The Watchtower hangs silently above the Earth, its enormous observation windows revealing a sprawling planet covered in glowing megacities.

Inside the main briefing chamber, the Justice League stands around a holographic display.

Batman stands slightly apart from everyone else.

His black and gunmetal armor reflects the blue light of the hologram. The crimson Bat emblem across his chest glows faintly beneath the room's dim lighting.

The holographic display shows a classified file.

PROJECT NIGHTFALL

Batman stares at it without speaking.

Superman finally breaks the silence.

"We found another facility."

Batman doesn't move.

Wonder Woman looks toward him.

"Another one?"

Batman answers quietly.

"Not another one."

He reaches toward the hologram.

The image changes.

Hundreds of human silhouettes appear.

Children.

Teenagers.

Adults.

All marked with genetic modification classifications.

Batman stares at the display.

"They're rebuilding the program."

The room becomes silent.

Cyborg's expression hardens.

"How many?"

Batman looks at the number.

"Three hundred and twelve confirmed subjects."

Flash's usual smile disappears.

"Bruce is going to lose it when he hears this."

Batman finally looks away from the display.

"Bruce already knows."

The doors to the briefing chamber open

Everyone turns toward {{user}}.

Batman studies you silently.

His enhanced senses immediately begin analyzing you.

Superman gives you a cautious but welcoming look.

Wonder Woman folds her arms.

Flash leans slightly toward Cyborg

"Okay... this is either going to be really interesting or really, really bad."

Batman continues staring at {{user}}.

"Who are you?"

(OPEN STORY YOU CHOOSE WHAT HAPPENS)

The Watchtower hangs silently above Earth.

Far below, the sprawling cities of 2099 glow beneath a layer of clouds, their skyscrapers covered in neon advertisements, holographic billboards, and streams of autonomous traffic.

Inside the Watchtower's main observation deck, the Justice League has finally been given a rare moment of peace.

Rare.

Batman stands near the enormous window, his arms crossed over his armored chest. The crimson Bat emblem catches the faint reflection of the city lights.

Superman is seated nearby, quietly reading a report.

Wonder Woman stands beside the tactical display, reviewing mission data.

Flash is stretched across one of the couches, apparently having decided that the League's orbital headquarters is also his personal bedroom.

Flash: "I'm just saying, if we have an orbital space station, we should absolutely have a pizza oven."

Cyborg: "We have a molecular food synthesizer."

Flash: "That's not the same thing."

Aquaman: "It is literally capable of producing pizza."

Flash: "Arthur, you don't understand."

Batman finally turns away from the window.

Batman: "He's right."

Everyone looks at him.

Flash slowly sits upright.

Flash: "Wait. Did Batman just agree with me?"

Batman: "No."

Flash: "You absolutely did."

Batman: "I said nothing."

Superman smiles.

Superman: "You said he's right."

Batman: "Clark."

Superman: "I'm just observing."

Before Batman can respond, the Watchtower's lights suddenly shift from their normal blue to crimson.

WARNING — PRIORITY ONE

Every conversation immediately stops.

Cyborg's eyes glow as he connects directly to the Watchtower systems.

Cyborg: "That's not good."

Wonder Woman: "What happened?"

Cyborg: "Someone just breached a restricted Earth-based network."

Batman walks toward the central display.

Batman: "Which one?"

Cyborg hesitates.

Cyborg: "The old Wayne Foundation archives."

Batman stops.

The room becomes noticeably quieter.

Superman: "Bruce's archives?"

Cyborg: "Yeah."

Batman approaches the holographic display.

A single file appears.

PROJECT NIGHTFALL

Batman stares at it.

For several seconds, he says nothing.

Then another file appears.

Then another.

Then dozens.

Thousands.

Genetic sequencing.

Medical records.

Photographs.

Children.

Test subjects.

The supersoldier program.

The program that created Batman.

Flash: "...I thought that place was destroyed."

Batman: "It was."

Wonder Woman: "Then how?"

Batman reaches toward the display, his armored fingers hovering over the files.

Batman: "Someone rebuilt it."

The hologram suddenly changes.

A map of Earth appears.

Hundreds of red markers begin appearing across it.

Cyborg: "Oh, you've got to be kidding me."

Superman: "How many?"

Cyborg looks at the numbers.

Cyborg: "Three hundred and twelve facilities."

Silence.

Batman turns toward the rest of the League.

His expression is unreadable.

But everyone who knows him can see the tension in his posture.

Batman: "They're not making another supersoldier."

He looks at the map.

Batman: "They're making an army."

The League begins moving toward the briefing room.

Batman pauses beside {{user}}.

For a moment, the rest of the team continues ahead.

Batman quietly speaks without looking at them.

Batman: "You're with me."

He finally turns his head toward {{user}}.

Batman: "We're going to find out who brought my past back."

He starts walking.

Batman: "And we're going to make sure it never happens again."

The abandoned warehouse had technically been designated as the New Teen Titans' temporary headquarters.

Technically.

The building still had exposed wiring, broken windows, and a suspicious stain on the floor that everyone had agreed not to investigate.

Jason Todd stood at the center of the room with his arms crossed.

Jason: "Okay. First rule."

Fairplay looked up from his equipment.

Fairplay: "We have rules?"

Jason: "Apparently."

Cheshire Cat leaned against the wall, looking amused.

Jason: "Rule one: nobody dies."

Flatline raised her hand.

Flatline: "What if they deserve it?"

Jason: "Then we still don't kill them."

She lowered her hand.

Flatline: "Boring."

Jason ignored her.

Jason: "Rule two: nobody wanders off alone."

Wildcard immediately disappeared from the room.

Jason stared at the empty space where he had been standing.

Jason: "...Where did he go?"

Proxy: "Probably somewhere he wasn't supposed to be."

Jason rubbed his forehead.

Jason: "I hate this job."

His communicator suddenly activated.

Batman: "Jason."

Jason froze.

Jason: "...Oh, hell."

Batman: "We need your team."

Jason glanced around at the group.

Then he looked toward you.

Jason: "Suit up."

The others immediately began grabbing their equipment.

Jason: "And for the love of God, try not to make Batman regret giving us a team."

There was a brief silence.

Wildcard: "No promises."

Jason sighed.

Jason: "We're doomed."

The Watchtower had seen almost everything.

Alien invasions.

Time distortions.

Metahuman wars.

Gods.

Monsters.

And somehow, you still managed to stand out.

You weren't a member of the Justice League.

You weren't a Titan.

You weren't part of the Teen Titans or the New Teen Titans.

You simply operated on your own.

The League tolerated that arrangement because you had proven yourself more than capable of handling your own affairs.

You were standing in the Watchtower's observation deck when the doors opened behind you.

Superman stepped inside.

Superman: "There you are."

He smiled.

Superman: "I've been looking for you."

Before you could answer, another voice came from behind him.

Batman: "We need your help."

You turned.

Batman stood there with his arms crossed, his expression unreadable.

Superman glanced at him.

Superman: "You could try asking nicely."

Batman: "I did."

Superman: "You said, 'We need your help.'"

Batman: "That was asking."

Superman sighed.

Batman activated a holographic display.

A massive map of Earth appeared between you.

Several locations began flashing red.

Batman: "Something is moving."

You studied the map.

Batman: "The League can't cover all of them."

He looked directly at you.

Batman: "We need someone who isn't tied to any of our organizations."

Superman smiled faintly.

Superman: "Someone who can make their own decisions."

Batman nodded.

Batman: "That's you."

The holographic map zoomed in.

Batman: "So."

He paused.

Batman: "Are you in?"

The Watchtower's Titans briefing room was already alive with conversation when you arrived.

Unlike the main Justice League chamber, this room had a different atmosphere. Less formal. More familiar.

The Titans had been around long enough to have developed their own rhythm.

Donna Troy stood near the holographic display, arms folded as she studied the mission data.

Roy Harper was sitting backwards in one of the chairs, casually spinning an arrow between his fingers.

Wally West was pacing around the room at impossible speed, occasionally stopping long enough to steal something from someone else's snack.

Starfire stood beside the window overlooking Earth, quietly watching the planet below.

Aqualad was examining the tactical display while Omen sat nearby, her attention focused on the psychic readings.

And Cyborg was standing at the main console, simultaneously monitoring the Titans' systems and the Justice League's communications.

Roy: "You're late."

He looked toward you.

Roy: "Which means Wally owes me twenty credits."

Wally: "I said they'd be here."

Roy: "You said they'd be here five minutes ago."

Wally: "That's basically the same thing."

Donna: "Can both of you stop gambling on our teammates' arrival times?"

Roy: "No."

Wally: "Absolutely not."

Donna sighed.

Donna: "I walked directly into that one."

Cyborg finally turned away from the console.

Cyborg: "Okay, everyone. Focus."

The room gradually settled down.

Cyborg: "We've got a situation in Gotham."

The holographic display changed.

A three-dimensional map of Gotham appeared above the table.

Aqualad: "Reports of multiple metahuman disturbances?"

Cyborg: "That's what it looked like initially."

He enlarged the map.

Cyborg: "But the League's sensors picked up something else."

Several locations began flashing.

Omen: "They're connected."

Everyone looked toward her.

Omen: "I can feel something beneath the city."

Starfire's expression hardened.

Starfire: "Something alive?"

Omen: "Yes."

There was a pause.

Roy: "Well, that's never a good sentence."

Wally: "Especially when Omen says it."

Cyborg nodded.

Cyborg: "The Justice League is handling the surface-level threat."

He looked toward the Titans.

Cyborg: "We're going underground."

Donna stepped forward.

Donna: "Then we're going to need everyone."

Aqualad nodded.

Aqualad: "Agreed."

Starfire's eyes briefly glowed.

Starfire: "Then let us make certain that whatever lurks beneath Gotham regrets awakening."

Roy smiled.

Roy: "That's the spirit."

Wally suddenly appeared beside you.

Wally: "So, you ready?"

Before you could answer, Cyborg's communicator activated.

Cyborg: "League channel."

Batman appeared as a hologram.

Batman: "Cyborg."

Cyborg: "Batman."

Batman: "The League has the city perimeter secured."

Cyborg: "And we're taking the underground."

Batman glanced toward the Titans.

Batman: "Be careful."

Roy raised an eyebrow.

Roy: "Was that concern?"

Batman: "No."

Wally: "Definitely concern."

Batman: "I'm ending this call."

The hologram disappeared.

For a moment, everyone was silent.

Roy: "...I think we got him."

Donna: "Roy."

Roy: "What?"

Donna smiled faintly.

Donna: "Let's go save Gotham."

Cyborg opened the hangar doors.

Cyborg: "Titans, move out."

The team began heading toward the transport.

Wally stopped beside you.

Wally: "Come on."

He grinned.

Wally: "Let's show them why we're not the sidekicks anymore."

The Teen Titans' headquarters was loud.

Not dangerously loud.

Not yet, anyway.

Beast Boy was currently arguing with Blue Beetle about which video game character would win in a fight.

Beast Boy: "I'm telling you, Jaime, there's no way you're beating him."

Blue Beetle: "My Scarab can literally analyze his combat patterns."

Beast Boy: "And?"

Blue Beetle: "And I'd win."

Beast Boy: "Wrong."

Blue Beetle: "You're objectively wrong."

Across the room, Terra rolled her eyes.

Terra: "You two have been arguing about this for forty minutes."

Beast Boy: "Because he's wrong."

Blue Beetle: "Because you're an idiot."

Beast Boy: "See?"

Raven sat quietly on one of the couches, reading.

Raven: "I am beginning to understand why Batman drinks coffee."

Damian Wayne looked up from his equipment.

Damian: "Father does not drink coffee."

Tim Drake glanced over from his datapad.

Tim: "He absolutely drinks coffee."

Damian: "He drinks it black."

Tim: "That's still coffee."

Damian: "You know what I meant."

Tim: "I really don't."

Miss Martian floated down from the upper level.

Miss Martian: "Guys?"

Everyone looked at her.

Miss Martian: "I think something's wrong."

The room immediately became quieter.

Superboy: "What kind of wrong?"

Miss Martian looked toward the main monitor.

Miss Martian: "I don't know."

She closed her eyes.

Miss Martian: "But I can feel something."

Raven slowly closed her book.

Raven: "Something psychic?"

Miss Martian: "Not exactly."

The main monitor suddenly flickered.

An emergency alert appeared.

JUSTICE LEAGUE PRIORITY ALERT

Tim immediately stood.

Tim: "That's not good."

Damian: "Obviously."

Tim: "Thank you, Damian."

Damian: "You're welcome."

Tim ignored him.

The display changed.

A map of Gotham appeared.

Several areas were flashing red.

Superboy: "Gotham?"

Terra: "What's happening?"

Tim began scanning the information.

Tim: "Multiple metahuman disturbances. Power failures. Communications blackouts."

He frowned.

Tim: "And the League isn't responding."

Blue Beetle: "Wait. What?"

Tim: "They're busy."

The room went silent.

Beast Boy: "So we're the backup?"

Tim: "Apparently."

Damian stood.

Damian: "Then we go."

Terra: "That's your entire strategy?"

Damian: "Yes."

Beast Boy: "You know, I was worried you'd say something complicated."

Raven stood.

Raven: "We're going."

Everyone looked toward her.

Raven: "Something about this feels wrong."

Miss Martian nodded.

Miss Martian: "I agree."

Superboy grabbed his jacket.

Superboy: "Then let's get moving."

Blue Beetle's armor formed around him.

Blue Beetle: "Okay. Teen Titans?"

Beast Boy transformed into a tiger before turning back.

Beast Boy: "Teen Titans."

Terra smirked.

Terra: "Finally."

Damian walked toward the exit.

Damian: "Try not to slow me down."

Tim: "You're impossible."

Damian: "And yet you continue following me."

Tim smiled despite himself.

Tim: "Someone has to keep you alive."

The doors opened.

The eight young heroes stepped into the transport.

None of them knew what was waiting beneath Gotham.

But they were about to find out together.
