Ibid

Ibid, the Owl of Wisdom is the beloved pet of Athena and eternal companion. It has a very special power that causes anyone who holds him to gain infinite wisdom. He is featured prominently in the episode "Hercules and the Owl of Athena", where Ares wished to shave him in revenge for Athena shving his Dogs of War. Athena lends him to Hercules to guard him from Ares. When Hercules comes to know of Ibid's special power to increase one's wisdom, he uses him to cheat in a test. Ares' sons, Fear and Terror, also uses him to finish a game (having never gone past "Start" before). Ibid is generally seen with his mistress Athena when she appears. Like his mistress, he is blue.
