Maxim

The Ark Maxim (方舟マクシム) is Enel's colossal flying ark. It was built by Gan Fall's men for Enel.

Appearance
The ark contains a throne that is beneath a golden face and a large storage room. The gears and generators are quite large and it has a line of oars whose use wasn't shown. It has multiple rotors and propellers to help it fly.

Abilities
The Maxim is capable of flight, even in space. Enel's electrical energy is its main power supply while two hundred Jet Dials are used as a backup power supply to keep the ark in the air for an hour if something were to happen to the Ark's mechanism. Enel used the gold from the Shandora ruins as a conductor for his electricity.

Enel can use it to create massive lightning storms via a combination of chemical vats that produce storms clouds and his own lightning abilities. One of these thunderbolts is enough to burn down an entire village, and Enel can create a giant thundercloud that can destroy an entire island.

History
During the Skypiea arc the ship suffered a good bit of damage, although none was crippling to the vessel's ability to fly. After Enel's defeat at the hands of Monkey D. Luffy, the "God" departed to the moon on his ark, in hopes of finding his Endless Vearth. This leads to his mini arc, where the the Ark Maxim was implied to have been destroyed by the Space Pirates during a large explosion that Enel saw, though not confirmed.
