How about it? If GBIII had a chance of getting made, I'd like to see the movie GB's fight the Ghost-Clones from the RGB ep. “Citizen Ghost”. Man, if those were the main villains, the film would kick so much ass!
The plot could revolve around them getting created, somehow, in the movie universe, and they try to bring Gozer back. So, the GB's get back into action….. again! But Gozer tries to doublecross the GC's, so, in the end, the GB's and GC's team up, and destroy Gozer. Then, the GB's turn on the GC's, and Trap them.
I just love evil clones!
