Sorry for shit posting so long ago.
In the 1990s, I wrote a story where an unknown rival uses a (one way) magic wrestling belt to dispose of a (male) teenage wrestler in a gender bender. The attached letter (it is set before the widespread internet) told the spotlight character the belt is “something to help you win more contests”. Which to be fair, it will, just it will be Miss Teen Australia, not a boy’s wrestling contest.
