Might as well begin one for [b]Ashes of Arkham[/b]. Might do ones for other fanfics, but this one will be updated as chapters are added.

[u]First for the fic as a whole.[/u]
Action Girl: Azumi and Jessica.
Alternative Character Interpretation:  The Arkhamverse!Batman is noticeabley more brutal than his DCAU counterpart.  However, this is more on the creator's part than ours.
Anti Hero: DCAU!Batman is a Type II. Azumi, Jessica, Arkham!Batman and to a degree Catwoman are Type IIIs.
Anti Villain: What Catwoman isn't as a Type III Anti Hero she is as a Type I of this.
Badass: Basically the entire protagonist ensemble, both canon and not.
Badass Abnormal: Scarecrow, as per normal now.
Badass Normal: DCAU!Batman, Arkhamverse!Batman, Arkhamverse!Catwoman, and Azumi Ian.
Batman Gambit: One is in action, yes, but it isn't by the Trope Namers. It's by [i]Azumi[/i].
Catgirl: Selina "Catwoman" Kyle and Jessica Mireu, in motif and literally respectively.
Classy Cat Burglar: Selina again.
Crapsack World: When you're in the Arkhamverse, you know that, at minimum, you will end up with many more bruises than you are used to.
Dark Action Girl: Catwoman.
Femme Fatale: Again Catwoman.
Goggles Do Something Unusual: Detective Vision, Helmet Mounted Displays, VISR, and Thief Vision.
Hey, it's That Voice!: In-universe. Kevin Conroy voices both Batmen, and Grey DeLisle voices both Catwoman and Azumi.
Lighter And Softer: Than the game itself. Very, [i]very[/i] slightly.
Massively Multiplayer Crossover: Of a sort. This is the most people working together on a fic, let along individual chapters, that has happened thus far.
Noble Demon: Catwoman.
Race Against The Clock: Azumi and the Batmen are trying to find out what Protocol 10 is before it is too late.
She Fu: Catwoman's fighting style.
Whip It Good: The catgirl duo.

[u]Prologue[/u]
Batman Cold Open: As per the opening of the game itself, though there are two in it this time.
Click Hello: The cliffhanger.
Embarrassing Nickname: "Catgirl" for Jessica, taking from the DCU itself.
Fish Out of Water: Jessica, in a sense.
Les Yay: Played for laughs. Catwoman teases Jessica about her looks, and Jessica has a hard time not looking at Selina's swinging behind.
Lovely Angels/Sword and Sorcerer: Kyle and Mireu begin a variant of these kinds of partnerships here.
Unusually Uninteresting Sight: Catwoman isn't that alarmed by Jess's looks, and up-front says she probably should have expected that eventually. Granted, she's from the DCU, and is friends with a Plant Person.

[i]Chapter 1[/i]
Acid Pool:  What Two-Face was going to drop Catwoman and Jess into.
Black and White Insanity:  Two-Face himself.
Faux Affably Evil: Julian Gregory "Calendar Man" Day rather politely tells Azumi about how he strangled a woman on Valentine's Day. Charming.
Badass In Distress: Jessica and Catwoman. They break themselves out.
Two Faced: The Trope Namer himself.
Stealth Hi/Bye: The Cliffhanger.
The Man In The Mirror Talks Back: Two-Face's two halves are identified separately.

[i]Chapter 2[/i]
Second Episode New Character: DCAU!Batman and Spiderman didn't show up in previous chapters at all.

[i]Chapter 3[/i]


[i]Chapter 4[/i]
Ain't No Rule: How Scarecrow takes down the Riddler's scheme.
Enemy Mine: Of a sort. Scarecrow leads Batman to Riddler's hideouts with signs.
He's Back: Scarecrow is back home. Watch out.
Incoming Ham: "The Scarecrow [i]lives[/i]!"
Mook Horror Show: Played by the master of horror himself.
Playful Hacker: The Riddler.
Refuge In Audacity: Scarecrow's solution to the Riddler's game.
Rule Of Funny: See Refuge in Audacity.
Troll: Edward "the Riddler" Nigma at your service.
