A Combustion Chakram has four half-circle recessions lining its outer wheel. The other four sections of the wheel each sport a spike, and the handle, which is shaped like a cross, is connected to the wheel by the four recessions. The handle is grey, while the main wheel is red on the outer edge and black on the inner edge.
"Combustion" is the process by which fuel reacts with oxygen, yielding heat and energy.
The ground combo starts with a slide towards the target, then a slash to the left and finishes with Axel jumping in the air and throwing his chakrams upon the target. During this combo, there is the option of using the button to finish the combo early with the jumping throw mentioned before.
