Let me start off by saying I love ducks. The riddler is cool, but there is whole universe of cool characters in Disney's treasure trove. 

Duck Tales #2 just came out the other day (need to get that soon) and Darkwing Duck #13 came out the week before (check out my review!). A Cross-over between these two series has been whispered about for several years now, ever sense Darkwing duck first graced tv screens everywhere  with former duckburg (and Ducktales) resident Launchpad McQuack. However, although there were some characters who appeared in Darkwing's home of St. Canard in his Television series who also appeared on Duck Tales ( Gizmo Duck, for example), there has never been an official crossover between Duck Tales and Darkwing Duck. Until now, that is.
 
Although we are only on Duck Tales #2, publishers always are working months in advance. According to Darkwing Duck Artist James Silvani (on his blog) in Duck Tales #5 we will see " the beginning of the great Duck Tales/Darkwing Duck crossover!" Here are the non-colored, inked covers for that issue:
