I've said it before, I can say it again.
Superman vs. big-ass, Transformers
Done and done.
What's the hold-up, already?!
Of late, I've thought that a Toyman story which used licensed properties would be a rather good idea. Superman vs. Transformers, G.I. Joe, Micronauts, AT-AT imperial walkers, Gundams of all stripes, and beyond. It makes more sense than a Toyman who uses giant Nutcracker Suite dolls. I mean, maybe I'm way off, but toy nerds aren't that into the ballet.
I don't know: has this been done before?
(Well, I am aware of the He-Man crossover.)
Anyway, side-point, Toyman would be a decently effective villain for a film. He's no Brainiac, but then, who is?
