In school, fourteen-year-old Presto (real name: Albert) was the kid with the Coke Bottle Glasses... the clumsy one who wasn't especially good at anything so he took up magic. He figured, that was the only way he'd ever be able to do anything that someone else couldn't do. He drove his friends berserk with "Pick A Card" and earned the nickname under which he performs as an amateur magician. And an amateur is putting it mildly; most of his tricks were unqualified disasters.
As a magician, he was a failure. he wasn't dumb; just disorganised.But that was before he received the Magic Hat that he now wears proudly atop his head in his role as The Wizard. And from that hat, he can produce... anything! Any object -- big or small -- can be made to appear merely by Presto reaching into his hat, uttering a few magic words, and pulling out... something! he can produce a live chicken or a steam roller or a map of Downtown Scranton or a Hot Turkey Sandwich with cranberry sauce. He can produce anything but what he wants. You see, he's no better organised now than he was when he was attempting card tricks in the school yard. Sometimes -- incredibly -- he'll actually produce what he wants. Sometimes -- equally incredibly -- he'll produce the wrong object but his friends will figure out how to use it to solve their current dilemma. (When a three-headed fire-breathing rhino is bearing down on you, you'd be amazed how handy that Hot Turkey Sandwich can turn out to be!)
The power of The Wizard is, potentially, the greatest power of them all -- if only he could get everything working properly. Presto tries hard; oh, how he tries! he is constantly trying to save the day and prove to his friends that he isn't an utter incompetent. (Actually though, it's not them he's trying to convince; it's himself.) Sometimes he succeeds.
He isn't brave but he forces himself to be. His role model is Hank and Presto often spouts Woody Allen style, self-depreciating lines about what a nebbish he is and how he'll never be courageous or strong or handsome or competent as he thinks Hank is. Presto's hero-worship, by the way, is one of the things that gives Hank some of his courage. Anyone who's ever had anyone look up to him knows that feeling: You can't let your fan down. Presto's attitude towards the other kids is very simple: He thinks everyone is better than he is at everything -- but he's determined to change that, someday! For Presto, being in this world may be a strange kind of blessing; you get the feeling that, if and when he ever gets out, the real world won't seem like such a formidable opponent to him.
