When used, the Brawler charges forward with its knee out, much like Onslaught. If the Brawler connects with an opponent, it will grab the opponent, dealing 3% damage, and true to the move's name, perform a jumping suplex: a leap upwards followed by a plummet headfirst into the ground, dealing 15% damage. However the throw has extremely low knockback growth, not even KOing at percents higher than 300%, making it more practical for racking up damage. Any opponents nearby will take damage during the grab and the slam, and the Brawler gains super armor during the animation, making the move safe in crowds.
If the Brawler approaches a ledge during the attack, then they will automatically stall, but if the move is used near a ledge, this will not happen. In the latter circumstance, the move can be used as a Sacrificial KO, similar to Kirby's throws in Super Smash Bros. Melee, although it will end up KO'ing the Brawler first. If it misses in midair, the Brawler will be rendered Helpless.
The suplex is a well-known move used in wrestling. The most common version is called the vertical suplex, where a wrestler lifts the opponents up, and forces the opponent's back into the mat by falling backwards. There are multiple versions of the move though, such as the fisherman suplex, where a wrestler hooks the opponent's leg behind the opponent's knee with their free hand, and the German suplex, where the wrestler grabs the opponent by their waist and slams them down on the mat or floor shoulders and upper body first. Franchise-wise, the Suplex move in a game was first used by Kirby and the respective helper in Kirby Super Star.
