The Whizzer appeared in the second season of the Marvel Cinematic Universe television series Jessica Jones, portrayed by Jay Klaitz.

[2] The second, villainous version appears in the final panel of The Avengers #69 (Oct. 1969), the first chapter of a three-issue storyline by writer Roy Thomas and penciller Sal Buscema.

[11] The Squadron are mind-controlled by the entities the Over-Mind and Null the Living Darkness, but are freed by the Defenders and aid the heroes in defeating the villains.

[14] Gruenwald, Ryan, and inker Al Williamson created a graphic-novel sequel[15] which maroons the team in the mainstream Marvel universe.

Also named Stanley Stewart, the character is a young African-American man who develops super-speed as a result of exposure to an alien retrovirus.

[26] In the team's first mission, Whizzer and the Squadron Supreme of America fought Namor and the Defenders of the Deep, when they targeted a Roxxon oil platform off the coast of Alaska.

[28] During the War of the Realms storyline, Stanley was working at his desk until he and the other members of the Squadron Supreme of America were summoned to Washington D.C., where Phil Coulson brought them up to speed with Malekith the Accursed's invasion.
