I've noticed almost all your edits consist of moving the Robin appearance from Supporting Characters to Featured Characters. While in some occasions it is understandable, half of those edits are no accurate following the context of the stories. In the recent edits to World's Finest, Robin appears much less than Batman and Superman, therefore he is a Supporting Character. It's all about context.
What I'm asking you is to verify with the story at hand that the move is justified. Otherwise don't move the appearances.
Yes, for a small part of the story. A featured Character is the main focus of the story. Someone who drives the story almost all the way from beginning to end. All other characters who appear in the middle of the story are supporting characters. People who are not the focus on by the primary storyline. Get it?
