1. An feeble attempt made by story or character writers to renew interest in a dying media franchise by giving a character an uninteresting or useless trait which adds little no depth to their character, and usually used as a measure to conceal their impending failure or as an effort to bring diversity to a whitewash cast of characters.

Ironically, even though sales were peak for the series during this time, in 2007, Harry Potter writer J.K. Rowling revealed the sexuality of book character Dumbledore as being gay with an ass-pull wizard, receiving some backlash readers and fans alike arguing that she gave no real depth to his character up until the storyboarding of "Fantastic Beasts: The Crimes of Grindlewalde"

2. Taking definition 1 and following through with it because you managed to gain or already had enough traction to actually continue your franchise and write a full filling and deep story for such a character.
Example 1.
Guy 1: Bro, did you hear that news about Soldier from Overwatch being gay?
Guy 2: Yeah man, they pulled a fucking JK Rowling because they couldn't save their toxic community and gaming league, or nerf their fucking characters.
Guy 1: I stopped playing after they added that retarded hamster anyway.

Example 2.
Guy 1: Did you watch the last episode of Adventure Time?
Guy 2: Nah, I heard they pulled a JK Rowling by making Princess Bubblegum and Marceline lesbians.
Guy 1: They actually made a decent storyboard with their romance and the aftermath overall in the New seasons.
Guy 2: Alright, might give it a watch.
