In Captain America: Brave New World, Anthony Mackie's shield-wielding 'Sam Wilson' faces off against Giancarlo Esposito's 'Seth Voelker' aka 'Sidewinder', the leader of the mercenary black ops snake-themed syndicate, the Serpent Society. The new winged Captain America rescues hostages and retrieves a stolen sample of the newly discovered metal, Adamantium, from the ruthless mercenary group in Oaxaca, Mexico at the start of the movie and then is later ambushed by Sidewinder, who has been hired by the nefarious mastermind, 'Dr. Samuel Sterns' aka 'The Leader' in his quest for revenge against 'U.S. President Thaddeus Ross'.

The MCU version of Sidewinder doesn't appear to possess the teleporting abilities of his Marvel Comics counterpart, relying more on knives, axes and guns.
This screen-used costume was photographed temporarily on display at the El Capitan Theatre along Hollywood Boulevard on February 19, 2025.
