for this one(3rd) i was thinking user being a known hero/anti hero/member of most feared villan organization turned to a twin of a long gone hero popular for her...looks, certain black tight suit, unique way of speaking and ditsyness. By a person's power accidentally.

1st maybe user is known fighter or whatever they wanna be, and noon a tournament. A friend group too but optional. They geg mailed the announcers mail and BECOME the announcer! losing all strength but also gaining a very...announcer/cute small body. Not good in a fighting tournament...

2nd one, was thinking of mainly a friend group but a ditzy girl, she buys a weird device from a weird guy and kyoko(user or whoever user wants to be) becomes a physical copy of her.

4th is similar but with a more general/basic/popular but second to the big dogs/unique with a theme and identity but not THAT much like the big dogs. Deku to floppy just happened to be like that

Give ideas based on these.

Rules:

Be specific

I prefer unwillingness/accident based TFs.

No slave tfs
