ReDeads are zombie-like enemies from The Legend of Zelda series. They emit a high-pitched scream and freeze Link in his tracks. While he is frozen they grab hold of Link, and drain his health. A highly similar enemy, called a Gibdo, has appeared in many Zelda games, including Ocarina of Time and Majora's Mask.
Ocarina of Time
ReDeads make their debut appearance in Ocarina of Time. Their appearance is very similar to that of a zombie. When Link approaches a ReDead, it "screeches" at him, immobilizing him temporarily, giving them a chance to jump on his back and start grappling him. This takes a ton of hearts away if Link doesn't escape fast enough. If this happens, and Link does get jumped on, the best way to get off is to mash buttons to try and remove it. They take a lot of hits to kill.
ReDeads also appear in Hyrule Castle Town after Ganon conquered the kingdom, suggesting that they were once villagers who couldn't escape the town when Ganon took over. Weirdly, their screams do not paralyze Link, unlike the other ReDeads in the game.
ReDeads appear once again in the sequel to Ocarina of Time, Majora's Mask, and they attack the same way. However, they only attack Link in his Hylian or Zora forms. The reason for this is since Zora Link is so much like Adult Link, from Ocarina of Time, the animation for ReDead attacks was already done. Because the animation for an attack on Deku or Goron Link was not completed, the ReDeads would still screech, but they would not attack either of these two forms.
There are several ways Link can kill a ReDead. He can stun them with Deku Nuts or spin into them while wearing the Deku Mask, preventing them from attacking him. A Goron Pound is quite effective against them, as well as Zora Link's magic power. An even simpler way, however, is to just shine light on them using the Mirror Shield, which kills them instantly.
If Link wears either the Captain's Hat, the Garo's Mask, or the Gibdo Mask, they start to dance around, in which case they donot attack him, no matter how much he attacks them. They usually drop quite a significant amount of Rupees when defeated, so Link can use this to his advantage to stock up. Interestingly enough, if Link shoots a Gibdo with a fire arrow, they are revealed to just be ReDeads wrapped in cloth.
The Wind Waker
ReDeads in The Wind Waker are pretty much exactly like their Ocarina of Time counterparts. They attack by screaming, which immobilizes Link momentarily, giving them the perfect opportunity to jump on his back, dealing tons of damage in the process. Link can kill them fairly easily, however, as just a few sword slashes do them in. If he shoots them with the Bow, Boomerang or Hookshot, they just creepily stare at him. Link can actually stun a ReDead with the Mirror Shield, if there is a light in the room. This does make them significantly easier to defeat.
- Main article: ReDead Knight
The ReDeads in Twilight Princess are known as ReDead Knights and have many significant differences than that of standard ReDeads. They are much larger than ReDeads in any other games, as well as much creepier. Rather than attacking by jumping on Link's back, this variety screams at him, then hits him with a huge sword, dealing lots of damage in one shot.
