Tails.EXE is the corrupted version of Miles Tails Prower from the Sonic.exe creepypasta and fan game universe, where the cheerful sidekick is turned into a demonic antagonist. The jumpscare scream became widely shared through Sonic.exe gameplay videos, horror compilations and meme edits on YouTube and TikTok, where creators reuse the moment Tails appears to shock an audience. It remains popular because it mixes nostalgia for classic Sonic with horror, making the scare instantly recognisable even to viewers who have never played the fan games.
