Problem with Density
I'm trying to create my Power Pack hybrid character and the Density power is giving me some headaches. Here is how the power is suppose to work:
The character can control the density of his molecules. He can either expand them to the point that he becomes an insubstantial cloud, or he can compress them to the point that he is nearly impervious to some damage. However, there are certain aspects to this which require some pointing out.
1) When he compresses, he does not gain a strength bonus. He remains at the same strength.
2) His weight remains the same, as he is not making himself heavier - he is only squishing together what is already there.
3) As an adverse effect to his compression, his size is reduced accordingly.
Thus, the character can shrink to the size of a doll, but his weight would still be the same, and his strength would not change. However, his molecules are so tightly compressed that physical, and maybe some energy attacks, cannot pierce his skin. (Within reason).
Now, Jemal gave me some ideas on how to make this fly in M&M but I'm having problems getting it to work together. The Density power increases weight and strength. So we don't want that. The Insubstantial power at Rank 2 is a perfect match, so there is no problem there. The Shrinking power with the +1 normal strength extra seems to do what I want, but it doesn't allot for the toughness and impervious traits you get with Density.
Now, if there was a way to take Density, add no weight and strength increase as flaws but have it directly proportional to the extent in which he shrinks while taking Insubstantial as an alternate power, then I guess it could work.
But I'm not really sure how Alternate Powers work, or Power Feats.
So, if anyone can re-explain these two things in their own words I'd appreciate it. The book isn't helping me grasp the concept.
Or, if someone can tell me just how to make the power work within the specifications I described above, I'd appreciate it. Any ideas?
