These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Base Breaker: Not the character, the writer, Devin Greyson, one of the main writers of his long run. She's either the cause of several majorly terrible story arcs and a massive Dork Age, or she's a decent writer who just wasn't writing at her best at the time.
Complete Monster: Quite a few. Dudley Soames when he becomes Torque and Blockbuster just to name a few.
Ensemble Darkhorse: DC Comics' official position is that he's the most beloved superhero in the community (yes, even moreso than Superman) and that almost any member of it would instantly drop what they were doing to help if he were in trouble.
He's this outside of comics as well. Dick Grayson routinely gets top marks in popularity polls, even beating out iconic characters like Superman and Batman himself.
Heartwarming Moments: In one issue of his self-titled series, Dick muses to himself about the differences between himself and Bruce. In the end, he concludes that if Bruce could go back in time and trade becoming Batman just to have his parents back, he would do so in a heartbeat. Dick admits to himself that, while he misses his parents terribly, he wouldn't trade being raised by Bruce for anything in the world.
My Real Daddy: Bob Kane is credited with creating Dick Grayson, with some credit also going to Bill Finger... but Nightwing was created by Marv Wolfman, who had exclusive rights to the character throughout his entire run on New Teen Titans. Chuck Dixon is then credited with developing Dick's solo career in the 1996 Nightwing title.
