Cherubim

Cupids
Cupids, or Cherubs, as they are sometimes called, are the lowest specie of angel, but possess an amazing power. One is featured in "My Bloody Valentine". Within the episode, Castiel thought that a cupid was the one making people kill each other for love. He appears as a naked man in the series. Their "handshake" is hugging someone very tightly and apparently nobody likes it, as evidenced by Castiel.

They all follow Heaven's orders, particularly serving Michael. In their occupation, they are responsible for manipulating affection in certain, special bloodlines likewise with Dean and Sam.

There are dozens of them stationed on Earth, according to Castiel.
