It's often said that Venger is the most powerful sorcerer in the show (besides Dungeon Master, apparently), and it only afraid of one thing; Taimat, the five-headed dragon. In fact, in an unproduced final episode, the kids decide to defeat Venger once and for all by using Tiamat. I think to examine Venger's strengths, we need to take a look at Tiamat's. Each of the five heads breaths a different elemental effect - the main head is the typical fire, but the other heads appear to breath ice, poisonous gas, shadow (?), and electricity. He appears to be invulnerable to any of Venger's blasts, although he was hurt when Venger enhanced his attack with the kids' magical weapons. Too bad it only happened once. Besides that, Venger ends up being chased away by Tiamat when they face off. If that's the only thing he's scared of, that's still damned impressive.
