The Aerondriver was created by Ryder Marks in 2072 in order to go back in time and defeat Demolon before he takes over the world. Unlike Marks' previous inventions, it uses only the pure power of humans. Two humans with a similar genetic makeup are required to transform into Kamen Rider Beyonder. As a result, the user sent into the past needs to find a close relative.
Time Travel[]
After equipping the Aerondriver, pressing its right-hand side will send the user's consciousness to a set moment in the past. As a result, the user is unable to physically interact with anything in the past while their body remains behind. The user's consciousness is equipped with a manifestation of the Aerondriver while the physical one remains on their body. The time travel function can also be used to send the consciousnesses of other people into the future to the point in time that the user came from. This can only be done for a few hours, and those sent into the future cannot return until the user and their relative transform into the completed Kamen Rider Beyonder. In addition, Kamen Rider Beyonder is able to send both the consciousnesses and bodies of other people to another location in the present.
Transformation[]
If their relative is unwilling to cooperate, the user's consciousness can press both sides of their Aerondriver in order to transform using their relative's body. However, doing so results in an uncontrollable and unstable form known as Beyonder Rage. Once the user and their relative are in agreement, the latter is equipped with another manifestation of the Aerondriver. The two then transform into Kamen Rider Beyonder by pressing both sides of their Drivers twice. Transforming causing the original Aerondriver to travel back in time along with the user's body and any consciousnesses sent into the future. The Aerondriver and the user's body unite with Beyonder while the consciousnesses are reunited with their bodies at Beyonder's current location.
Finisher[]
Beyonder initiates a finisher by pressing both sides of the Aerondriver while transformed. At this point, pressing the right-hand side activates the Rider Punch while pressing the left-hand side activates the Rider Kick. Pressing both sides again instead activates the Beyonder Crash.
Beyonder jumps into the air before covering their right fist in blue energy and creating a Dest Cyclone next to their arm. The Rider then performs a punch while falling, with both the Dest Cyclone and their fist striking the target's shield. The Dest Cyclone spins like a saw in the process until it shatters the shield. Century finally punches the enemy directly, launching them away.
Beyonder jumps into the air and creates a Dest Cyclone from each hand. The Rider then uses the Dest Cyclones together to deliver a downward slash to the opponent while, additionally creating a red and cyan energy slash in the process.
