Link appears as a playable character in Mario Kart 8 in the first of the two DLC packs.
Link, a warrior from the Legend of Zelda series, has the overall appearance of... well, a warrior. Even though he just races karts in Mario Kart 8, he still is adorned in his fighter gear. He has brown, leather boots with straps around the tops and ankles. They are lighter in the heel area. He has tan (or very dirty white) pants, and he also has a forest green tunic (it looks manly on him). Link has a dark brown belt with a brass buckle that separates his shirt from his tunic. Another belt is strapped around his shoulder, this one is the same color and attached to the one around his waist. This belt holds his sword sheath, which is also dark brown and edged with a brass tip. Underneath his short-sleeved green shirt is a long-sleeved white shirt, which can also be seen right below his neck. Link is equipped with an arm guard for when shooting a bow and arrow, although he does not usually have one. His black gloves are cut off at the fingers, and his shirt is slightly torn at the collar. Link always has a determined look on his face. His ears are pointed, and his long, flowing, blonde hair falls over his forehead and his ears. Link is too good of a fighter to need a helmet, so instead, he wears a long hat that falls over his shoulders. It matches his shirt in color.
If Link is not busy steering his bike on a track in Mario Kart 8, then he will always be brandishing a heavy, sharp, and especially deadly, legendary blade called the Master Sword. The weapon's blade lengthens slightly near the front of the hilt. The hilt itself is a bluish-purple and is designed sort of like bat wings. The handle is green and purple striped, with a small triangular design on the end. In the center of the sword is a small, yellow gem. In his right hand (so he must be left-handed), he is armed with a shield for protection. It is edged by silver, with three nails on the lower and side corners, and on the top corner, a small design is engraved. Two silver notches jut out, along with four jagged designs in the shield. A red, eagle-like icon can be seen, with the wings, legs, body, and head all being separated but close together. And in the center is the Hyrule symbol from the Legend of Zelda, three yellow triangles known as the Triforce and a gray one forming a big triangle. The rest of the shield is faded blue in coloration. That is one decorated shield.
On July 19, 2018, an update was released to Mario Kart 8 Deluxe where you can play as Link in the champion's Tunic costume from The Legend of Zelda: Breath of the Wild. Along with the addition of the Master Cycle Zero bike, the Ancient Tires, and the Paraglider.
