Captain Janeway's animal guide
As part of the Native American vision quest, an animal guide offers spiritual guidance. No one can choose their own animal, the animal chooses them. Each one is unique, but does not represent the person. It would offend a guide if its identity was revealed to others. Chakotay prefered not to say the name of his guide as it may be offended; all he did reveal was that it wasn't the bear, and that was only because he was correcting Janeway's earlier guess. Under the guidance of Chakotay, Katherine Janeway discovered her Animal guide was a tokay gecko. B'Elanna Torres was noted for being the only person Chakotay knew who actually tried to kill her animal guide on her vision quest. (VOY: "The Cloud")
