Miss Valentine works alongside Mr. 5 as part of Baroque Works. Her Devil Fruit ability, the Kilo Kilo Fruit, lets her adjust her weight anywhere from 1 to 10,000 kilograms—basically giving her total control over how heavy or light she is. In combat, she exploits this in two main ways: cranking her weight up to devastating levels to crush enemies, or going super light so she can float and glide through the air using an umbrella. It's a pretty versatile power when you think about it.
