Pio Oh

Pio Oh (오피오) is the youngest of the Oh siblings who became a Biklonaut at the same time as his older sister Mio. His sysop is Shade, has piloted the Scorpio Clone, and currently pilots the Mammoth Clone.

Pio is shy and reserved, but has a pure heart. As a young child with hope that the world can be a better place, he is proud of his status as a Biklonaut even without fame or fortune, satisfied with the simple task of doing good. This puts him in some conflict with his brother Gio, whom he wishes would obsess over money much less.

Arsenal
Pio's Beginner suit and Action Bike are both based off of the Scorpio clone, making them black. Notably, the front armor of Pio's Action Bike is shaped like the head of the Scorpio clone, unlike the more standard motorcycle-like designs of the Action Bikes of his siblings. With the training wheels equipped, the Action Bike's Cycling creates four energy wheels from each wheel of the bicycle, which home in on multiple targets. Once the wheels are removed, the Cycling turns two energy wheels into some sort of highly-explosive butterfly unit.  Pio's Intermediate suit and Action Bike are now derived from the Mammoth clone. This doesn't make either blue, however; the suit itself has an orange theme to it and the Action Bike is still black but with orange accents. The colors of Pio's gear is likely based off of the Mammoth clone's orange and black emblem instead of the clone itself.

So far, Pio has not been shown to have gained an additional weapon of his own as an Intermediate Biklonaut; Shade was seen working on one during season 5, but the results of that were never shown on-screen.

Pio's suit now reads his eyesight and adjusts its visor to match the vision quality of his glasses.
