Dustin Henderson
Dustin Henderson, played by Gaten Matarazzo, is a 14-year-old adolescent and one of the significant characters from the initial three seasons of Stranger Things. Despite battling cleidocranial dysplasia, which results in a lisp and makes him vulnerable to bullying, Dustin exhibits self-assurance and a goofy character that charms viewers. He is best friends with Mike Wheeler, Lucas Sinclair, Eleven, Will Byers, and Max Mayfield, and his cleverness and love for science and technology often come in handy during their adventures.
