Fans spotted a Howard the Duck cameo during the sequence, and there were tons of unexpected MCU characters in the movie, including Robert Redford’s Alexander Pierce, Natalie Portman’s Jane Foster, Harley Keener from Iron Man 3 and Edwin Jarvis from ABC’s cancelled Agent Carter series.
Just about every character showed up for the battle scene, so it’s not tough to imagine that the new leader of the Ravagers came out to assemble for battle.
