Lily Enstomach is a female giant who ate the Mini-Mini Fruit and can shrink and grow her own body.
Lily was originally a female giant that traveled through the New World portion of the Grand Line with her famous pirate-chef father, Panz Fry. Her love of food and eating earned her the nickname, Lily the Glutton. Sometime during their adventures, Lily ate the Mini-Mini Devil Fruit. This caused her body to shrink to the few inches, but she also gained the power to shrink smaller or return to her giant size temperately.
After her father went missing, she stowed away on Marine ships and discovered her father was captured and would be taken to Impel Down through the Maubeugemour Sea. While Lily was hiding on a Marine ship in the Maubeugemour Sea, the ship shank in the violent weather. She was alone and waiting in an empty bottle for her father when a ship came from below and she crashed aboard.
Lily Enstomach is a supporting character in the One Piece series that was created by Eiichiro Oda. She's an anime filler character that made no appearance in the original manga that was the inspiration for the anime. The One Piece anime series first began airing in October 1999, and Lily wouldn't appear until the Z's Ambition Arc that began in Episode 575. These episodes directly tied into the twelfth film of the One Piece series, One Piece Film: Z.
Her first anime appearance was in One Piece - Episode 575 "Z's Ambition! Lily the Little Giant!". Her character in the Japanese series is voiced by Shizuka Ito, and the U.S. dub produced by FUNimation has yet to announce a voice actor.
Lily shrunk down to her smallest size aboard the Thousand Sunny ship of the Straw Hats, but she couldn't help but each much of her food. This is how she was discovered and they chased her down. Despite growing to her giant form, the captain, Luffy, defeated her and tossed her into the sea. However, they rescued her from drowning and weren't as violent as she thought. She told them about her plan to rescue her father, and they volunteered to help.
Lily was naturally born as a giant, and with that comes a natural born level of super strength. She's not afraid to fight and has been traveling with her father during his pirate adventures.
Lily has the powers of the Mini-Mini Devil Fruit. This is a Paramecia type that changed her body to cause her to shrink to a few inches tall, but this devil fruit also gives her the ability to alter her bodiy size at will. She can shrink as small as 5 millimeters, or even grow back to her original size of a giant. Even in her small size she retains much of her incredibly strength to lift a grown man with ease.
Lily's only known weapon is a large fork that she uses as a spear for both attack and defense. She can change the size of this fork in proportion with her own body. However, she also uses it to eat with.
