Arch Criminal, Science Villain, and High School Teacher (in the "Biz" they call this a "A Triple Threat"). A well known fixture of the "Bad Boy" set since the 1950's, he was known as "Jonny Giant-Head" in the popular press, but his students just call him "Mr. Gin" (pronounced Gin). Gianni suffered a rather public humiliation at the hands of a neanderthal super hero, who ripped off his arms and beat him nearly to death. He is skittish at the prospect of actual physical combat and has numerous advanced devices designed to keep him from harm. Some of them even do what they are supposed to (Some of them).
