Obsessed with the way Dick is just-so good of a parent that kids love him so much that they’ll just abandon their real parent to go to him instead.
Damian: No need to explain
Rose: literally talks about how Nightwing is so special and cool and how she wants to spend more time with him (I’ll upload the panel when I remember the comic). I think Slade bombed Bludhaven because he was mad Dick turned Rose away from him. Emotionally and ethically.
Jon: Superman literally calls Dick over when his son is feeling sad because Dick understands the kid so well and Jon loves him just as much.
Lian: Dick was the only person she was closest to after Roy. He called her princess and she was his second parent since her mom was in jail and also just because he treated her that way.
Gotham kids: When Dick takes care of people, they instantly bond to him and show him a level of respect that is hard to come by.
His son, Jake. Jake is a special case and my favorite because Kori actually left Dick to do her own superhero thing so Dick raised Jake by himself, as a single parent, with the help of Alfred. The devotion and mothering/fathering he did for Jake was reciprocated by such a loyalty I felt compelled to make this post.
