It's not required to a subpower, but can be, and all the density manipulator can't become intangible.

While I'm agree that the power section need a fresh-up, I don't think assimilation are required in that case. They are possibly related in some cases but I don't think this is always true. For example, Speed of the Young Avengers: "Intangibility: He also can use molecular destabilization to walk through solid objects." It is the speed who grant him the intangibility.

But we can list as subcategories to both superhuman speed and density manipulation the Intangibility, with a little text in the message box to explain that the power of the category can lead to that kind of power etc.
