BB-020 Avalanche Thetan is the twenty-first release in the Micro Disk System. It is a Class-C Top.
Trajectory Cap: ThetanEdit
Thetan resembles an Ape's fist with a subtle "fire" pattern surrounding it. (Trans. Foggy White)
Contact Ring: AvalancheEdit
Avalanche is the first Class-C ring. It has a width unique compared to the others, at least roughly. The perimeter, vertically, is sloped. It has a design faintly similar to Cognitive (Gear Shaped Ring, Essentially) with the exception an implied jagged design throughout the "teeth".
Spinpoint: Shallow BallEdit
Shallow Ball is the Micro Disk System equivalent to the Hybrid Wheel System's Wide Ball. It functions with similar balance and travel attributes. (Trans. Foggy White)
Spinpoint Shaft: Semi-Low ShaftEdit
Semi-Low is the third lowest shaft. Its primary focus is contact ring destabilizing. (Trans. Foggy White)
Body Shell: 3-Metal-Ring ShallowEdit
As the name implies, this is a low-sitting body with three metal rings surround the profiling. Acts much in a similar vein to Spiral Metal Balance. (Clear White)
