ペル
Pell is one of the commanders of the Alabastan guard and the strongest fighter in Alabasta. He ate the Tori Tori no Mi, Model: Falcon, Bird Bird Fruit, Model Falcon, called the "Tweet Tweet Fruit" in the English anime) and thus can transform into a falcon, and has earned him the kickname "Peregrine Falcon Pell" due to his bird powers. The fruit is apparently one of five that have been discovered that give the user the ability to fly. Since the fruit is a Zoan type, he has 3 types of transformations meaning that he can turn into a falcon or a man/falcon hybrid, as well as maintain his natural human form.
