Tails, full name Miles Prower, has been Sonic the Hedgehog's loyal two-tailed sidekick since his debut in Sonic the Hedgehog 2 in the early 1990s, and he has since appeared in dozens of games, cartoons and films. His high voice and nervous, earnest personality made his panicked reactions easy to lift from gameplay and animation and share as short reaction clips online. Gaming creators, meme editors and Sonic fans reuse these screams to signal sudden danger, embarrassment or comic failure, keeping the character's familiar panic alive long after the original scenes faded from memory.
