Stretch is the lanky leader of the Trio with a thick Brooklyn accent. Stretch is the most aggressive at scaring the living by possession, morphing or simply appearing. Although he acts the harshest, he is soon revealed to have a soft spot, and is perhaps the most sensible in making important decisions. In a deleted song he claims to be schizoid-paranoid, and despite his intelligence, he can be very childish at times.

Stretch was voiced by Joe Nipote in Casper and its television series, The Spooktacular New Adventures of Casper, Jim Ward in Casper: A Spirited Beginning and Casper meets Wendy and Sscott McNeil in Casper's Haunted Christmas and then by Dan Castellaneta in Casper's Scare School. However, in the series, he's voiced by Matthew Geczy.
