ephraim into his body. Ephraim began a killing spree, using his abilities of pain-detection to track down the gravely injured or emotionally despondent and using his healing abilities to heal them or his special smiting abilities to give them a quick and virtually painless death, ending their misery. He was killed by Castiel.

 * Pain Detection - As a rit zien, Ephraim could home in on pain and suffering.
 * Healing - As one of the healing class of angels, Ephraim possessed the power to heal both angels and humans.
