Dialga debuted as the mascot legendary of Pokémon Diamond, released in Japan in 2006 and internationally in 2007 for the Nintendo DS, where it was presented as the Pokémon that rules over time. Its distinctive cry became familiar to players through encounters, battles and later appearances across the main series games, spin-offs and the animated series. As clips from the games circulated online, the cry was reused in fan edits, battle montages and meme videos, and it remains popular because it instantly identifies Dialga and the idea of time itself.
