I've been reading this duo so obsessively, so I'm finally going to work on a reclist of all Dick + Damian stuff ever (or at least, all Dick + Damian things that I have found on the internet in my long hours of stalking that are of long and decent quality)
These are non fic but
These twitter RPs with Batbros and Robinception are the most awesome Dick/Damian snippets I've ever read. You can find them logged HERE (Start with ones at the bottom of the page). Just note IA means in action like words the characters are physically speaking out. Most posts are meant to be read from top to bottom. These aren't just normal normal-life bantering, they actually are going on missions, training, etc! Give it a try, I never regretted doing so.
Also, the AskDickandDamian tumblr is a wonderful combination of great art and good characterization where Dick and Damian answer viewer-submitted questions. CHECK IT OUT DOITDOITDOIT
AND NOW FOR SOME ART RECS
Dick loves Damian, Damian is not amused (especially when trying to confess his insecurity)
Damian slips up, Dick finds it adorable, Damian is STILL not amused
Damian loves kitties, Dick wants to be loved
HUGS, HUGS FOREVER
Summary: Damian discovers something that has him unsettled, so he consults Dick about it
My Comments: This is all sorts of brilliant and d'aww
Title: Dick hugs are the best on bad days
Summary: Refer to title
My Comments: lfjasd;lfkjasldfj; SOCUTE
Title: A Renegade Knight
Summary: Dick Grayson has stepped down from Batman and become Nightwing again. But when Red Hood is attacked by a villain identified as Renegade, how will the Batfamily react? And what is Deathstroke up to this time?
My Comments: Admittedly, this is more Dick-centric than Dick+Damian centric, but this is my goddamn "THE REBOOT IS A BUNCH OF BS THIS IS MY NEW HEADCANNON" fic and the Dick+Damian interaction in there is nice
Title: Brave New World
Summary: Damian Wayne ends up in the YJ-verse
My Comments: One of the few awesome long fics with Damian ending up in the YJ verse
Title: Pawn to Rook
Summary: Bruce is back and Damian is not happy about being usurped by Tim. Dick tries to stay out of it... then doesn't.
My Comments: It's interesting to just see the development going on here
Title: Who Else to Hold as the World Falls Down?
Summary: Post apocalyptic AU, Dick made his way towards them in a whirlwind of blood and gore, screaming for his littlest brother
My Comments: MY HEART ;__;
Title: All Due Honor
Summary: If it came down to a choice between his father and Grayson, there’s no question where his loyalty would lie, except Damian has no clue.
My Comments: Really short, but I love the undertone and message
Title: To break and mold
Summary: AU WiP where Dick is actually the younger sibling adopted by Bruce Wayne and Damian is hostile.
My Comments: It's an interesting start, but I've given up on it being updated :C
Warnings: Slash, smut in part 2
Summary: Dick needs to talk things over with Damian so he can move on. The first thing he needs to establish is whether or not the whole affair was only in his own imagination.
My Comments: This is older!Damian for those uncomfortable with young Damian.
Warnings: Slash, daaark
Summary: Damian has Dick marked for his own, when he grows up, and lets no one come between them. Damian's as young as you feel comfortable with; and Dick is unaware of his "little brother's" feelings.
My Comments: Gives me the creepy shivers
Title: I'm Not a Juvenile Delinquent
Warnings: Slash, Teacher/Student relationship (Damian is...somewhere around underaged), slight lemon in part 3
Summary: The year is 1958, Dick Grayson is a beatnik history teacher and Damian is a brooding outsider come to shake up all the squares, jocks, hep-cats and kittens. Crazy man, craaazy.
My Comments: So I usually don't go for school AUs. But this one is pretty well done and I always love the banter between the two. If you don't like slash, you can still read chapter 1 as relatively unslash-y
Title: Tonight I Sleep on a Bed of Nails
Warnings: Slash, mentions of sex
Summary: Tim confronts Damian about how to deal with an unrequited crush on Dick Grayson (he's been there). Of course, Damian always gets what he wants. Even if it's a long road to winning over his crush.
My comments: There's also some Tim/Other here and Tim/Dick but not major.
Title: Extensive Research
Warnings: Minor slash/UST
Summary: Various scenes as Damian grows older and Grayson grows…interesting.
My comments: There's lots of d'aww in this one. Even if you don't like slash, the relationship between the two is really caught well here
Warnings: Slash, WiP
Summary: Prince Damian al Ghul receives a gift in the form of a slave named Richard.
My Comments: I kinda didn't like the Jason/Dick side relationship here, but the writing is good. Damian and Dick's interactions are slow-building
Title: Business Before Pleasure
Warnings: Slash, minor smut in future chapters, a side of Bruce/Jason and Tim/Kon
Summary: Damian's observation that Dick likes to be tied up leads to the Wayne brothers starting a superhero line of sex toys (made by superheros FOR superheros). Batfamily bonding is had...with plenty of dysfunction
My Comments: This fic is awesome, because not only does it have bat!bros (kinda) getting along, the writing is just brilliant. Also, there is strip poker night and breakdowns, who doesn't love that?
Title: Sixth Time's the Charm
Summary: Five times Damian hit on Dick and Dick was oblivious and one time it worked. Featuring hormones, fluff, the traditional Batman/Robin breakup fight, Tim being all-knowing, and a terrible superhero name.
My Comments: Fairly enjoyable read :)
You know what, I think Miss Synph in general has a ton of well written Dick/Damian slash so I'll just rec her in general
Also OutoftheCavern on Tumblr also writes a bit of Dick/Damian
Also these are just more YJ fic with Dick and Damian. I must find them ALL
Dick has his older siblings visit him after injury
...wait goddamn I lost the other 2. UGHSDLKFJS:KDF
There's at least 3-4 more I know of. One was pretty good with Damian visiting Dick and having a pseudo dub-con relationship with him. Sadly, my bookmark folder is so deep and scary and my tags are like "f;alksjdf;laksjdf"
