This was an idea i had as well where a superhero falls in love with her arch enemy and vice versa and then they kick ass together while the hero has to constantly make sure the villain stops being evil.
whose the villain whose the hero? is it obvious or the unexpected? Not gonna tell.

Jasmine Jennison ( in the blue) can control water and anything with water in it. the human body, mist, clouds, etc. Known as Lunar Flare.

Lenna R. Kroon ((in the pink and orange)) can stretch and contort her body in all different manners and shape shift into only people or things she has touched. She has no official super name yet as i can't think of a good one. suggestions are welcomed.
