Karate Chop is a Fighting type move in the Pokemon series, and Pokemon Stadium brought those battles into 3D on the Nintendo 64, first released in Japan in 1999. In the game the move is paired with a short striking sound that signals a direct hit. Clips of that hit later circulated on soundboards detached from gameplay. Like Doge bonk, it is now borrowed for unrelated videos where a single comedic impact needs to land instantly, keeping a brief Nintendo era battle effect in use long after the original match ends.
About this sound
Karate chop attack sound effect from Pokemon Stadium, the sharp hit noise played when the fighting move lands in battle and creators reuse for strikes.
This is the short impact sound heard when a Karate Chop attack connects in Pokemon Stadium. It lands as a quick, sharp smack with a slicing edge, like a hand cutting through air and striking a target in one clean motion. The clip is only about two seconds long, but the hit is immediate and punchy, with no build up before it. That sudden chop makes a normal hit feel faster and more decisive, which is why it works so well dropped over cartoon fights, sudden strikes and exaggerated martial arts moments.
