This was the intro piece to the Batman Brave and the Bold Episode with Dr. Fate and Batman battling Wotan.
For the next battle I couldn't find the video but here is the link: http://www.youtube.com/watch?v=yT1hZOD5MvI This is from the Young Justice episode where Aqualad dons the Helmet of Fate and becomes Dr. Fate to battle Wotan. Great episode!
