Buried
Buried is a state in Super Smash Bros. Melee and Super Smash Bros. Brawl that characters enter when hit by an attack that induces the bury status, including Headbutt, Earthquake from Togepi, or a Pitfall. In this state, controls are disabled until it wears off (this point being where the once buried character will get some invincibility frames). While buried, the character can not be grabbed. Like other status effects, button mashing reduces its duration.
The amount of time a character remains buried is dependent on that character's damage percentage; the higher the meter, the longer he/she will be stuck to the ground.
Characters can only be buried if already standing on the ground; moves that bury will usually meteor smash airborne opponents. Burying someone is a great way to set up a smash attack or other powerful move.
In Melee, buried characters cannot be "unburied" by getting hit; they will remain stuck in the ground until the effect wears off. However, in Brawl, a character that takes a hard enough hit will be relieved of the bury effect and sent flying.
