Panel from 'Wolf and Raven', which I thought would work as a full piece. And it does!
Typically, if Raven manages to 'take charge' and fully possess Shade's body, the only outward sign is that his left eye becomes black to match the right, and his voice sounds all wrong... but sometimes if Raven is particularly pumped he can manifest as a visible form. Whilst he still has no corporeal substance, contact with this apparition will drain life force (which adds to Raven's power) and can be lethal if prolonged.
