Fierce Deity Link

is one of the transformations Link turns into in, achieved by wearing the Fierce Deity's Mask. This transforms him into a mysterious and powerful warrior resembling his adult self (and shares same voice). It is one of four MM3D: transformations in the game.

Transformation
MM3D: obtains the MM3D: after he trades the twenty non-transforming NaN Masks to the four NaN Moon Childs inside the NaN Moon Dungeons. The final MM3D: sitting by the MM3D: will give MM3D: the MM3D: after noticing all his other NaN Masks are gone. Wearing this MM3D: enables MM3D: to transform into the Fierce Deity, only during boss battles.

In, MM3D: can also transform into the Fierce Deity inside the two NaN Fishing Holes. If he attempts to leave when in Fierce Deity form, the MM3D: will keep the young hero from doing so, wondering how he got in there in the first place.

Abilities
In the Fierce Deity form, Link gains greater strength and range in his attacks as well as certain new abilities. Because the Fierce Deity wields the MM3D:, a large, two-handed, helix-edged MM3D:, he cannot use a Shield, although this disadvantage is compensated for by the MM3D:'s superior power (same as Great Fairy Sword). Link can also use the MM3D: to release Sword Beams while MM3D: an enemy.

In, Fierce Deity Link appears as a Sticker.

(Himekawa)
In the, Link receives the Fierce Deity's Mask from MM (Himekawa): and becomes Fierce Deity Link during his fight against it. In a flashback of Majora, it is revealed that while as a dragon, a mysterious man bearing a strong resemblance to the Fierce Deity in both appearance and clothing, had visited Majora. The man played music for the dragon, who danced for three days and three nights before dying. The man then carved the Majora's Mask from the creature's hide, hoping to seal its power. It is hinted in the story that the stranger is in fact a god, the first being that is able to overcome the beast of Majora, and that it does so with music that controls the flow of time.

In, Fierce Deity Link appears as part of Young Link's Mask weapon type moveset. During Focus Spirit, Link can temporarily transform into the Fierce Deity to perform powerful attacks before reverting to his normal self. It also includes all other bonuses characteristic to Focus Spirit. This form of Focus Spirit is unusual in that it lasts longer than any other Warrior's. While in Fierce Deity form, Young Link is able to shoot Sword Beams with most of his swings, but generally shares all of his original form's moves. He can also use the HWDE: to convert his Special Attack Gauge into more Magic to refill his Magic Meter, thus extending his time in this form. Young Link's Focus Attack features him slicing the Moon in half, damaging enemies around him.

An alternate costume for HWDE: based on HWDE: appears in the DLC Pack.

Though SSBfWU: does not appear in, one of SSBfWU:'s alternate costumes is based on SSBfWU:.

In, SSBU: appears as a SSBU: with the ability, Sword Attack Up, which raises the attack power of a SSBU: when they are wielding a sword. One of SSBU:'s alternate costumes is based on SSBU:.

Trivia

 * In, the Fierce Deity Armor appears as an Outfit. It doubles the damage of the Sword, allows Link to shoot four Sword Beams, and reduces knockback from enemies.
 * The Fierce Deity form is popularly referred to as " Link" within community. This is based on an incomplete translation of his Japanese name that incorporates the kanji for "fierce" (Ki), which can be read alone as.
 * The Fierce Deity is the representation of the feelings of all people populating the land of Termina. This representation is reinforced by the fact that it was necessary to exchange all the masks obtained thanks to the different interactions, actions and help provided to the characters of the game in order to obtain the Fierce Deity's Mask. Its own mask is said to be equally dangerous as Majora's Mask.
 * Although there is no official height from Nintendo, due to Fierce Deity's very tall height over most other adult characters and has trouble entering buildings (and it is possible to get actually stuck inside), he appears to be over 7 feet tall, likely the same as Ganondorf.

Nomenclature
The term "fierce deity,", is used to refer to several deities in the Shingon Buddhist pantheon, such as Bishamonten or the Myō-ō, who are fierce and wrathful toward the negative forces that work against humanity's enlightenment, but are benevolent and supportive of humanity. They are seen as deities that work to defeat evil, a quality which the Fierce Deity's Mask gives Link greater ability to achieve.
