Knuckles the Echidna is a long-running character from the Sonic the Hedgehog games, known for his serious attitude and his rivalry and friendship with Sonic. Short lines from Sonic characters have become a staple of meme and reaction soundboards because they are instantly recognisable even without any visual context. This oh no reaction fits that pattern, giving creators a quick way to signal disappointment or surprise in gaming clips, edits, and short-form videos. Its brevity is part of its appeal, since it can be dropped into almost any moment without slowing the edit down.
