I haven't started reading it yet but I will.
I do vaguely remember a crossover. It might have been Marvel in the 1980s or 1990s. I really just looked it over and didn't buy it but it was Star Trek with the original crew during the time of the movies crossing over with the Star Wars characters probably after the events of Return of the Jedi.
I remember Spock learning to use the Force on a rudimentary level just because he's telepathic which I thought was hilariously unrealistic. "Stretch out with your feelings". "Forget your conscious self and act on instinct". Oh, yeah. Vulcans are famous for being great at stuff like that.
Hmm, can't seem to find anything on the Net about it. Might have been a fan fiction comic.
