Unlike other Drive Forms, Anti Form cannot be purposefully activated. Instead, it will be randomly activated when Sora attempts to enter Valor, Wisdom, Limit or Master form based on a hidden "Anti Point" counter. This counter is increased by 1 every time Valor, Wisdom, Master, or Limit Form is activated, but is reduced by 10 when Final Form is used, and resets to 0 when a new form is acquired. Gameplay-wise, the Anti Form exists as a consequence of over-using the Drive system, and is meant to be "strong but troublesome".
