The '& Knuckles' meme originates from the 1994 Sega Genesis game 'Sonic & Knuckles,' which featured a unique 'lock-on technology' cartridge that allowed players to combine games together. The specific logo used for the meme comes from the title screen where the '& Knuckles' text appears below the main game title. It surged in internet popularity in the early 2010s as a way to satirize excessive branding, re-releases, and DLC expansions. Users began photoshopping the logo onto movies, other video games, and even household products to create absurd, imaginary expansions. It remains a staple of retro gaming culture, representing the peak of 16-bit era marketing and the internet’s love for redundant, layered additions.
