The clip is taken from Final Fantasy X, the role-playing game released in 2001 as part of Square's long-running Final Fantasy series. Like many short pieces of game dialogue, it has been lifted from gameplay and shared on soundboards, where the line works even for people who have never played the game because the meaning is clear from the tone alone. It survives because it is short, reusable, and instantly readable as disbelief, making it a handy shorthand for calling out arrogance in edits, streams, and reaction clips.
About this sound
A short voice line from Final Fantasy X asking who someone thinks he is, used as a sarcastic reaction when a rival acts overconfident or out of place.
The clip is a brief, incredulous voice line from Final Fantasy X, delivered in a questioning, slightly mocking tone that rises on the final word. It lasts only a couple of seconds, so it lands like a quick jab rather than a speech, with the speaker sounding genuinely baffled by someone else's confidence. Played over gameplay, a meme edit, or a reaction video, it instantly frames the person on screen as arrogant, deluded, or trying too hard. The humour comes from its bluntness: it does not explain the joke, it just calls the moment out, leaving viewers to recognise the overconfidence for themselves.
