Teaser: Batman and the Outsiders (Black Lightning, Katana, Metamorpho, Geo-Force and Halo) must thwart Kobra's plan of global domination and his army of cultists.
Main Plot: Two years ago, Barry Allen and Batman worked together to save themselves from villains like Gorilla Grodd, Captain Boomerang, and Mirror Master. Two years later, the Rogues (consisting of Heat Wave, Weather Wizard and Captain Cold), Jay Garrick and Kid Flash are depressed over Barry Allen's apparent death when he was pursuing Professor Zoom.
However, after seeing the mysterious ghost of Barry Allen, Batman and the two Flashes use the help of the Cosmic treadmill to travel to the 25th century, where Professor Zoom has taken over as the conqueror.
- The Ace: The Barry Allen Flash.
- All Up to You: After Barry was lost, Wally stepped up to defend the city full-time.
- And I Must Scream: Professor Zoom captures Barry and places him into a device that will increase his power and empower his regime. The machines force him to run nonstop, and has been in this condition ever since his supposed death quite some time ago.
- Antagonist in Mourning: The Rogues all reminisce fondly about the Flash, and are ecstatic to see him back. (Though all of them deny this)
- Badass Boast: "I'm the Flash. Speed is my game."
- Big Damn Heroes: Jay and Wally free Barry in time to save Batman from Zoom.
- Casting Gag: Zoom is voiced by John Wesley Shipp, who played Barry on the 1990 series.
- Curb-Stomp Battle: Batman is easily outmatched by Reverse Flash making it one of the few times he is beaten.
- Heroic Sacrifice: After they went so fast that they ended up in another dimension, Barry sent Jay and Wally back through the portal and was presumed dead.
- Hoist by His Own Petard: After luring Zoom into his own trap, the Flash stops to trip him causing Zoom to spiral out of control and collided with the glass walls. Combined with super speed, Zoom sped across and receives further damage.
- It's All My Fault: Both Jay and Wally blamed themselves on Barry's presumed death.
- Manly Tears: Weather Wizard express complete joy upon seeing Flash that he nearly cries.
- More Expendable Than You: Jay feels guilty about losing Barry because he didn't do this, saying he's getting on in years while Barry was still a young man at the time of his disappearance. He makes up for it by helping free Barry rather than himself.
- Not Quite Dead: Barry was presumed dead, but he really ended up a prisoner of Reverse Flash.
- Poor Communication Kills: Neither Jay nor Wally ever mentioned seeing visions of Barry to each other.
- Pretender Diss: The Rogues dismiss Jay as "Geezer Flash" and remark it's just not the same as facing Barry. "Baby Flash" showing up is outright called lame.
- Real After All: Jay had been seeing visions of Barry everywhere, but he assumes they were just hallucinations brought on by guilt. Batman seeing the visions is something else, as is Wally admitting he's been seeing them, too.
- The Scapegoat: Wally took Barry's apparent death out on Jay because he blamed himself for what happened.
- Something We Forgot: After thwarting Kobra, Batman asks the Outsiders if they made sure no reinforcements come. Given their sheepish expressions (and the army of reinforcements marching across the bridge), they didn't.
- Talk to the Fist: When Heat Wave begins insisting that the Rogues aren't beaten yet, Batman punches him out mid-sentence.
- True Companions: Batman and the Flash are good friends. After the Flash was gone, Batman decided to protect his fallen friend's city from its criminals.
- Villain Respect: The Rogues expressed fond memories of Flash beating them and their desire to destroy him.Batman: You... miss him.
- What the Hell, Hero?: Batman calls out on Kid Flash that it was neither Jay's and his own fault and to stop clinging onto the past.
