The All Mighty Oracle is a truth telling oracle who made his only brief appearance in The Golden Fleas 2.
When the gods kept striking Kazius with lightning, he ran to the Oracle to ask him a simple question, to which he responds "It is decidedly so". Kazius asks the Oracle if Amius and Yumius will return with the Golden Fleas before the gods struck him with lightning again. Silence breaks until the gods do strike Kazius with lightning again, and the Oracle answers "No!".
- The Oracle bears a perfect resemblance to the Koi Fish, only with a different voice.
