This is showing up on blogs I frequent, and I think it’s relevant here. Alexander Macris has divided superhero origin stories into three types:
1. Ordinary person accidentally becomes extraordinary through chance.
2. Determined person becomes extraordinary through dedication and will.
3. A person born with extraordinary gifts lives up to his birthright.
He describes these three origin stories as “proletariat, bourgeoise, and aristocratic.” The examples he gives are interesting but not unassailable. For example, he holds Superman to be “aristocratic,” since he has superpowers on account of being an alien, but Superman is also a farm boy who learned values of honesty, honor, and hard work before moving to the big city, which would put him more-or-less into the “bourgeoise” category—and yet calling a farm boy “bourgeoise” sounds decidedly strange.
I wanted to add a fourth type of origin story, but John C. Wright beat me to it:
4. Ordinary person is selected to become extraordinary through the intervention of a higher power.
This is the origin story typical of magical girl warriors. Generally, they are ordinary schoolgirls selected by talking animals from space or from fairyland. They are frequently reluctant and would rather be ordinary girls, though there are exceptions.
Even those of the “deconstructive” brand of magical girl fall mostly into this category: Phantom Thief Jeanne, Revolutionary Girl Utena, Princess Tutu, and the girls of Magical Girl Raising Project are all selected by godlike powers, and even Madoka is harassed into a Faustian bargain, which is almost but not quite the same thing. What makes these girls different is simply that the powers who’ve selected them turn out to be infernal rather than higher.
By contrast, the typical cute witch falls into Macris’s third category: cute witches usually come to Earth from space or from fairyland and use their powers to help mankind.
Of course, some titles will change things up. Some magical girl warriors are also cute witches from fairyland, such as the Fairy Musketeers. And Sailor Moon falls into both categories, since she is an ordinary schoolgirl who receives her powers from a talking cat, but is also a reincarnated space princess and rightful ruler of the Solar System.
