Spin Dash

Summary
Spin dashing is the ability to curl into a ball for multiple applications. This can entail taking the form of a concussive ball or a cutting disk for offensive and defensive purposes. Some users can combine this ability with Vector Manipulation, Instinctive Reactions, and/or Homing Attack to supplement their mobility and ensure their assault isn't dodged.
