I am trying to create a superhero character that can transform from his normal human form into his Brick form (e.g. Colossus). I am trying to figure the best way to represent this change with either OIAID or Multiform.
I did find the thread at http://www.herogames.com/forums/showthread.php/75482-6E-Mess, but decided to start a new thread as that one appeared to have drifted off topic.
It appears that there are actually three options
a. Just write up the character at both power levels and allow for an instant change. On the downside, the GM should not be allowed to take advantage of the character out of his heroic form frequently as a disadvantage.
b. Write up the character as multiform, with his normal form being the true form and his superhero form being an alternate. Using his brick form as the true form would just result in a loss of points to build what amounts to a disadvantageous alternate form. This would require a half phase transform, and complicates the application of experience points.
c. Have the character's brick capabilities bought with the OIAID limitation. This would require a full phase to transform and / or other means to prevent the transformation. For a brick character this would result in massive points savings as much of his strength, brick powers (e.g. Thunder Clap), defenses, movement powers are all bought with a -1/4 reduction. The increase of a full phase delay to a 1/2 phase delay for multiform is really not that major. The only question remains as to what other requirements over the full phase delay the GM would require.
Based upon the above options, I am leaning towards OIAID option with a full phase to change, a reluctance to compromise secret ID and possibly requiring concentration to enact the change or other requirement.
I am seeking opinions as to the best way to do this while accurately reflecting the relative lack of effectiveness in normal form (compared to supers), without losing points or gaining additional points in a cheesy manner. I am willing to accept the difficulties of tranforming as a dramatic story element.
