The 'Scar Eats Mufasa' fan theory gained massive traction in early 2021 after a viral video suggested that hyenas don't actually eat lions, but lions are known to cannibalize rivals. The theory centers on a scene from The Lion King where Scar is seen playing with a skull that resembles a lion's anatomy, leading fans to conclude he consumed his brother's remains. This meme template is widely used to express shock at childhood-ruining realizations or to highlight dark plot twists in popular media. It captures the disturbing shift from innocent nostalgia to a grim biological reality, making it a favorite for lore-heavy jokes and cinematic over-analysis.
