Luigi (SSB4)/Down smash
Two sweeping kicks. It's Luigi's fastest smash attack, coming out at frame 6. It has a sweetspot on Luigi's thighs and a sourspot on Luigi's feet. Down smash is used to cover rolls, punish whiffs with a fast move, stage spike recovering opponents and kill (with the second hit). The second hit is stronger than the first. Both hits send up and behind Luigi. Its startup is also allows Luigi to avoid high-hitting moves thanks to him crouching down.
