Aaron: "In fact, Moses, when did you start caring about slaves? Was it when you found out you WERE one of us?" - The Prince of Egypt
Kyle: "Wow, that's a little ironic, isn't it?"
Cartman: "What do you mean, Kyle?"
Kyle: "Well, all last week you were ripping on ginger kids and now you ARE one." - "Ginger Kids" South Park
was burned down by barbarians when she was a baby, resulting in a deeply-set hatred of them into her adult life - until the village elder informs her that her parents were barbarians!
Alternately, Bob, who lives in a society fueled by a scum labor class not worthy to lick his feet, rubs the phlebutonium the wrong way and is transformed himself into a laborer.
Shake and bake it however you like, the story's the same. Carol hates, dislikes, or was imbibed with long-standing prejudices from the day she was born against some class of society, only to turn into one herself. Carol gets over her original feelings, lessons are learned about being accepting of other people, Carol may
or may not
return to her original form by the end of the show, and she more than likely had some fun and heart-warming moments
in the process.
This trope does not work if Dave always knew he was from the oppressed culture. The whole point of this trope is that Eleanor does not care, becomes one, THEN cares because it directly affects her.
Keep in mind that the transformation is not necessarily down the social ladder. Consider Frank, a happy-go-lucky street urchin who takes orders from no one
only to discover he's the son of a duke. Or Gabrielle, who is established as a modern hippy busking on street corners and loathes politicians and corporations just before she magically or scientifically
switches places with the president's daughter.
CAN have unfortunate implications
in that the character treats these people like shit and tolerates or accepts their persecution up until the point the abuse is directed at them. Remember kids, the violent, mental, or emotional toture of a race of human beings is tolerable so long as you are not a member of that race.
Side note: This trope enters a shade of grey when you consider exactly what a "transformation" means. Does it include becoming so immersed in the culture that you become one
as is popular in so many Native American novels and films? This troper would like to discuss.
The Prince of Egypt
has the page quote. Moses in this version was not told he was Hebrew until well into his adult life. He had never even noticed the terrible suffering of his people until he knew he was one, banishes himself, and inevitably (spoilers!) lets his people go.
This trope does not apply to the original Old Testament story because in that version Moses always knew he was not Egyptian.
Cartman from South Park
in the episode "Ginger Kids." Also the page quote. Cartman spends all week telling everyone that ginger kids are soulless vampires. Pissed at him, Kyle, Stan, and Kenny put makeup on him in his sleep so that he appears to be ginger. Cartman, being a dumbass, is completely convinced he really is ginger and starts a revolution of ginger kids to purge the world of non-gingers. Guess what happens next.
