Millennium Edition: Showcase 4 #[nn]

In "Mystery of the Human Thunderbolt!", Barry Allen’s life changes in an instant when a lab accident with lightning and chemicals grants him super-speed, inspired by the 1940s comic book Flash. Now forced to embrace his new identity, he must confront the bizarre and seemingly unstoppable Turtle Man—known as "The Slowest Man Alive"—in a battle that tests speed against patience in ways no one could have predicted.

In "The Man Who Broke the Time Barrier!", the Flash captures the fugitive Mazdan, a criminal who was meant for a distant future but instead wound up stranded in the 20th century due to a failed time transfer. With time itself unraveling around him, the Flash must stop Mazdan from rewriting history before the timeline collapses.
