|Artwork for the Wheel Cutter in Mega Man 10|
By default, it lets the user send out up to three bladed wheels that drop down from the buster before traveling forward, gaining speed as they do. The wheels drive off of ledges and can scale up walls, only being stopped when they hit a ceiling. If a wheel is dropped from a height, it will bounce up three tiles (or higher if used underwater) before moving.
When the attack key is held, the user can instead attach a Wheel Cutter to their buster, which will be able to rapidly deal damage at a rate of seven ticks per second without consuming additional energy. Holding a wheel against a wall will allow the user to scale it quickly for as long the wheel is touching it. Releasing the attack key will make the wheel drop down as normal.
