Elastigirl is the nom de guerre of Helen Parr, the mom/protagonist in the animated Disney/Pixar film "The Incredibles." This heroine's superpower is her elastic and hyper-supple body; she can stretch and mold any part of her form. She's married to Mr. Incredible and mother to Violet, Dash, and Jack-Jack, a family of crime-fighting superheroes. Here's a lady who will go to any length to serve justice, so reach out and select Elastigirl posters.
