Alfred and the Tiny Attic Squatters
is a Danny Phantom and Batman crossover by Shynnohwen. They have also written Visitant Lights, Family Bonding And Other Perilous Pursuits, and The Misadventures Of Cosplay Man.
A de-aged Jazz, Danny and Dan, and Ellie (in reverse age order) are dropped into Gotham by Clockwork, and when they draw the attention of Batman they decide to hide... in the attic of Wayne Manor.
Meanwhile, Batman is frantically scouring the city for a daughter he had never known he had.
Alfred and the Tiny Attic Squatters contains examples of:
- Alternate Self: There are a number of characters from the DP universe that have counterparts in the DC universe.
- For the Batfamily, Bruce Wayne is the counterpart of Jack Fenton, and Jason is potentially Dan's and Damian's potentially Danny's.
- Colin Wilkes turns out to be Jazz's counterpart, as proven by when they crash into each other and exchange some flashes of memory.
- Superman's counterpart is Vlad, while Lancer the teacher is this for Lex Luthor.
- Sheila Haywood is this for Maddie Fenton.
- Asshole Victim: Jazz kills the Joker, but even considering everything that he'd done before, he brought it upon himself by attacking the siblings unprovoked after accidentally coming across them. They have also killed off Black Mask, Zzazz, Professor Pyg, and Dan has their gang killing off assorted murders and rapists.
- The Baby Trap: The Batfamily concludes Jazz being a Chocolate Baby prevented Sheila Haywood from identifying her as Bruce's biological daughter, since a lot of women would jump on the opportunity to bear a millionaire's child in order to claim a pension.
- Big Sister Instinct: Jazz has this in spades, with an instinct to take charge of other kids. Due to how she has been put into a younger body however, it looks like she is acting older than she is with Damian and doing the same to him automatically.
- Benevolent Boss: Granted, it is a low bar when you are being compared to Joker, but the sheer degree to which Jazz has devoted herself to getting better lives for her gang has made them even more loyal.
- Chocolate Baby: Wonder Woman expresses disbelief over Jazz's potential parentage, since she's a redhead but her father is black-haired and her mother very much a blonde. Only for Bruce to admit his maternal grandfather and paternal grandmother were redheaded, so as long as the gene for red hair was lurking in Sheila Haywood's ancestry, Jazz isn't impossible, merely unlikely.
- Dead Person Impersonation: Or a variation. Jazz and her siblings fake the paperwork so that she is Sheila Haywood's biological daughter, which genetically she is. They do so though under the assumption though she is a normal person who died abroad, and then further muddy the water by making it looking like an imposter took her place, including filing tax documents for her since Haywood's death. All while being blissfully unaware of Haywood's connection to the Bat-Family.
- Didn't Think This Through: The Evans siblings all 'know' that Batman is dating Bruce Wayne, however their whole fake backstory to throw off investigators, and interactions with the crime-boss furry and his underlings, and their interactions with the Wayne family, are all based upon the underlying assumption that neither party would share information with each other, particularly about her. The fact that in fact Batman is Bruce Wayne only means this information is being shared even more completely.
- The Dragon: Dan to Jazz within the gang...not that he will tell her. He handles weeding out who is loyal or not, killing off the scum of the streets, establishing dominance as necessary, and very much being her much more brutal top lieutenant handling the actual criminal matters. To the point Red Hood is furious at the indications someone is using his newly discovered half-sister as a figurehead.
- Dramatic Irony: A lot of the story's humor comes from the characters making assumptions that the audience knows are flawed.
- Fountain of Youth: When Clockwork sent the Fenton siblings to the DC universe, he de-ages them.
- Lethal Chef: Dani and Colin cannot cook to save their lives, while Jazz and Danny are outright bio-hazards when they cook. To the point that after hearing some of her examples, Alfred has preemptively banned her from so much as entering his kitchen. Given Bruce is also a terrible cook, if not as bad as Jazz, it is assumed it is genetic. Although Dante is actually a Supreme Chef despite originally having been the latter, having spared people in his original timeline if they taught him how to cook as a hobby.
- Look Behind You:
- When Bruce first came across Jazz stealing his Batmobile wheels, Jazz escaped him by yelling that there were two of Batman, and in the ten seconds Bruce turned to look Jazz managed to vanish. Bruce spends ten minutes negotiating with Barbara not to tell anything that he fell for that.
- After killing the Joker and being discovered by Nightwing and Red Hood disposing of the body, she gets away by pointing behind them and shouting "Batman".
- Necessarily Evil: Clockwork's motives for sending the kids to Gotham, even if he loves them as his own children and is extremely upset how much they will hate him for it.
- Parental Favouritism: Sibling variant — Damian deems he likes Jazz the best among his many brothers and sisters in spite of barely knowing her because she's blood-related to him, and because her being a girl means she's not a threat to his plans to become Batman's heir.
- Pint-Sized Powerhouse: Jazz, Dani, Dan, and Danny are all this in spades, with a sizeable chunk of Gotham's supervillains already dead by their hands.
- Right Under Their Noses: Hiding from Batman, and thinking that he and Bruce are in a relationship, the de-aged Fentons choose to hide right in the attic of Wayne Manor, the last place he'd ever think to look. And they are largely right, with only Alfred catching on.
- Siblings Wanted: Damian, but with the caveat he wants biological siblings since his mother and grandfather indoctrinated him to believe blood family was the best and only choice so he cannot fully bring himself to be satisfied with Bruce's adopted children. When he learns Jazz is Bruce's illegitimate daughter, he's ecstatic and immediately starts planning how to best approach her and obtain her trust.
- Troll: After the kids vanish, Vlad goes mental looking for them, and causes a lot of trouble for the Observants. Clockwork can barely hide how amused he is when telling one that he won't stop the older halfa.
- Undying Loyalty: Jazz's gang towards her, with a carrot and stick approach. They love her for how much she strives to make better lives for them all, and they are entirely justifiably terrified of her unholy and extremely protective younger siblings.
- Wham Episode:
- Chapter 5 has the Batfamily discover that Jazz is also Jason's half-sister. The readers know the truth, but for them this sends the vigilantes into a spiral trying to work things out.
- Chapter 6 reveals that Jazz had actually died before Clockwork reversed things and sent them to the DC Universe, and if he hadn't Dante, Danny, and Ellie would have gone on a rampage that would have put Dante's original one to shame.
- Year Inside, Hour Outside: According to Clockwork, he'll eventually bring the de-aged Fentons back to their own world just a few minutes after they left.
- You Kill It, You Bought It: After Jazz killed the Joker, his men started wanting to follow her, and her attempts to turn them down and get them to seek legitimate employ only made them start using said businesses as fronts, and resulting in a chain of events that makes them even more loyal.
