Marvel: Darkforce Intangibility

Tyrone Johnson (Cloak)
As Cloak, he is usually intangible, though he can solidify through an act of will, or by absorbing enough of Dagger's light to saturate his form, temporarily. On the rare occasions, when he resumes human form, he usually reverts to his old stutter, which vanishes when he becomes Cloak. His link to the Darkforce Dimension has been severed on several occasions, but he seems drawn to the darkness and vice versa, and he always regains his Cloak form eventually.
