The 'New Captain America' meme refers to the reveal of John Walker as Steve Rogers' successor in the Disney+ series 'The Falcon and the Winter Soldier.' Fans immediately reacted to the character's smug expression and the awkward fit of the iconic cowl, sparking a wave of 'Not My Cap' comparisons. The meme is primarily used to represent a significant downgrade, an unwanted replacement, or a bootleg version of a beloved original. It captured the internet's collective skepticism toward the new character and has since become a staple for comparing superior originals with their less-impressive successors.
