Elastic Lad is a super-hero alter-ego used by cub reporter Jimmy Olsen. Olsen is traditionally known as the closest friend to Superman, his greatest pal. In this identity, he has the ability to stretch his body parts to incredible lengths. The transformation is caused by Elasti-Formula. He is an honorary member of the Legion of Super-Heroes. The Elastic Lad alias was created by Otto Binder and Curt Swan, first appearing in Superman's Pal, Jimmy Olsen #31.
