The line comes from Sonic Adventure 2, the 2001 Sega game that introduced Shadow the Hedgehog as Sonic's dark rival. Shadow delivers it with the character's trademark cool detachment, and it quickly became one of his most quoted lines among Sonic fans. As clips spread through gaming edits, memes and soundboards, it moved beyond its original cutscene into a shorthand for a dramatic beginning. It endures because it is short, instantly recognisable and perfectly suited to introductions, rivalries and moments that need instant attitude.
