Shadow Link

In an Omake, he's shown to have a blog on his computer, usually just posting stuff out of fun and faking to take pictures outside, as he can't go out in daylight.
he can't handle light because it physically hurts him.
his personality tends to be sarcastic and somewhat playful, in a little cruel way. He's shown to be also manipulative to get what he wants, yet slightly easy to gain his trust.

In this timeline, he is still alive and gets SOMEWHAT along with the other Links.

In the Four Swords manga by Akira Himekawa, Shadow Link was drawn from the Dark Mirror by Ganon to act out his wishes. Shadow Link is a twisted version of Link, born from his own shadow, and is a cruel, malevolent, and calculating character. He first appears after causing the Shrine Maidens to vanish, and proclaims himself to be "the hero, Link". Completely avoiding Link's attack, he immediately kidnaps Zelda and sends Link to the Four Sword Sanctuary, from which he observes as Link awakens Vaati. His next move is to lead Vaati's troops to attack Hyrule Castle and send all the Knights of Hyrule to the Dark World. There, he confronts the four Links, revealing himself to be much stronger than they are with their tainted blades, and striking them down with Sword Beams. They are saved by the Blue Maiden, who releases a Fairy to shine light upon him, stunning him long enough for them to escape.

Shadow Link continues to plot, hidden away from the light. As he cannot go out in daylight, he works with Vaati's minions to thwart the progress of the four Links. Using dark magic, he manages to split the four Links apart by sending them to four different lands of Hyrule, thus weakening the strength of the Four Sword. Then, confronting Vio, he attempts to coerce him into joining the side of darkness by appealing to his intelligence. Working with Vio, he traps Red and Blue in the Temple of Darkness, and allows Vio to be placed in charge of the Tower of Flames on Death Mountain. Vio even appears to kill Green in battle, totally convincing Shadow Link that he has turned to the side of evil.However, Vio is simply putting on a show to gain his trust. Once inside, he learns about Ganon and his potential weakness, and the existence of the Dark Mirror, the source of darkness from which Shadow Link was originally summoned. He also learns that Shadow Link does not desire to follow Ganon, and in fact wishes to rule over Hyrule alongside Vio.

Shadow Link is a young boy with pale skin, blue eyes, and short, ruffled purple hair. He wears a short-sleeved black tunic with a long-sleeved white shirt underneath, white opaque tights, and black boots. A brown belt with a golden buckle in the shape of a spiral secures his tunic at his waist. He wears a long, black cap on his head. He is sometimes drawn with fangs and claws.
He can also take on a form wherein his entire being becomes one black silhouette except for the white silhouette of his eyes.
