Dark has twelve spikes facing the clockwise direction. These protrusions are closely packed together with minimal space between each, resulting in an overall round shape. This shape hinders the Metal Wheel in two ways, as its protrusions are not pronounced enough to provide sufficient Smash Attack; while the perimeter is interrupted too frequently for sufficient Stamina. Additionally, its weight is distributed over too large a surface area, resulting in poor defensive capabilities. It is the same fusion wheel as Dark Wolf
This shows the original mold of H145, but it showed breakage problems, so the gaps were reinforced. It can be used in Attack and Defense combos, however it is outclassed in both due to recoil, and also floor scrapes.
SD is one of the best bottoms for stamina, although meant for Balance. It is much better than the D tip. However, it is outclassed by W2D, WD, EWD, and PD due to the low surface area. It is, however, very good on 85, which keeps it stable.
