Gravity

Weight is a measurement of how much knockback resistance a character has. In general, this translates to lighter characters taking more knockback and heavier characters taking less knockback than average. Both sides of the scale present their own advantages and disadvantages; heavier characters are generally harder to KO, but lighter characters can escape combos earlier than normal.

However, weight is only one factor that determines a character's knockback. Thus, there exist several characters that do not adhere to the typical behaviors a character of their weight possess. For instance,, despite his low weight, has a high gravity and falling speed, which makes him hard to KO off the top of the screen and increases his vulnerability to juggles. Meanwhile,, one of the heaviest characters in the game, has a very low falling speed, making her very difficult to combo in the traditional manner, but causing her to die off the top from a gentle breeze.

Gravity is a measurement of how fast a character to reach their maximum falling speed. Characters with higher gravity will have lower jumps than characters with less gravity, assuming their jump force is the same. Overall, characters with higher gravity have better approach options due to their faster vertical movement, but suffer from weaker recovery and a higher susceptibility to getting juggled.

Though most fast-falling characters have a higher gravity than average, high gravity alone does not make a character a fast-faller. Rather, it serves to amplify the effects of a character's high falling speed.
