Forward smash/Knockback chart

These are charts showing the KO percentages of every forward smash as well as the base knockback and knockback scaling values of the strongest hitbox (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 forward smashes are given a general rank in power in comparison to other forward smashes based on the knockback produced by their strongest hitbox at critical percentage.

Note that in Super Smash Bros. 64, knockback values cannot be obtained, so instead the KO percentage is shown. KO percentages are estimated by the knockback on Mario in the center of Dream Land.

Character	Strongest Hitbox damage	Other Hitbox damage	Strongest Hitbox KO percentage	Other Hitbox KO percentage

Chart (SSBB)

The Uncharged Other Hitboxes section shows the KO percentages of the other hitboxes of the forward smash while uncharged. Note that if a forward smash contains only one hitbox, this section will read NA. Uncharged Strongest Hitbox shows the KO percentage of the strongest hitbox of the forward smash while uncharged. The Fully Charged Other Hitboxes section shows the KO percentages of the other hitboxes of the forward smash while fully charged. The Fully Charged Strongest Hitboxes section shows the KO percentage of the strongest hitbox of the forward smash while fully charged. Uncharged Base Knockback shows the base knockback value for the strongest hitbox of the forward smash while uncharged, and Fully Charged Base Knockback shows this value for when the forward smash is fully charged. Uncharged Knockback Scaling shows the knockback scaling value of the strongest hitbox of the forward smash while uncharged, and Fully Charged Knockback Scaling shows this value for when the forward smash is fully charged.

Note that base knockback is the knockback produce by the hitbox at 0%, while knockback scaling is the knockback increase per percentage for the hitbox.

It should also be noted that if Lucario is behind by two stocks, his forward smash can KO even sooner than King Dedede's, though this chart doesn't factor in the stock modifier. Also note that only the primary hitbox is affected by charging in Zero Suit Samus' forward smash, even the sweetspot is not affected. So the main hitbox is the hitbox used in the strongest hitbox sections. This information is courtesy of Omega Tyrant.

Legend

• General
  • bold = Indicates the killing percentage of the strongest hitbox in the forward smash.
  • / = Indicates a different hitbox of the forward smash.
  • MH = Indicates that the character's forward smash consists of two or more hits. Link's forward smash isn't considered in this category because each of his two slashes have KO power and unless the opponent is at extremely low damage percentages, it's impossible to land both hits consecutively in the same smash.
  • w = sourspot
  • s = sweet spot
  • a = All hits of a multi-hit smash land.
  • u = Indicates forward smash is aimed up. Not listed unless it results in a difference of power.

• Lucario
  • 0% = Lucario's damage at 0%
  • 91% = Lucario's damage at 91%
  • 182% = Lucario's damage at 182%

• Olimar
  • W = White Pikmin
  • Y = Yellow Pikmin
  • B = Blue Pikmin
  • R = Red Pikmin
  • P = Purple Pikmin

• Ice Climbers
  • B = both Climbers land their smash
  • S = only Popo lands his forward smash

• Link
  • 1st = The first slash of Link's forward smash.
  • 2nd = The second slash of Link's forward smash.

• Peach
  • T = Tennis racket
