Ganondorf leans back and forcefully kicks with his left leg. It has good start-up, has great knockback, and is a semi-spike, making it an excellent edge-guarding move against characters with little horizontal recovery options, such as Little Mac. It is one of the only tools Ganondorf has for spacing, even though it is not a great spacing move. It can also be used to punish opponents who charge in recklessly or be a safer read option against characters with no projectiles to aid their approach. If some characters fail to tech Ganondorf's Flame Choke, they can be forward tilted as a followup option, though Ganondorf's down tilt is generally better as a combo starter.
The move is based on a kick Ganondorf and other large enemies use in The Legend of Zelda: Twilight Princess.
