One-Wheeled Wonder

A character that moves by balancing on one wheel or ball.

There are three subtypes:


 * Integrated unicycle
 * A character, usually a robot or Powered Armor, has a wheel at the bottom and a center of mass above the wheel.


 * Separate unicycle
 * The character but mounts a vehicle with one wheel.


 * Wheel is most of body
 * Center of mass is within the wheel, as if a separate unicycle were autonomous.

It doesn't include characters that move by rolling or spin-dashing.

Anime and Manga

 * Venus Wars has Battle Biking, a violet sport, that uses one-wheeled monobikes for a roller derby-ish fighting sport. The Killer Commandos, the team that the heroes are on, uses their bikes for to fight against Ishtar invaders.
 * Victory Gundam has the Einerad, which is nothing more than a wheel with a pair of cannons, a missile launcher and a place for a mobile suit to stand mounted on the unmoving center with no clear way for the driver to actually see in front of him. This is a series where everyone can fly. While the claim that Victory had intentionally stupid looking things as a jab against To Sell Toys executives remains unproven, it would certainly explain the Einerad.
 * Gundam Build Fighters's Ricardo Fellini, who sometimes uses the Meteor Hopper, a one-wheeled motorcycle for his Wing Gundam Fenice. After upgrading his Gundam to transform, he quits using this motorcycle.
 * Dragon Ball has Launch using a one-wheeled bike to rob a train in her first episode appearance.
