Alright, still working on character ideas. This is what I came up while half asleep this morning around 7 am.
I want to throw around some concepts here because this idea deals with physics and there are probably better people than me here to refine this.
This idea, as it stands now, is intended to be the power concept for my character Summer:
In some as yet unexplained manner her body will sometimes defy the basic laws of physics and probability.
Here are some basic examples of the effects on her power on her.
Newton's First Law essentially says that an object in motion or at rest will remain in that state unless acted upon by an external force. This would be why, in a car wreck, the car suddenly stops and your body goes flying through the windshield.
The shorter the distance moved in a short time the greater the force. So, with the body only moving from its seated position to impacting the dashboard or steering wheel, the force (and subsequent damage to the body) is extreme.
Airbags assist the person by doing two things. Its size distributes the force over a greater area to reduce the impact (just as being hit with the broad side of a board doesn't hurt as much as being hit with the head of a hammer). Also, because the air bag increases the time until impact the force has been greatly reduced.
Alright, so in Summer's case she might be in a car wreck and yet her body remains at rest relative to its starting position. Everything else crashes and she doesn't.
This is actually the origin situation I am considering for her. But there are some factors to be considered, such as what happens when the parts of the car behind her (like the seat she's sitting in) come into her from behind?
If she doesn't remain at rest then she avoiding the forward collision only to get slammed forward anyway by the seat hitting her in the back. ... If she does remain at rest then she is stationary when she gets hit with the seat, which is just as bad.
She could be effectively anchored and invulnerable at this second, like The Blob from X-Men.
Newton's Second Law "The net force on an object is equal to its mass multiplied by its acceleration" could indicate that her body would not experience either the acceleration or impact of the crash from either side if what actually happens is that her mass becomes exponentially and instantly increased. (more then like Harry Leland from the Hellfire Club)
That would seem to open up a whole new set of questions as well. In any event this needs some deep thought.
I want Summer to be able to fly though. So, being able to decrease mass as well as resist the law of Gravity could easily get her airborne.
I don't know how she would propel or maneuver though. But then, how does Superman or any of those dudes fly?
Newton's Third Law states that "Every reaction has an equal and opposite reaction". This may be where her saving grace (and explanation for the above issue) comes into play.
Normally, whatever we exert force on exerts back an equal force. This is why it hurts your hand when you hit someone's jaw or why we get hurt when we fall.
If her body spontaneously defies this Law then she could get hit with the seat in the back and yet not feel anything. In fact, she could have even been flung into the dashboard in the first place and felt no impact.
I would very much like to hear some feedback on the "Law-Breaking" power. I am sure it will require a good deal of examination and testing by hypothetical scenarios.
