Munin, the second raven of Odin
Hugin and Munin are the two ravens of Odin. In Norse mythology, Hugin and Munin travel the world bearing news and information they have collected to Odin. Hugin is "thought" and Munin is "memory". They are sent out at dawn to gather information. They perch on the god's shoulders and whisper the news into his ears.
It is from these ravens that the notation "raven-god" for Odin is derived.

Munin in his human form (Munin Ravenwing)
Obviously in our spheres Munin is able to change into the shape of a human being.
In addition he seems to have considerable magical powers.
