Is riddler being touch averse an actual thing in the comics or just a really popular headcanon? (I haven't read a lot of comics yet 💔)
hm... from what ive read (and keep in mind i havent read everything yet so there could be instances im unaware of, or just forgetting lol), the only explicit example of him being touch averse is in his year of the villain issue:
i will say though, i think a lot of popular headcanons for him are... eh... but i actually think this one makes sense! ive talked about this before but edward's control issues arent really about other people, but specifically about controlling when things are going to happen to him. i think it totally tracks that he wouldnt like casual physical contact, at least from people he hasnt initiated it with first. also, worlds most autistic supervillain.
