Goombas are common enemies that appear in the Mushroom Kingdom stage of Super Smash Bros. Melee's Adventure Mode. They can also have a chance of come out of Crates, Barrels, Capsules, and Party Balls in VS Mode. Goombas walk back and forth on the arena, and thus often walk off the edge of a stage (if present). Nearly every attack can KO a Goomba in one hit, and jumping on them or throwing them will KO them instantly; If the player makes contact with one in any other way, they will take damage with moderately low knockback. For every Goomba the player KOs, they get 150 points added to their Goomba KO bonus.
In VS Mode, Goombas inflict 8% damage on a player who makes contact with them. In Adventure Mode, the amount of damage it inflicts depends on the difficulty setting.
8-bit Goombas also appear in the background of the Mushroom Kingdom stage. They are however just background stage elements, and have no effect on gameplay.
Goomba also appears in the game as a trophy. The trophy is unlocked by completing Event 14: Trophy Tussle 1, which entails fighting three random characters on top of the trophy.
Goombas are actually traitors who've defected from the Mushroom Kingdom's forces. They're a slow and predictable nuisance, as they always try to wander into Mario's path. Fortunately for Mario, they don't have much stamina, as a single jump on the head is generally enough to defeat them.
Goomba is a special stage that can only be played in Event 14: Trophy Tussle 1
The battle takes place on top of an enlarged Goomba trophy, which can be won upon completing the event. The edges of the head can be grabbed if a character tries to recover.
Goombas make an appearance in Super Smash Bros. Brawl's Subspace Emissary mode as enemies. Unlike their Melee counterparts, Goombas cannot hurt players simply by running into them. Instead, they will now charge the player at a slow running speed.
Goombas are among the least threatening enemies in The Subspace Emissary. They have among the lowest HP, where most attacks, even on Intense difficulty, will KO them in one hit, and a jump on their head will always instantly defeat a Goomba. Their movement speed is slow (though they are slightly faster when they charge), with no ability to jump, and they appear oblivious to the player until approached. Their sole attack is slow on start-up lag, and easy to guard against. Along with being slow, the Goomba's charge attack is weak, dealing low damage and knockback, having low KO potential overall. When a Goomba begins its charge attack however, it will continue for quite a while, and if it goes past the player, it will turn around to then charge again.
 HP and damage taken
It is currently unconfirmed whether Goombas have higher HP on later stages.
 Trophy Description
A citizen of the Mushroom Kingdom who sided with Bowser when he invaded. Goombas slowly chase after Mario on stubby legs. They're not the toughest creatures and can generally be defeated by jumping on them, which makes them disappear. They have fierce fangs, but they don't seem to serve any purpose. Though a nuisance to Mario, they're decent at baseball and mah-jongg.
 Giant Goomba
Giant Goombas (デカクリボー Dekakuribō) can also be found in various stages where Bowser's minions are present.
Their behavior is the same as that of a Goomba, and they share the sole charge attack. Unlike their smaller counterparts, they are much more resilient, being able to sustain multiple blows and jumps on their heads before being defeated. Giant Goombas run faster when charging, and as expected, its charge attack is much more powerful, causing high damage and knockback. Giant Goombas also have some flinch resistance to weaker attacks, which can make it difficult to stop a charging Giant Goomba.
Despite their high HP and power, Giant Goombas are still of relatively low threat. Having the same behavior as Goombas, their AI is rather basic, and Giant Goombas take much longer to begin their charge than Goombas do. When jumped on, Giant Goombas are also stunned for a sizable period of time while taking significant damage. Thus, Giant Goombas can be defeated with relative ease by simply jumping on their heads till they are defeated, which can easily prevent them from being able to begin their charge attack.
 Damage taken
 Giant Goomba Trophy Description
A giant-sized Goomba, as the name suggests. In Super Mario 64, punching and kicking had no effect on this brute. It could be stopped like normal Goombas- by jumping on it from above. A colossal Goomba appeared as the boss of world four in New Super Mario Bros., but that's a Mega Goomba, not a Giant Goomba.
