Either make him all powerful and all knowing as you intended at the start or have him actually face danger, interesting plots and put him in a position to work for it. What you've done is remove all sense of conflict and tensíon right at the beginning of your story and then keep throwing various problems at him and force him to be pathetic in order to not show himself and fake tensíon, and it's just not fun to read. You can't have your cake and eat it too.
