This story, my third on (My Second got deleted), is a crossover between Teen Titans and Justice League Unlimited. With New Heroes! New Villains! And new Leagues, this will be better than the show.
-----------
San Francisco, UndergroundGears turned, and occasionally made a high-pitched noise, due to the lack of oiling in this underground room. In an alternate future, this would become the lair of Nightwing. This was the secret hideout of Slade, the Deathstroke.
Slade had many hideouts. One in an old factory, and another in an abandoned underground church. But this one was Slade's favorite. Slade even had access to an old run-down subway system, which Slade was about to utilize. The subway tracks ran all the way to the end of the cave, and then into the Pacific Ocean. That is where Slade wants to be.
Slade hated the Teen Titans, and all superheroes, including the Justice League. Slade did own the League one for saving him during the White-Alien Invasion. This is the reason Slade decided to take up Luthor's offer. Luthor proposed a league of villains to wipe out all Super Hero organizations. Slade turned the Key, and sent the train to the Pacific Ocean.
-----------
Pacific OceanSlade's train landed in a Darth Vader shaped bubble, in the Pacific Ocean. Luthor had underwater tubes built so Slade could access the bubble. In the bubble, he bumped elbows with many villains, including Brother Blood and Joker. Slade made his way into the Auditorium and then sat down. Luthor stood behind the podium in his Kryptonite Suit.
"Gathered Villains. We all have one thing in common, we hate the Justice League," Lex said. The villains that hated the Titans then yelled, except Slade. "And the Titans. We are gathered here to form a legion to rival the Justice League. The Legion of Doom." Behind him, the Ultra Humanite walked up.
"Many of us have experienced defeat from a group of heroes, especially the Justice League. The Justice League is too damn big. We will make a force to rival the League, and annihilate them and the Titans," the ape said.
"You can all sign up and receive your first tasks," Luthor said.

Titans Tower"BB, why do you always make TOFU when its your turn to cook. You know that's tasteless!" Cyborg yelled. The former athlete was chasing the green, shape shifting teen, Beast Boy, around the kitchen.
"Dude, I've been all those animals!" Beast Boy yelled. He turned into an ape and climbed up onto the roof. Beast Boy had received his powers when he was young, and had an illness that only an African Blue Monkey could survive. His parents turned him into one until he was better and then turned him back. The change had a side effect, and allowed Beast Boy to transform into any animal.
"Titans, we have new recruits!" Robin yelled. Raven, daughter of Trigon; Starfire, Princess of Tamaran; Beast Boy, story already explained; and Cyborg, the first almost all robot man.
In the hall were three heroes.
"This is Kid Flash," Robin Said.
"Hi," The Yellow costumed boy said.
"Superboy," Robin continued.
"Hey! I'm Supergirl's brother," Superboy said.
"And Wondergirl," Robin Finished.
"Hiya, I'm one of Wonder Woman's sisters," Wondergirl said. Then, an alarm went off. The lights flashed red, and everyone looked up on the screen. Superman was there.
"Titans," Superman said.
"Hey Uncle!" Superboy said.
"This is not the time for Heys, Superboy. There has been a series of mass crimes all over the world. Titans East was dispatched to take care of some of the criminals, but unfortunately, the twins died. The League has deployed every member, but it is still not enough. Titans, I want four of you to meet With Group Gamma in downtown San Francisco. I need four of you to go to Gotham City," Superman said.
"Understood," Robin said. The Titans had to listen to Superman, as he funded the Titans. "BB, Wondergirl, Superboy, and Raven. San Fran. Me, Star, Cyborg, and Kid Flash are going to Gotham.

Downtown GothamBatman, Green Arrow, and Elongated Man were having enough trouble with one villain. Four was too many. Joker, Toyman, Mad Mod, and Gorilla Grodd were destroyed half of Gotham. The T-Copter landed before Grodd had hit Arrow with a Car.
Cyborg started blasting the car Grodd was holding with his laser hand. Kid Flash ran circles around Joker. Robin and Starfire were fighting Toyman's Giant Mega Zord weapon. Batman assisted Robin and Starfire, with part of a destroyed street pole, but Toyman's T-Rex Sword destroyed the street pole.
Green Arrow then shot a punch-arrow at Grodd's nose which made him drop the car. Much worse, the car landed on Kid Flash. Elongated Man then captured Joker. Joker then fired his acid flower at Elongated Man, melting through his rubbery flesh.
"NOOO!" Elongated Man shouted then became mysteriously silent.
"Whew, I shoulda used that on Batman a long time ago," Joker then tried spraying again, but found there was no more, "That cost a fortune to buy!"
"Urgh. Superman's gonna be mad," Batman grunted, as he was Co-Chair of the Justice League.
Green Arrow then shot an electricity net arrow at Grodd, capturing him.
"Whew," Arrow said. Arrow then shot an Electric pulse arrow at Toyman's machine destroying it. Batman captured him with a good old-fashioned net. Robin helped Kid Flash up from under the car, and then punched Joker. Robin then whacked him with his stick. Batman then put handcuffs on Joker. All three villains were toted off in a league vehicle. The heroes got in the Javelin 12 and then awaited instructions from Global Command.
