Garlic

Garlic is portrayed as Wario's favorite food, appearing as a recurring item in the Wario Land and WarioWare series, along with Wario's other appearances in the Mario franchise. It often functions as a beneficial item that heals Wario or gives him strength. Wario is said to eat whole cloves of garlic constantly, making him smelly as a result.

Wario Land series
In Wario Land: Super Mario Land 3, a type of garlic power-up called the Garlic Pot appears. It turns Small Wario into normal Wario, and normal Wario into Bull Wario. It returns in Virtual Boy Wario Land as the garlic bottle.

In Wario Land 3, garlic represents the Super Smash treasure that Wario has to collect. Once found in the Tower of Revival, after Wario opens the blue snake door, it will confer him the ability to break solid blocks. Also in Wario Land 3, several heads of garlic can be seen hanging from some platforms in Forest of Fear; if Wario is transformed into a vampire and touches a garlic head, he instantly reverts to his regular form.

In the pre-release versions of Wario Land 4, the Heart Gauge was shorter and had a garlic icon next to it, implying that Wario originally had to collect garlic rather than little hearts to recover his Heart Meter.

In Wario Land: Shake It!, garlic restores hearts in Wario's life meter. Shaking an enemy will occasionally cause it to drop a head of garlic, which will start bouncing on the ground until collected. Most enemies' garlic only restores one heart, while some enemies (such as the white Bandinero) release a bigger type which restores three hearts.

Wario World
In Wario World, garlic heals Wario, and Garlic Dispensers vend heads of it to him in exchange for coins. They are also sometimes found in wooden chests.

WarioWare: Touched!
In WarioWare: Touched!, Wario eats a "Nasty Garlic" in Wario-Man's intro cutscene and transforms into Wario-Man. After the microgames are beaten for the first time, it will then appear on the main selection screen so that Wario can turn back into Wario-Man at any time.

Wario: Master of Disguise
In Wario: Master of Disguise, garlic is one of the five kinds of falling objects that appear in the minigame Trash It. When garlic appears, it must be dropped into the mouth to score. Garlic also appears as one of the possible images shown during Trick Slider and one of the shapes the blue dot needs to be traced through in Zappy Path.

Mario Kart Arcade GP / Mario Kart Arcade GP 2
In Mario Kart Arcade GP and Mario Kart Arcade GP 2, Garlic is a special item for Wario. The Garlic is a recovery item. Upon being used, it will remove all bad conditions from the user's kart, such as square tires, burst tires, or Thunder Cloud. In addition, the Garlic provides a shield for approximately half a second upon being used. With good timing, this can be used to block incoming items or be immune to the explosion of a Time Bomb. In Mario Kart Arcade GP, a variant of the Garlic known as the Garlic+ can be unlocked. This variant greatly increases the duration of the shield the item provides.

Mario Kart Tour
Despite not reappearing as items, garlic is referenced to in Mario Kart Tour in the course Ninja Hideaway, where icons of garlic are shown on banners.

Super Smash Bros. series
In Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U, Wario eats a head of garlic (called "Nasty Garlic" in the English version) to transform into Wario-Man for his Final Smash.

Mario Party 10
An enormous head of garlic can be seen as an ornament on the Wario Board in Mario Party 10, lying on a table-like platform at the right side of the board.

Mario Tennis Aces
In Mario Tennis Aces, Wario eats a head of garlic to strengthen himself as part of his Special Shot, the Glorious Garlic Bomber.
