Phantom Zant

The Phantom Zants are two doppelgangers of Zant paralleling Ganondorf's own Phantom Ganon. They resemble Zant, but transparent, and with a cyan television static-like pattern of them.

The Legend of Zelda: Twilight Princess
In The Legend of Zelda: Twilight Princess, one Phantom Zant each is fought as a miniboss at the end of the west and east wings of the Palace of Twilight, where they guard the sols along with Zant's Hands. They first summon the same type of fence that appears in Twilit Messenger battles, and similar bars appear over the door. Their sole move is to teleport around the arena rapidly and confusingly, occasionally stopping to summon a giant red "egg" of evil energy, which is thrown to create a crowd of one type of enemy. If all of these enemies are not defeated before they throw the next one, the remaining enemies disappear. Each Phantom Zant is only vulnerable to approach as they are preparing to throw the egg, though Link can get a hit in occasionally if they happen to teleport close. When the first one appears, it summons a swarm of Twilit Keese, and as the battle goes on, it may summon more of them, a swarm of Twilit Vermin, or more rarely a group of seeds that grow into Serpent-type Twilit Babas. The second one summons Twilit Babas at first and later can even summon a crowd of Twilit Messengers. Other than that and being more hyperactive with its teleporting, it acts the same as the first one. Each Phantom Zant explodes into a large cloud of dark fog upon defeat.

Hyrule Warriors
In Hyrule Warriors, both Phantom Zants appear alongside Zant during one of his strong attacks, where they throw down a huge ball of energy between them. His Twilight Map costume is also based on them.
