There was a recent episode of "Batman the Brave and the Bold" that featured a cross-over of Batman and Scooby-Doo. This is the latest incarnation of Scooby, "Scooby-Doo Mystery Incorporated".
Of course this easily reminds me of the old Scooby-Doo movies that featured Batman and Robin in ther "Super Friends" years. We have that one on DVD (both movies) and we are looking forward to seeing this new one, "Bat-Mite Presents: Batman's Strangest Cases!".
This got me thinking. If Batman and Scooby-Doo can have a crossover, why not Zatanna and the Hex Girls! The set up should not be too hard really. Both are scheduled to perform at the same town/locale and something weird happens (something weird always happens) and all four would be needed to solve the mystery/case! It's really not all that far-fetched given the logic of both universes. Plus Jennifer Hale does the voice of both Thorn and Zatanna so that is not a stretch, obviously I am not the only one to think so. An on going gag can be that the Hex Girls are bit star struck with Zee and in the end she is the one that asks them to autograph copies of their CDs (That is if Zee is an NPC).
Now the question is, what system to use?
For a one shot or one off adventure like this I would not use Smallville's version of Cortex since I think it works better with a season long plot and Hex Girls games are more "monster of the week".
Mutants and Masterminds 3rd Edition might also be a good choice. Zatanna is already stated out in the DC Adventures book.
I have done Zatanna and Hex Girls for Witch Girls Adventures and that still feels like the best first choice.
Cartoon Action Hour would also be fun, and the new look for the Hex Girls that I was using for CAH:2 fits well with the Bruce Timm design of Zatanna.
So what would the focus of the adventure be? Something bigger than a Chupacabra or ghost. No we would need something worthy of Zatanna. Maybe Modru. I never liked that guy, and even though he is more of a Legion of Superheroes bad guy, he has the magic to go up against Zee. Modru it is.
I think I'll even pull a cliché out of the bag and have Modru turn Zee evil and the Hex Girls (ie the players) have to turn her back to good and then defeat Modru.
And in typical Scooby-Doo/Hex Girls fashion the girls play a song (I am thinking "Magic" by America) at the end, with Zee on stage doing some magic.
Maybe this is the start of a Season 3.
