Canon things that we should not let fall into obscurity:
• Dick was an excellent basketball player and played on the school team
• Dick plays both the guitar AND the accordion
• Jason had a pet dog when he was itty bitty. The dog's name was Sparky
• Tim is a skater. He skateboards and is pretty damn good at it, both as Tim and Robin
• Tim and Bruce both like The Clash. Alfred is Britishly Offended by their music
•Jason loved books as a kid. To support this, Bruce had a mini library built right in his bedroom
•Alfred and Bruce collected first edition books ever since Bruce was a little kid. It's implied this tradition was also carried on with Bruce and Jason
•Damian steals items from his brothers. He's stolen a helmet from Jason, escrima sticks from Dick, possibly one of Tim's bo staffs and I'm 75% sure he's stolen one of his father's cowls
•Barry Allen's real name for a time was Barrence Allen.
•Tim was a boarding school kid. He spent the first half of his life in boarding schools and didn't go to a semi normal school until he moved in with Bruce and went to Gotham Academy.
•Tim did not drop out of high school, he was kicked out because his father did not pay the Brentwood boarding school tuition (because posh boarding schools don't let you attend if you have no means of paying or aren't there on scholarship). It's unclear if Tim ever finished high school or if he just got a GED.
•Correction!: After Brentwood, Tim did go back to a local high school. Unfortunately, he had to drop out again after Bruce died and Tim went on his infamous search. (Thanks everyone who pointed this out!)
•Cass is teaching herself how to read and gets very frustrated with it, but is stubbornly pushing through. We're very proud of her
•Duke has a Nest. He has his very own base of operations and it is stellar
•Steph's father was friends with Edward Nigma. The Riddler spent some time living in Steph's house with their family. They probably had to share a bathroom. (Imagine that chaos)
•Baby Steph dressed up in a cape and Super shirt and pretended to be Superman
•There are four members of the Dead Robin club: Jason, Damian, Steph, and Dick. He was once dead for about five minutes, killed by Lex Luthor before being rescusitated. Likewise, Steph's heart stopped before Leslie was able to revive her before squirrelling her away to Africa. Cass's nomination is up in the air as she has died but was not a Robin.
•Only Tim is member of the Thought Dead But Not Really Robin club
•Dick and Steph are members of both clubs and are considering getting punch cards.
•Duke is the lucky bastard to be part of neither club. He lives in terror of the day he gets a membership
•Damian tried to kill Victor Zsasz. He really thought he succeeded. But Victor survived and no one's really sure how, and the fact that Damian did his best to kill him is never mentioned again
•Steph can speak Swahili
•Roy Harper's original vice was heroin addiction due to being undercover. In New52 it was retconned into an alcohol addiction.
•Talia. Is. A. Good. Person. And. Morrison. Fucked. Her. Over.
•For a time, it was believed that Lady Shiva was Jason's birth mother
•It is unclear if Two Face has been disbarred from practicing law or not
Update: Sorry for any mistakes I made.
