What superpower does Elastigirl possess?

Elastigirl possesses superhuman elasticity.

Elastigirl is the superhero identity of Helen Parr, Bob Parr’s wife and the mother of Violet, Dash, and Jack-Jack. Her elasticity allows her to stretch, bend, flatten, and reshape her body into useful forms. She can extend her limbs to extreme lengths, form a parachute, become a flexible boat, or use her body as a slingshot.

Helen first appears as a confident, experienced superhero in The Incredibles. After superheroes are forced into retirement, she adapts to family life, but she returns to action when Bob’s secret activities put him in danger. In Incredibles 2, she becomes the public face of a campaign to restore superheroes’ reputation.

Elasticity is sometimes described as shapeshifting, but Helen’s signature ability is specifically stretching and reshaping her body like rubber. She is not the family’s flyer or invisible member: Violet creates force fields and turns invisible, while Dash has super speed. Helen’s tactical judgment and piloting skills also make her a formidable hero.
