The Markiplier Metro Man meme features the YouTube star's face expertly photoshopped onto the body of Metro Man, the superhero from the DreamWorks film Megamind. It gained massive popularity in late 2021 as a key component of the 'Snotty Boy Glow Up' trend, typically synced to the phonk track 'Close Eyes' by DVRST. The meme serves as the ultimate final form in a comparison sequence, representing a person or idea that is significantly superior, more sophisticated, or more powerful than its predecessors. Its humor stems from the surreal blending of Markiplier's expressive features with Metro Man's majestic, slow-motion entrance, making it a staple for showcasing dramatic improvements or 'alpha' status in internet culture.
