The 'It Was Me, Dio!' meme, also known as 'Kono Dio Da!', originates from the 1980s manga series JoJo's Bizarre Adventure and its 2012 anime adaptation. The scene occurs when the villainous Dio Brando forcibly kisses Erina Pendleton, Jonathan Joestar's love interest, and smugly proclaims, 'You thought your first kiss would be JoJo, but it was me, Dio!' This moment became an internet sensation due to Dio's over-the-top expression and the sudden betrayal it represents. It is widely used as a 'bait-and-switch' meme, where the audience expects one outcome but is instead confronted by Dio's unexpected presence, making it a staple of anime internet culture.
