Dick Grayson the ADHD Baddie
Because of his overall lack of executive function he exists off of cereal, frozen meals, and pure adrenaline.
Sometimes he tries to be a little creative in the kitchen but his impatience, and lack of attention span, often leads to disaster.
He likes a particular taco truck in Bludhaven, he has formed such a close relationship with the vendors that he has been invited to at least three quinceaneras in the last year.
Occasionally, he will run into Jason at the same taco truck and they'll have a rare meal together when Jason is up for it. These encounters usually consist of Dick yapping at Jason the entire time.
Dick CANNOT sit still. He needs to be in motion constantly, which has resulted in him shaking his leg every time he sits down and his preference for standing when taking public transport-- which he has to take A LOT because he frequently loses his keys-- but he doesn't mind because he loves chatting with strangers.
Because of his key-losing-habit he often has to enter his apartment or safehouses through the window.
He wears a wallet chain-- not for safety reasons, he is Nightwing after all-- but so he doesn't misplace that too.
He never spends money on himself but is generous with others even despite his lowball BPD salary.
His apartment would be completely empty, the way he grew up traveling with the circus often meant only having necessities, if not for the fact that he is extremely sentimental.
He keeps photos of all his friends on the walls and proudly shelves the gifts and mementos he has received over the years.
One of his favorite possessions is the first birthday gift he received from Tim, a scrapbook full of photos of Dick with various members of the Titans, Batman and Robin, as well as the two of them together.
Dick doesn't often spend much time at his apartment because he tends to feel lonely when he is by himself.
He tends to wear the same things repeatedly so his clothing is both slightly outdated and well-loved.
I imagine he probably still wears skinny jeans because he doesn't see much point in updating his wardrobe and he also prefers tighter clothing. Said skinny jeans would have many holes and patches in them from over the years due to both drunken and sober gymnast shenanigans.
He still wears the same converse that he wore back in his Teen Titan days (post growth spurt) because they are signed by all of the TT members in sharpie.
He wears friendship bracelets that he has received from friends, Raves, and concerts.
The culmination of all of these things together makes Dick a bit of a fashion disaster but he doesn't really care and his good looks make up for it.
