I got bored so: here is Info Dropper (ID) in civilian clothing. As a hero, they wear a black jacket and a shirt that has a lot of pockets full of stuff and have a black facemask.
Aizawa- depending on story may have dared for a few months or may have only dated once.
Midnight- experimentation (ID likes women its decided but neither are into each other like that)
Oboro- two dates but both had no feelings and figured they were more chaos siblings then not.
Tensei- dated for years until a messy break up.
Sara- their ex-fiance who is a villain. They do not want to talk about it thanks.
Only living bio family member is Squirt, their younger brother. He’s 25 and ID cared for him after their parents deaths.
Their adopted daughter/mentee/sidekick Aria Elric who takes the name Statistica.
ID’s Quirk is called Info Drop where if they someone’s name or any name they themselves have accepted as their own, they will gain information on said person. It's usually 5 things ID did not know at the time.
This does not work on animals which is why they are really good friends with Nezu.
As such, ID has developed the habit of assigning nicknames to people so their Quirk doesn't constantly activate.
ID was mentored by Nezu for a while and considers him a friend.
ID has the hero name Goblin they use when working as a member of the Fae Court, an international hero group.
ID eventually leaves the group to become a teacher at UA no matter what, where they work as the theory heroics teacher.
ID is in love with Tensei and never stopped no matter what.
ID actually is a lot more powerful then they let on. They prefer to keep quiet about that, more so after a forced Quirk evolution.
Squirt (their brother) is selectively mute. He does not use his legal name ever due to trauma.
