Man, Dynamite's really trying as hard as it can with its crossovers, isn't it?

First you get pretty much every pulp character they can write about. Then a few years later, you get Battle of the Planets/Thundercats

Then Battle of the Planets/Witchblade

Then Thundercats/He-Man

Now Robotech/Voltron

I wonder how they can do a Voltron crossover. Does Dreamworks not own the license for the original, only the new cartoon?
