Down smash/Knockback chart
These are charts showing the post hit data (base knockback, knockback scaling, and KO percentages) of the strongest hitbox in every down smash (or in the case of multi-hit smashes, the values of the final hit when all hits connect) for every character in the Super Smash Bros. series. The down smashes are given a general rank in power in comparison to other down smashes based on the knockback produced by their strongest hitbox at critical percentage.
The following chart shows the power of the strongest hitbox of every character's down smash in Super Smash Bros. Brawl (or in the case of multi-hitting down smashes, the power of the attack if all hitboxes connect). For Olimar, the down smash of each Pikmin is presented separately on the chart. For the Ice Climbers, Popo and Nana have their down smashes represented on the chart separately (though due to testing difficulties, when both land their down smash is not on the chart). In the case of Lucario, he is represented on the chart at minimum power, half power, and maximum power (however the chart does not take the stock modifier into account).
The data on the chart was collected from testing on Mario, with the approximate KO percentages based from the center of Final Destination. The down smashes are ranked by which KO the earliest when the opponent doesn't DI.
