Maxine Celestia/Abilities and Powers

Navigational and Cartography Expertise
Being the assigned navigator of the Insane Pirates, Maxine is responsible for evaluating the direction that the ship goes as they sail further into the sea. She's also a talented cartographer, to the point where Arlong considered her skills on par with the fishmen "superiority" since they were superior to any fishman's. When Stelar destroys her room in the Tears of the Navigator arc, maps of both bathymetric and geographic nature were seen, indicating Maxine has a wide variety of cartographic skills.

Physical Abilities
After Dan's death, she found the motivation to become stronger, so she can protect her next time she's alive. So it wouldn't be her fault. Thanks to her son arriving on the ship, he got her books on Rokushiki, and Black Leg Style. As of now, it is unaware if Maxine has mastered all of the Black Leg kicks. But one thing is for sure. She has not fully mastered Rokushiki. She only knows Rankyaku, Tekkai, Shigan, and Soru. She also seems to know Geppo, too.

Art of Weather
Maxine's fighting style focuses mainly on the manipulation of the weather of her surroundings, also known as the "Art of Weather". Which combined with her extensive knowledge of the oceanography and weather systems, can also be used for devastating results.

Multiple Weapon Transformations
Granted a serum by Ace, and partnering up with Daniella for this, she has the ability to turn into multiple weapons, and can do this freely, and quickly. Such as a chainscythe, a blade, a smokebomb (only for Maxine to use her Dummy Star attack to confuse the opponent), and more. She can also use a series of umbrakinetic abilities powered by the Uncanny Sword.

Other Techniques

 * For weaponry purposes, after Dan uses the smoke bomb attack, Maxine immediately goes into her Dummy Star mode, which makes her look exactly like Daniella, to fool the opponent.
 * Due to her insane background, she SOMETIMES goes into a dark form, known as "Lunatic's Reign" (shown in the Marineford Arc when Dan and Grenjo died).
