Dark Link
Dark Link is a completely black doppelgänger of Link that appears in multiple Zelda titles, including Zelda II: The Adventure of Link, The Legend of Zelda: Ocarina of Time, and The Legend of Zelda: Four Swords Adventures.
In Super Smash Bros. Melee
In Melee, Dark Link is fought by Link in Event 18: Link's Adventure, but appears nowhere else. Aside from the black texture, he is identical to Link. Since Dark Link is simply Link with a texture swap and the removal of a voice akin to a Metal Box, the texture can be applied to any character with the Debug menu.
In Super Smash Bros. Brawl
Dark Link appears as an alternate costume for Link. This design is based on a cameo appearance of Dark Link in Twilight Princess. Also, Dark Link reprises his role as the target of an event: Dark Link Duel. Strangely, the Dark Link in said event is shown as being completely black, like in Melee. Even stranger is that the Damage meter icon uses the "normal" Dark Link.
