The 'Kilometers Morales' meme is a popular wordplay trend that originated as a spin-off of the protagonist's name from the 'Spider-Man: Into the Spider-Verse' franchise. By humorously applying the metric system to 'Miles' Morales, internet users created an 'international' or 'European' version of the character, often accompanied by images of his alternate-universe counterparts. The trend quickly evolved into a broader 'Name Puns' category, featuring variations like 'Inches Morales,' 'Gallons Morales,' or 'Kilograms Morales.' It gained significant traction on platforms like TikTok and Twitter during the release of the 'Across the Spider-Verse' sequel, serving as a versatile template for unit-based humor and absurd character variations.
