Kennen is a yordle ninja champion in Riot Games' League of Legends, known for his speed and lightning-themed abilities, and this clip comes from the game's Brazilian Portuguese voice-over. Lines like this are localised for each region, so Brazilian players hear Kennen announce attacks in Portuguese rather than English. Short champion voice lines are widely shared as soundboard clips because they are instantly recognisable to players and work as quick reactions in videos, streams and memes, keeping this Portuguese call to arms in circulation long after its original in-game use.
