Upon entering the other provinces of Hyrule covered in Twilight, Link is again transformed into his wolf form, and can only regain his human form after aiding the Spirits of Light by restoring light to the area. Link is eventually able to return to his human form with the aid of the Light Spirit Faron. It is later revealed that anyone engulfed in the Twilight will normally be transformed into a helpless spirit, and that only the power of the Triforce protects Link and enables him to retain his physical form, although considerably altered. He is then dragged off by the Shadow Beasts and imprisoned within the Hyrule Castle Sewers, where he meets Midna, who helps him make his escape.

Link falls to his hands and knees and morphs from human to wolf, causing him to pass out from the strain of the transformation. As the Shadow Beast clutches Link around the neck, the mark of the Triforce suddenly appears on the back of his hand and bursts forth pure light, driving the creature back. Suddenly, the massive arm of a Shadow Beast springs from the Twilight, dragging Link inside. When he wakes up, Link runs in pursuit of his kidnapped friends, but finds a Curtain of Twilight blocking his path. Colin and Ilia are carried off, and Link is left lying unconscious in the spring. Link is first transformed into a wolf following the appearance of Bulblins at Ordon Spring. In this form, Midna rides on Link's back giving directions, and allows him to warp using the Portals created across Hyrule. Though losing the ability to use items, this new form grants Link heightened senses and speed, along with many other unique abilities. His whole body changes and reforms, leaving only his earrings, his distinctive blue eyes, and the Triforce mark on his hand.

Link is transformed into this form due to the influence of the Twilight covering Hyrule. In Twilight Princess, Wolf Link is the divine beast that Midna explains the Twili have long believed would free them.
