Hypermobility is a highly versatile and underestimated ability.

Elasticity (Also called Hypermobility) is the biological ability of a DNA Alternate to make their organic matter highly flexible and pliable, allowing them to stretch and bend in ways normally impossible. The Alternate is far more durable to blunt damage, as their flexible physiology can absorb most impacts. The Alternate may be able to outperform the finest gymnasts with no practice, and slip through spaces too small or awkward for humans. 

Though the Alternate's skeletal system retains much of its durability, the pliability may cause some difficulties with direct weight distribution. Most Alternates with this ability are lighter than normal, and tend to be capable of more acrobatic feats than normal.
