!!The comic books provides examples of:

* [[WriterRevolt Artist Revolt]]: In the original Chuck Dixon run, the script for the now infamous LesYay moment of Black Canary and Oracle meeting for the first time included a note by Dixon that "We’re going for [[PietaPlagiarism The Pieta]] as opposed to anything that HINTS of the sexual. This scene is apparently RIPE for misinterpretation (or [=OVERinterpretation=].) by some of our readers." The result?

** Gail has said that after using her in several guest appearances, she had wanted to add Vixen to the book's main cast, but was not permitted to by her editors.
** Gail had written on-line that [[Comicbook/{{Batgirl}} Cassandra Cain]], the second Batgirl, was scheduled to appear in an upcoming arc of the relaunch. However, behind-the-scenes issues have resulted in her continued absence, [[http://www.606studios.com/bendisboard/showpost.php?p=7631969&postcount=8 much to Gail's annoyance]]. It eventually turned out that the character was being used in Creator/GrantMorrison's ''[[GrantMorrisonsBatman Batman Inc.]]'' event, preventing her from showing up in BOP.
* WhatCouldHaveBeen: There was once a plan for the Birds of Prey to appear in an episode of ''JusticeLeagueUnlimited'' with a BroadStrokes recreation of their history. Barbara Gordon, as Batgirl, would be hospitalized while on a mission and forbidden by Batman from pursuing the matter further. However, instead of letting the matter rest she would contact Black Canary and Huntress and, while guiding them over the radio, would use their help to finish the mission. Unfortunately, the Bat-Embargo, which was a moratorium on using Batman related characters in JLU due to conflicts with both ''WesternAnimation/TheBatman'' and ''Film/BatmanBegins'', meant that Barbara could not be included and the episode was re-written into ''Double Date''. While still involving Canary and Huntress, it featured the addition of GreenArrow and TheQuestion and focused on the two pairs (Canary/Arrow and Huntress/Question) as they worked against one another.
