Maui's powers and abilities
Maui possesses extreme superhuman strength in both his arm and leg muscles. The latter allows him to jump significant heights that end with damaging land. Maui's incredible superhuman strength allowed him to perform impossible feats such as singlehandedly dredging up islands, lassoing the sun, and even pushing up the sky. His strength also lies in his lungs, as he can produce massive gusts of wind to clear a path before or surrounding him; he apparently uses this ability to harness the breeze in the world's air.
Since becoming a demigod, Maui is virtually immortal, looking the same in the present as he did one thousand years ago. This immortality is likely how he survived on a desert island in that length of time with little or no food or freshwater, and allows him to survive attacks from monsters and other deities that would greatly injure or kill a normal person.
Fish Hook proficiency
Maui's most powerful abilities come from his mighty fish hook, which allows him to shapeshift into a wide array of animals, from insects to whales. This proves to be an extremely useful asset, as Maui's quick changes from massive to pint-sized creatures prevent his enemies from keeping up and laying an attack. The fish hook glows with a blue (purple, if broken) energy when in use, and is strong enough to shatter stone and cause severe damage to deities. Because it was created by the gods, however, it can be just as easily destroyed by a deity. Fortunately, it will take more than one extreme blow to completely destroy the weapon. Maui tends to combine the strength of his muscles and his hook to perform acts such as pulling islands from the sea and lassoing the sun. Without his hook, however, Maui cannot shapeshift. He must also swing the hook a certain way to transform into the desired animal, as evidenced during his fight with Tamatoa. Although he would still have his strength, Maui is considerably less powerful when stripped of his magic weapon, and therefore vulnerable to enemies.
Illusions as seen is when singing, he was able to make cartoony hallucinations to distract Moana and take her boat.
With his hook, Maui is able to shapeshift into anything he can imagine, though mostly just animals.
Another significant trait of Maui is his animated tattoos plastered throughout his skin. The tattoos depict Maui's various exploits and accomplishments. New tattoos magically appear moments after a new milestone has been reached; as Maui explained, they must be earned. All of the tattoos are animated, but one stands out from the rest: Mini Maui. Mini Maui is a tattooed depiction of the actual Maui and acts as the latter's conscience, biggest supporter, and best friend. They communicate with each other often, and share a loving bond, though their conflicting levels of morality causes them to clash on occasion (with Maui being mischievous and Mini Maui being completely benevolent).
