Becoming something different

What if instead of Jim being chosen as the hunter it was in fact a young girl, Claire Nunez. And what if Jim wasn't in fact a human.

This story is a planned rewrite of most of Trollhunters, Jim in this story is a changeling and will have his own perspective but overall Claire is going to be the main character. Naturally it will result to Claire x Jim and I'm not going to do slow burn but there relationship will naturally be more rocky in this one due to the more secretive nature going on between them
