Continues from Marvel Preview #24.With issue #25, Marvel's black-and-white showcase magazine MARVEL PREVIEW was re-titled BIZARRE ADVENTURES.  Content remained more or less the same, with themes changing every issue.  The series continued to feature stories starring new and established Marvel Universe characters (some left over from other canceled series), new stand-alone stories, and adaptions of prose fiction.  The final issue, #34, was published in a color comic book format, rather than as a black-and-white magazine.

Summary:

Earth has been liberated from the Aliens (xenomorphs), though their contamination remains. Despite living in relative safety above a skyliner high above the surface, genetically engineered trophy-wife Caryn Delacroix is haunted by nightmares of being hunted through the streets, of death, and of having her perfect, privileged life stripped away and replaced by another. However, Caryn's nightmares soon become reality as Maria DeMedici and Tommy Shirow detect a cloaked ship Earth-bound, and Caryn comes face-to-face with the monster from her dreams, uttering the name, "Ash Parnell."
