Teen Titans VOL 04: the Future Is Now

"The Titan's weekends are usually a chance to get away from it all, but this time they're really hones...to the 31st century. There, they must help the Legion of Superheroes stop a threat known as the Fatal Five Hundred. Their return drops them off a mere ten years into the future, but it's not a place they want to stay. Most of the team are horrified at what they grow up to become and what these adult Titans do to accomplish their goals. The final story brings them back home to welcome their newest member, Speedy, who arrives just in time to oppose Dr. Light. His memory restored, Dr. Light comes looking for retribution for the humiliating defeats the Titans have handed him over the years. The dark times of the future appear to be starting right about now..." -- Back cover
