Weight

Weight is a measure that determines how much resistance to knockback a character has. It mostly affects horizontal knockback, since falling speed is more important when calculating vertical knockback. Different weights are only truly present in Super Smash Flash 2, due to the flawed physics of Super Smash Flash.

Overview
Weight is a concept that can be described as how difficult it is to send a character flying. Different weights present both advantages and disadvantages to each character. Heavier characters are harder to KO, but most are susceptible to horizontal combos and chain grabs; on the other hand, most lighter characters have the advantage of being less susceptible to combos at higher percents while being easier to KO.

Differences from the main games
Weight in Super Smash Flash 2 does not share all of the effects that are present in the main Super Smash Bros. games: the length of throwing animations isn't dependent on the weight of the opponent being thrown and some standard chain grabs in the main games aren't posible and vice versa. For instance, is susceptible to certain chain grabs, like 's up throw chain grab. However, in Melee, he wasn't vulnerable to it at all, due to his weight.

Types of weight classes

 * Medium-light: Middleground between light and medium characters. Examples include:, and.
 * Medium: They are neither easy nor hard to KO as their weight doesn't present neither clear advantages nor disadvantages. Characters who fit into this category are, and.
 * Medium-heavy: Middleground between medium and heavy characters. They can be easily comboed until medium percents, they're harder to KO then medium weights, but can die earlier then heavies. Notable examples include:, and.
 * Heavy: Hardest to KO and send off stage. Most have a large frame. Examples of these characters are:, and.

Trivia

 * Zero Suit Samus was made a heavy character in the early patches of demo v0.9b, but this was corrected later and turned into a medium-light character.
 * However, Zero Suit Samus is still heaver than she is in the main Super Smash Bros. games. Her current weight is 85, while in the main games it's 81.
 * Kirby is heavier than Pikachu, even though the latter is heavier in all the main Super Smash Bros. games.
