Would you class something like Tokoyami's Dark Shadow as a Transformation or Mutation type quirk or a combination of both? Because his body is always altered but the quirk isn't always active.

I personally class Dark Shadow as a Transformation quirk himself and Tokoyami is a product of a Mutation quirk but never the less Tokoyami would be classed as having a transformation quirk~
