Zagan is a particularly intelligent demon, able to anticipate all things and put that foreknowledge to action. Whatever he does or says, he is unrivalled in speed and matchlessly cunning.
Added on September 14, 2012 as a reward in Battle Royale III:
Zagan is a Great King and President of Hell, commanding over thirty-three legions of demons. He makes men witty; he can also turn wine into water, water into wine, and blood into wine (according to Pseudomonarchia Daemonum: blood into oil, oil into blood, and a fool into a wise man). Other of his powers is that of turning metals into coin that are made with that metal. Zagan is depicted as a griffin-winged bull that turns into a man after a while.
