Molecular Elastic

Elastic mutates possess the ability to stretch, deform, expand, or contract their bodies into any form imaginable.

Traits
These mutates tend to be quite flexible, both physically and mentally. They are "go with the flow" types, and tends to take life as it comes. Physically, they may be rather lanky, and may find that, if they are still new at using their powers, certain body parts will be stretching without their knowledge (for instance, after they wake up in the morning, they may find that they leave their legs in bed, while their top half is "walking" to the breakfast table).
