Knockback resistance

Knockback resistance is a move property in the  series and in Super Smash Flash 2 where a character is fully or partially immune to knockback. The character will still take damage, though. Grabboxes, present in grabs and command grabs, ignore all variations of knockback resistance.

Knockback resistance is split in three categories; super armor, where a character will not take any type of knockback, heavy armor, where a character is immune to knockback from moves that deal a damage below a specific amount, and launch resistance, where a character's knockback is reduced by a certain amount, and will not flinch if the result reaches zero. There are no knockback resistance mechanics in Super Smash Flash.
