The X-Men meme universe is dominated by the iconic image of Wolverine from the 1992 animated series, specifically the episode 'Captive Hearts,' where he piningly touches a photo of Jean Grey and Cyclops. This frame has become the universal symbol for nostalgia, longing, or missing something dearly. Other popular variations include Magneto's 'I prefer the real...' dialogue and Professor X's various reactions. These memes leverage the dramatic flair of the classic Marvel show to highlight feelings of desire, disappointment, or the search for the 'true' version of a concept, making it a staple in internet subculture.
