Hi! I'm a long time lurker and I've had this idea rattling around in my head for months now. I would love to see how you and others add to this!
Based on Rainbolt (Geoguesser)
The Fenton siblings have to hide in Gotham when (insert bad reveal scenario here). Dani starts getting antsy when she can't follow her obsession for travel.
Dani starts playing Geoguesser on Jazz's suggestion. It works, especially when she gains a following on (insert twitch knock-off here). People start sending her photos so she can try to find where it was taken and she gets every one correct. She starts doing these over the weekend so she can still play the actual game.
Steph and Cass found the channel first. They thought it could be staged, but then Cass sent in a picture she took in China and it showed up on the next stream. BeenThereSeenThat (the name Dani gave her channel) looked at the picture and lit up.
"I've actually been there! Two years ago, there's this little shop that sneaks leftovers to street kids near this shot. Might be right behind the photographer actually!"
Then she opens the map and zooms in immediately on the little shop Cass had been eating at when she took the picture.
After this, Steph started talking about the streamer with the other bats. Soon they were all sending in pictures from more and more obscure areas. There were a few she claims to have actually been to, but most she had been to the general area and picked up on the traits.
Eventually she was getting submissions from all the younger heroes.
Dani does joint streams with her brother, Danny (Dying4Space), where he finds locations based on the view of the night sky. He geeks out so hard when one of the pictures was taken from space (Jon had taken it to send as an 'I see you' joke to Damian from the watchtower).
When Dani starts getting haters, Danny has her make Tucker a mod (1kn0wwh3r3y0ul1v3 (iknowwhereyoulive in 1337 speak)). He starts dming people with their ip address, coordinates, and legal name when they harass his bro's little sister. Tucker is having the time of his life.
Idk where to take this, maybe Danny says the coordinates of the watchtower and Batman takes it as a threat, maybe Dani is doing a stream when Jazz gets taken by a rogue and she locates them from a cracked window in the background. All I know is I want Bruce to begrudgingly respect these kids while thinking they're a threat.
(I just had this image of Dani looking at a picture of some random dirt road and going "Oh, I know that dirt! That's Tasmanian dirt!")
I love the idea that Dani and Danny get so good at knowing where things are on earth because they're going everywhere for ghost shit and get the attention from other heroes for it.
