Watchtower II

Superman (DCAU) overlooked the members of the Justice League (DC) from the control deck as they teleported up to the Watchtower.

It had been a month since the Cadmus incident and Lex Luther (DC) being imprisoned. Since Cadmus's disbandment, the Justice League has been making steps towards correcting the flaws they had been overlooking and rebuilding the bonds between the people they swore to protect. Such steps include disabling the Binary Fusion Cannon the League had constructed and deployed during the Dark Heart invasion. Building the Metro Tower on Earth to bring the League closer to the people. And working more closely with the Government, keeping their liaison, King Faraday in the loop of need to know incidents.

Another change was that several members were elevated to the same status as the original seven founders, including Green Arrow, Aquaman, Captain Atom, Red Tornado, Steel, Black Canary, and Zatanna (DC). They also reached out to Shazam (DC) and offered him back into the League, which he accepted with honor on the ground that the League kept to their promise to be better. The Huntress (DC) was also reach out to for her part in the Cadmus incident, but she declined.

"Is that everyone?"

Superman turned and saw his fellow founders approach him.

Batman (DC) of Gotham City.

Wonder Woman (DC) of Themyscira.

The Flash (DC) of Central City.

Green Lantern John Stewart (DC) of the Green Lantern Corp.

Hawk Girl (DC) of Thanagar.

And J'onn J'onzz (DC), the Last Son of Mars.

Superman turned to Diana "All the full time members are here. Except Kara"

"She's overseeing the transfer of Galatea from Star Labs to a more secured facility" said J'onn.

Galatea (DC) was the clone of Supergirl, made by Cadmus to use against the Justice League. During the attack on the Watchtower, Galatea was rendered comatose. Since then she was kept at Star Labs till she was stabilized.

"This must be very personal for the kid" said Flash.

"She volunteered for this" said Green Lantern "I trust her judgement"

"On another subject" said J'onn as he turned to Superman "Doctor Hamilton's trial is to take place one month from now. Are you to testify against him"

"If asked" said Superman. "I-"

Suddenly, alarms started buzzing around the entire Watchtower. Acting quickly, the founders ran/flew to the control deck, where Mister Terrific (DC) was typing rapidly.

"What's happening?" asked Batman.

"The Watchtower's systems are picking up something trying to hack into it's system" said Mister Terrific.

"The cannon's offline" said Green Lantern "What's being hacked?"

"..." Mister Terrific kept typing as he observed the screens until a look of shock hit his face "The teleportation deck!"

Without wasting time, Batman pressed a button for the intercom. "All members of the League, the teleportation deck has been hijacked! Prepare for anything!"

With the experience of professionals, all members quickly stopped relaxing/socializing and surrounded the teleportation deck as the device started bringing in whoever was coming through. As the device finished it's work, many in the room widen their eyes in shock. Standing before them were the Avengers (Marvel Yost Universe)!

"The Avengers?!" barked Green Lantern.

"But why?" asked Hawk Girl.

Indeed, it was the Avengers, Earth's Mightiest Heroes.

Iron Man (Marvel).

Captain America (Marvel).

Thor (Marvel).

Hulk (Marvel).

Yellowjacket (Marvel).

Wasp (Marvel).

Hawkeye (Marvel).

Black Panther (Marvel).

Ms. Marvel (Marvel).

The Vision (Marvel).

Black Widow (Marvel).

War Machine (Marvel).

The Falcon (Marvel).

"Tony, what is the meaning of this?" asked Superman as the Avengers stepped off the deck, not a word said.

Before anyone could act, the teleportation deck activated again. This time several Iron Legion drones appeared. Before Superman could register what was happening, Iron Man pointed his repulsor glove at Superman and fired.

.

Moon.

On the moon's surface, a being wearing a ragged cloak observed the Watchtower, as if aware of what was happening. A second figure approached the first.

"Such trivial use of the Mind Gem" said figure was an android with a screen head, on the screen was an old man.

"Be silence Collector (Marvel)" said the cloak man, holding a blue gem in his hand "The minds of the Avengers are of strong one, particularly the Asgardian and the Kree Meta-Human. Only the power of the Mind Gem could subdue them without fail"

"You use one of six Infinity Gems to pit these heroes against each other" said the Collector through the monitor "Pathetic. The power of the Mind Gem is only temporary until the Avengers are immobilized. And even with the robotic drones backing the Avengers, the League outnumber and overpower them"

"I just need them to be in one area for ten minutes" said the man as he pulled out a device.

"A Mother Box?" questioned the Collector.

"Such an ease to obtain one these days" said the man "With Apokolips at never ending war, the locals care not for who comes and goes"

"So that is your game" said the Collector.

"Game? No" said the man as he started up the Mother Box "Preparation"

.

Metropolis.

Supergirl (DC) flew over the armed vehicle as guards surrounded the vehicle in the middle, two medics pulling out Galatea on a stretcher as they wheeled her inactive body into the building which was made exactly for her, built by Star Labs themselves.

When Supergirl first met her clone, she was disgusted and violated that someone cloned her and used her powers to harm others. But after the Battle on the Watchtower, Kara only felt pity for her for only being made a weapon.

Kara wanted to head up to the Watchtower to be part of the final details for the changes in the League, but she had to oversee this until Galatea was contained and all was clear. While she waited, she pulled out several newspapers she snagged from Clark's apartment. When one's alter-ego was in the news, a lot of interesting things pop up. She skimmed through the Daily Planet since she usually lived those stories, so she read newspapers from other parts of the world. Clark read them to keep on the lookout for other potential heroes. One such paper was the Daily Bugle. This paper usual covered the activities of the Avengers and the Fantastic 4. Though Kara had to admit the constant harassment of one particular hero was a somewhat annoying.

And then there were these other heroes.

'Kim Possible saves Russian ambassador from Professor Dementor over Europe'

'Powerpuff Girls commemorate 10 years of protecting Townsville by body guarding Mayor'

'Danny Phantom defeats wannabe ghost hunters targeting Fenton Family'

'Static of Dakota keeps the rising Bang Baby resurgence to a minimal'

'Ben 10 reported to have saved 3 planets during speculated road trip in space'

Kara smiled as she read these newspaper covers. It comforted her that even with the risk of the Justice League disbanding, that there were still heroes protecting this world.

.

Superman threw a punch at Captain America as the patriot dodged. Superman then fired his heat vision which was bounced off the captain's shield. As the two were in stalemate, the rest of the League were engaging the Avengers. Batman was maneuvering around Iron Man as the Armored Avenger fired blasts at the Dark Knight. Green Arrow and Hawkeye were at the opposite ends of the room firing at each other. While neither were hit, their shots still found targets in either the Iron Legion or League members. Black Canary and Black Widow were engaged in a fierce fisticuffs. Ms Marvel fired energy blasts at Wonder Woman as she kept her opponent at a distance. J'onn J'onzz and Vision were phasing through the entire Watchtower as they fought, their unique powers countering each other. Captain Atom kept firing at Black Panther as the soldier tried to keep the King's Vibranium claws away from his suit. Falcon chased the Flash around as the Scarlet Speedster stayed one step ahead of the flyer. But while Flash dodged every attack, that didn't mean Falcon couldn't hit adjacent League members around the Flash. War Machine fired his barrage of weapons at the Green Lantern, trying to keep him from concentrating on his ring. Thor was attacking Aquaman viciously, Mjolnir bashing against the Trident of Atlantis. Yellowjacket and Wasp kept to attacking various League members using their shrinking tech throughout the duration of the battle before each finding a respective opponent, Yellowjacket was halted by the Atom (DC) as the two shrinking brilliant minds kept their battle on the subatomic level. As for the Wasp, she started an aerial battle with Hawk Girl, blasting the Thanagarian before shrinking to avoid her Nth metal mace. But it was the Hulk that kept the League from overtaking the Avengers. The Gamma Monster had already defeated half the League while destroying various parts of the Watchtower. Luckily the League was able to evacuate the civilian staff on the Javelins before the Hulk destroyed the hangar.

"Steve enough of this!" roared Superman as he made a grab for Captain America. Steve ducked around and bashed his shield against the back of Superman's head.

"The Avengers are all under enchantments!" groaned Wonder Woman as her arm bands shielded her from Ms Marvel's never ending attack.

"That doesn't matter!" shouted Batman as he threw a Batarang at Iron Man "We need to end this before the Hulk destroys the whole Watchtower!"

Steel came past Superman and swatted Captain America with his hammer.

"Superman, stop Hulk!" shout Steel "I'll keep Capt busy"

"Appreciated" said Superman before moving as fast as he could, arriving in the cafeteria and smacking Hulk into the wall before he could stomp on Red Tornado.

"That's enough Hulk!" shouted Superman.

Hulk only roared as he leapt at the Man of Steel.

.

"That should be enough" said the cloaked man. He pointed the Mother Box at the Watchtower.

He pressed the button.

.

Supergirl widen her eyes as she heard a familiar boom with her super hearing. And where said boom was.

"No" she said under her breath. Without another word, she bolted into orbit.

.

Superman locked hands with Hulk, the two brutes pushing against each other's might. Hulk's might was powerful enough that Superman could do nothing as he heard the boom that usually meant something was coming.

Or something was going.

.

The Collector and the cloaked man watched as the Boom Tube sent away the Watchtower, League and Avengers within.

.

Supergirl was too late.

The instant she saw the Watchtower, it vanished.

"NO!" shouted Supergirl as she floated among empty space, the once proud base of the Justice League gone.

.

The Collector activated a noise canceling barrier around his drone as he watched Supergirl fly around.

"Well it appears you missed one" said Collector smugly.

"Did I?" said the Cloak man "No. This isn't an attack. It's preparation"

"Whatever you're plan is for the Earth, I do not care" said the Collector "Now my payment"

"Understood" said the cloak man as he tossed the Mind Gem to the drone "For the brief use of the Mind Gem, I tell you the whereabouts of the Soul Gem. Adam Warlock keeps it on his forehead"

"Then I shall be taking my leave" said the Collector as the drone activated it's rocket feet "For I need to pay a visit to the Guardians of the Galaxy"

The cloaked man waited as he watched the machine fly away. How easy it would be to destroy the machine and retake the Mind Gem. But the stone did not matter. All that mattered was what the actions of today meant for tomorrow.

.

And so there we have it. The stage is set and the world will change.

As you can see, I'm using the DCAU universe and the Yost Universe for the DC and Marvel slots. I tried using an original DC and Marvel for a previous story, but it got complicated.

Now for those you know, this story is based on the Team Teen story. Or is it Teen Team? Hang on let me check... It's Team Teen. Teen Team is the name for the hero team in Invincible.

Now basically the story is Kim Possible, Ben 10, XJ9, Danny Phantom and Jake Long come together and form a hero team. I'm taking that premise and spicing things up by adding representatives from the Marvel and DC worlds each. And one from an anime.

The DC rep is Supergirl.

The Marvel rep is the Spectacular Spider Man.

The Anime rep is Inuyasha.

And yes, that does mean I'm using anime's in this story. And why not, anime is awesome. But I'm keeping the list thin in comparison to cartoon series and there are some quotas that must fit if I use one.

-They must have an English Dub. And a good one. Not a bad one like 4kids One Piece.

-They have to be something you would see on Toonami or so on. That doesn't mean it had to have been on Toonami. Just something you feel you would assume could be on Toonami.

-No slice of life anime.

-No harem anime.

-No hentai/rated 18 anime.

-No horror anime like Attack on Titan or Berserk.

Now as for the time stamps for when the current seven stories occur.

DCAU- After the Cadmus Arc and before the Secret Society Arc.

Marvel- After both Avengers: Earth's Mightiest Heroes and Spectacular Spider-Man.

Kim Possible- After series.

Ben 10 Omniverse- After series.

Danny Phantom- After series.

American Dragon Jake Long- After series.

My Life as a Teenage Robot- After series.

Inuyasha- After first series and before the Final Act.

And here are the final notes I have.

I'm aware Spectacular Spider-Man isn't part of the Yost Universe. But it feels like it could've been so why not. Same can be said for Teen Titans and DCAU but I'm planning on having the Teen Titans appear somehow.

There will be other series besides the main seven I'm starting with. But I'm focusing on the first seven so things feel more settled in.

And the team name isn't going to be Team Teen. That's been done. Twice. Or more. Besides, I believe there's a Team Teen in MLAATR. Or is that Teen Team. I'll check really quick... Now that one is called Teen Team. Man that's a common team name.

Now the story is called All Star Alliance, but that isn't the team name. I'll think of one by the end of chapter 4.

Next time, the world sets as the new actions shape the world.

Worlds Collide.

REVIEW LIKE HELL!
