Character creation help, please.

[LotH]

I'd like to create an energy projector type character whose body is pure energy and is held in check by a containment suit that allows him to react to the real world. He would be desolid all the time but the suit would allow him to be hurt and function fairly normally as long as he was in it.

How would I go about defining the desolid? What kind of modifiers would it require besides always on? What kinds of modifiers would I need for the suit to allow him to use the powers while in it but to make him unable to affect the solid world once he was removed from it?

I have several ideas but you folks are much more creative than I am so I'd like to get some ideas if ya'll don't mind. :) Thanks.

Sorry I don't have the time to go into it now but here is a quick link to Sam Bell's writeup of wildfire who does pretty much what you describe though at a higher point cost.

In terms of game mechanics, it might be easiest to do multiform (one form desolid, the other solid in the suit). Use accidental change to go from one to the other when the suit fails.

Out of the suit, Desolidification 0 END peristent Inherent Always On, and not much else.

In the suit, take your usual powers, and depending on the breakability of the suit and your character's reliance, apply a focus limitation.

Alternatively, make it a physical limitation (After taking X BODY, becomes insubstantial and can't affect real world, low frequency, fully impairing).
