Goomba

Goombas, originally known as Little Goombas[1], are one of the major species of the Mario franchise. Since their first game appearance in Super Mario Bros., they have become one of the most iconic members of the Koopa Troop and the entire Mario franchise, appearing in almost every title. Goombas resemble small, brown mushrooms and are a fungus-based species like Toads, Amanitas, Spooks, and Shroobs. Goombas are physically weak and are not much of a threat to Mario or Luigi, since a single stomp usually defeats them, although a number of different Goomba variants have emerged throughout the years; however, they do drop hints of being much stronger and more competent than their appearances suggest, as in the case of Captain Goomba. The Goombas, as a collective race, used to be allied with the Mushroom Kingdom. However, most of the Goombas have turned traitorous and joined the Koopa Troop, an organization led by Bowser. In many games, Goombas are the first enemy the player meets. Goombas have two feet and no visible arms.

However, not all Goombas are allied with Bowser or the Koopa Troop. Some Goombas, such as the inhabitants of Goomba Village, live peacefully inside the borders of the Mushroom Kingdom, while others simply hold no allegiance and operate independently in distant locales such as Monstro Town and Rogueport.

Goombas are usually enemies in these games.

Battle of the Multiverse
Goombas are enemies in this game.

Brutal Mario
Goombas themselves don't appear but instead their cousins, Galoombas.

Super Smash Flash 1
Goombas themselves don't appear but instead Flying Goombas. Flying Goombas are the second most prominent enemies, with Koopa Troopas being the first, to appear in the level Super Mario World. Their attack pattern is the same to all the airborne enemies in SSF, such as Beezlys or Buzzers; it has to make collision with the player in order to damage him. They are very weak enemies as one single attack is enough to get rid of them. A very notable difference between Flying Goombas found in Super Mario World and Flying Goombas found in SSF is that Flying Goombas in SSF will not lose their wings if they are stomped, or more specific, attacked; unlike those in Super Mario World. Also in SSF, Flying Goombas are able to fly freely while in Super Mario World the only thing they did was make small hops.

Mushroom Kingdom Fusion
The Goomba's role in Mushroom Kingdom Fusion is the same as it's always been in past games. All one has to do is stomp on it or have a shell thrown at it and there are no more worries.
