Superman: "Bruce, tell me again why this arm is so important."
Batman: "Because it came from another dimension."
A desperate move by Kakashi sends the rookies into another dimension, revealing a world crisis for both the Justice League and the Teen Titans.Essentially runs off the premise that Kakashi's MS technique Kamui sends things to the DC universe. This gets out of hand when he accidentally sends the Konoha 11 plus Team Hebi to the DC world. The Justice League has to keep their rowdy visitors in line while trying to figure out a way to send them home. Spectre and a god-powered Luthor are also involved…If you love the rookie twelve, this is the fic for you. Every one of them gets a crowning moment of awesome (yes, even Ten-Ten; ESPECIALLY Ten-Ten). The story is set in the somewhat broken continuity of the DCAU, but numerous characters from the larger DC universe (and from outside of it) make cameo appearances or more. At over 300,000 words, its a long read, but worth it. NaruHina is part of the story, but it is a minor part and shouldn't turn you away from this excellent fic. Now complete.Can be read here. It can be read in Spanish here.
Tropes for this story include:
Alternate Universe: In Story; The main twelve of Konoha + Sasuke's Hebi group get caught in Kakashi's Sharingan Warping Technique. The result is they end up scattered about the DC universe.
The Spectre tries to do this with Kyuubi and Trigon but the latter basically laughs in his face and the former only agrees after it's pointed out that Luthor could Body Surf Naruto and take control of him
Eye Scream: Sasuke loses his left eye in the fight with Kyuubi Naruto
Later Neji shoots Bizarro right in the eye with a Blue Kryptonite arrow.
Also later Luthor/Darkseid rips out Kakashi's Sharingan.
Flat Earth Atheist: Mr. Terrific insists there's a logical explanation for all the supernatural events going on in the story, to the annoyance of several characters, particularly Deadman and Blue Devil.
For Want of a Nail: A chapter with Karin as the viewpoint character reveals that in this version of the Naruto story, Sasuke didn't abandon Juugo and Suigetsu during the attack on the Kages, which in turn lead to Taka taking down Danzo and leaving the area before Sakura could reach them. It's never suggested to be the case, but this may have been what eventually led to the Kakashi led mission to take down Sasuke, and in turn the events of the story.
Heroic BSOD: Mr. Terrific has a small one when Hinata unwittingly challenges his Arbitrary Skepticism by revealing details about one of his experiences with The Spectre she should, in theory, have no way of knowing.
Human Aliens: A good portion of the DC heroes, obviously. Naji lampshades this as he discusses with John Stewart while he and Rock Lee are given a tour of Oa.
Neural Implanting: Martian Manhunter clears up the communication problem for most of the Konoha team with his telepathy this way.
Shikamaru, having been in captivity for months, is unfortunate enough to get his English dictionary from Lex Luthor. He's not a fan.
Nice Job Breaking It, Hero: Kakashi finally decides to teleport himself (and Gai) to The DCAU, and appears right in front of Lex Luthor, who rips the Mangekyou Sharingan out of his head and uses it to complete The Anti-Life Equation.
Poor Communication Kills: Until J'onn uses his telepathy to implant the English language into their heads, the Rookie Twelve can only speak authentic Japanese. Much conflict initially ensues because neither party literally understands the other.
Refuge in Audacity: To keep word from getting out about Huntress' pregnancy, Question destroys her and his latest blood samples (in full view of Mr. Terrific and Green Arrow) and asks where the medical records are kept. After Terrific tells him, warning him only to tell Batman he's deleting files again. Why? Because he told them it's a safeguard against a Mayan conspiracy, and it's Question.
It takes a lot to convince Sai that he's not in a genjutsu.
Shout-Out: If you look closely during Ino's psychic breakdown, you'll notice several characters with their own connections to the mind...
Smart People Play Chess: Shikamaru vs. Lex Luthor, frequently. At the ending, Shikamaru vs. the Goddamned Batman. Just when Batman thinks he won without Shikamaru noticing, it turns out that Batman already lost.
This Is Reality: When surfing the internet, Beast Boy introduces the concept of fanfiction to Kiba. When Kiba asks him if there are any fanfics of himself, Beast Boy points out that of course there isn't, because he's real, and that would be creepy.
"Alex, as you get older, you'll learn everyone suffers, and everyone thinks that they suffer alone. Even if they share their troubles with others, they think their own brand of sorrow is special and incomprehensible by anyone else. They feel like… like little dots. Like little, isolated dots of suffering, completely separate."
"And what so few people understand is that they don't HAVE to be that way. They don't understand how to USE that suffering, to use it to understand others and to help others. The dots don't like to reach out to other dots, they don't try to connect. As minister, that's part of my job. To reach out to the heartaches in the pew and bring them into contact with each other. And, while I'm at it, to try and guess at the order to the dots. To… connect the dots, as it were, and see the overarching pattern to it all."
Unusually Uninteresting Sight: Robin is completely unmoved when Sasuke forces him to relive his parents' deaths via Tsukuyomi because a whole bunch of other villains with Mind Rape-based powers have done the same thing before.
