It was always a thrill for comics fans when the producers of Smallville would introduce other comic heroes into the TV show mythos. Over the years, we saw versions of Impulse, Green Arrow, Black Canary, Aquaman, Cyborg, Doctor Fate, Sandman, Hawkman, Zatanna, Star-Spangled Kid, Stargirl and Martian Manhunter. Heck, even the Wonder Twins from the old Super Friends animated series put in an appearance.
But the one character that never appeared on the Smallville TV series, the one that fans were dying to see, was Bruce Wayne as Batman. It was rumored over the years that he would appear at one time or another but it never happened, most likely because the character was off-limits because of the successful Batman movie franchise.
