Bloodlines (comics)
（重定向自Bloodpack）
"Bloodlines" was a 1993 comic book story arc published by DC Comics. It was an intracompany crossover that ran through DC's superhero annuals and concluded with a two-issue 'Bloodbath' miniseries written by Dan Raspler. The antagonists were a race of monstrous xenomorph-like aliens who killed humans for their spinal fluid. A small fraction of the parasite's victims survived and become super-heroes via their ordeal. This plot device introduced a wave of "New Blood" super-heroes into the DC Universe. Seven DC Comics series were spun out of the event: Blood Pack, Razorsharp and the Psyba-Rats, Hitman, Anima, Loose Cannon, Argus and Gunfire.
