Falling Stars

A Fusion Fic can result in some pretty strange combinations of universes. Something like Falling Stars, however, takes this Up to Eleven On Drugs.

Taking the characters from Lucky Star and dumping them into the world of Fallout 3, Falling Stars (written by Tastychainsaws) pretty much throws a twist into your usual crossover fan fic. Konata becomes the Lone Wanderer, and Kagami and Tsukasa end up as her (initially) unwilling sidekicks. The results are not pretty.

It has been given a sequel (which is unfinished, and not written by the original author), which can be found here. Yet another sequel, also not by the original author, made to bridge the gap between the original story and the other sequel, can be found here. The author has also written a story on Minami and Kuroi's early years in the Enclave titled "Sigma".

Not to be confused with the BattleTech/My Little Pony Friendship Is Magic crossover with the same name.

This Fanfic provides examples of:

 * After the End: Obviously.
 * All There in the Manual: The author often tries to explain certain elements of Fallout 3 after every chapter for those unfamiliar with the game itself. He does it less later on.
 * All Just a Dream: Played with during the events in the Dunwich building. Poor Kagami...
 * Anti-Hero: Kagami builds up lots of evil karma as well as having to deal with drug addiction later on. She arguably becomes something of a Villain Protagonist near the end.
 * Anyone Can Die: Kinda comes with the Fallout Universe, where everybody can be killed. Tastychainsaws even had the guts to
 * Badass: By the end Konata, Kagami and even Tsukasa definitely count.
 * Berserk Button: Konata manages to push several of Kagami's buttons...
 * Boom! Headshot!: A Deathclaw loses his head.
 * Breaking the Fourth Wall: Konata does this a few times.
 * Break the Cutie: To the point where you may think Mohiro Kitoh wrote this. Then again, what did you expect to happen when you take characters who come close to being Trope Codifiers of Moe and dump them in a radioactive wasteland filled with mutant creatures?
 * Colonel Badass: Colonel Kuroi, in place of Colonel Autumn. Later she promotes herself to General.
 * Dark Fic: To some extent.
 * Decoy Protagonist: Konata may be following in the footsteps of the Lone Wanderer at first, but make no mistake, this is Kagami's story.
 * Deep-Immersion Gaming: Word of God implies that the whole story is derived from the Lucky Star characters doing playthrough(s) of Fallout 3, with some joking towards them moving onto Dragon Age: Origins. Then again the actual series does this sometimes.
 * Driven to Suicide:
 * It turns out that
 * Egopolis:
 * Go Out with a Smile:
 * Gorn: It is not rated M due to Lemon.
 * Special mentions to chapter 7 of Sigma, though. Tastychainsaws saw fit to actually warn his readers about the amount of gore in that chapter. This is the guy who tossed a tea-sipping all-girl high school pop music band into a Zombie Apocalypse with no second thoughts.
 * Jumping Off the Slippery Slope,
 * Justified Trope: The author attempts to justify certain gameplay elements, such as VATS being a shot of adrenaline from the Pip-Boy or how Stimpacks work.
 * Let's Split Up, Gang!: Done when the group finds Casey Smith's garage.
 * Mythology Gag:
 * Also,
 * No Periods, Period: Definitively averted.
 * Omnicidal Neutral:
 * Only Sane Man: Lampshaded by Kagami.
 * Our Vampires Are Different: Minami, who replaces Vance in the story.
 * Parental Abandonment: Every bit as much a plot point here as it was in Fallout 3.
 * Shell-Shocked Veteran: Kagami at the end.
 * Shout-Out: Plenty of them (we are dealing with Konata, after all).
 * Title Drop:
 * Took a Level In Badass: Tsukasa, after returning from Point Lookout.
 * Wall of Text: Due to issues with the author's word processor, this occurred at the end of Chapter 9, making it nearly unreadable. However, the author fixed this error and made the chapter actually readable.
 * Where Are They Now? Epilogue
 * You Gotta Have Blue Hair: Done with some word play, as certain characters are referred to as "blunette".
