Hero Factory? I've heard of that!
Of course, that shouldn't be such a surprise since I'm a fan of Bionicle, and Hero Factory is intended to be it's replacement, at least as far as releasing new Lego sets.
Maybe after I'm finished with my LBT/Bionicle crossover stories (yes, I'm planning on writing many more) I think I might try a LBT/Hero Factory crossover as well. But don't expect it to happen for a while. Like I said, I've still got much more left to write for my LBT/Bionicle fanfics and that is going to take quite a while. Besides, the Hero Factory storyline has just started. I certainly wouldn't mind waiting a few years until I decide to start writing such a fanfic, since it'll give me a better idea of how such an idea could work out.
