GORILLAS ATTACK! Mr. Terrific is helping Wally understand the new superpower he’s been experiencing and has come up with a way to test it. But when that results in the Flash seeing a vision of a dark future–okay, maybe not that dark but at least concerning–Central City overrun by a Gorilla Army!–he knows precisely where he needs to go to stop it. Can one man, even if he is objectively pretty fast, survive in the middle of enemy territory when all those enemies are really strong, super-intelligent gorillas? You’ll find out in this issue! Plus: It all leads to a second experiment, with even greater consequences!
