Multiform

[dsatow]

If a multiform character's change doesn't change the person's appearance, does multiform require the advantage invisible power effects?

 

Ex: Channel is a superhero who can channel the spirits of incredible heroes.  He can become a world class cat burglar, a famous detective, an incredible actor, or a kung fu legend by taking in the ghost of one of these people.  Physically, he doesn't change just mentally.

I'd say that's up to each individual GM. I can see good arguments on both sides of the issue, so I think it's safe to leave it to common sense, dramatic sense, and special effects.

 

I will note, though, that the character you describe could easily come up with a "visual" hook for his powers. The Kung Fu Legend would probably move (and perhaps talk) differently from the others, for example, and you could come up with similar perceivable clues for each "identity."
