Overview
Kirby jumps with his grabbed target very high in the air and comes back down very fast, similar to Ninja Kirby's Air Drop in Kirby Super Star, causing a small explosion when he hits the ground. The opponent is launched up in the air when Kirby hits the ground. This move became Kirby's up-throw in later installments. The move has very high base knockback, and reasonable knockback growth. It is capable of KOing Donkey Kong on the top platform at 149% and KOing Jigglypuff at 72%.
