Vampirella versus Red Sonja (Vampirella versus Red Sonja #1)

It's a monumental clash of titans that had to happen, from master storyteller Dan Abnett! Both Vampirella and Red Sonja were recruited by the Project, a cosmic collection of superheroes sworn to protect all known universes. But Vampirella is now considered a murderous criminal - and she's capable of defeating any hero. Unfortunately for her, Red Sonja is no hero... It's a universe-spanning, action-packed battle royal from start to finish, by Dan Abnett (Dejah Thoris) and Alessandro Ranaldi (Jennifer Blood)!
