Rope

Ropes are poisonous snakes and enemies that appear in many The Legend of Zelda games, starting with the titular The Legend of Zelda. Ropes usually slither around slowly, but if they notice Link, they charge at him. They can be defeated by a slash from the sword. Their color often varies between their appearances.

The Legend of Zelda
In The Legend of Zelda, Ropes only appear in labyrinths, and will charge at Link if he is on the same x- or y-axis as one with nothing blocking them from doing so. Additionally, they only have sideways-facing sprites. There are two types of Ropes: an orange type and a flashing type. The orange ones appear in the Moon and Demon labyrinths in the original quest, being one of the primary enemies of the former and only appearing in a single room of the latter. The flashing ones only appear in the Second Quest, in Level-3 and Level-8. The flashing Ropes can be defeated if hit four times.

The Legend of Zelda: A Link to the Past
In The Legend of Zelda: A Link to the Past, Ropes, also known as Cobras, are colored gray and move slower than in the first game. Link first encounters Ropes early during his adventure, in the secret passage of Hyrule Castle. The game introduces a variant of Rope called Masked Snake, which has a skull on its head.

The Legend of Zelda: Link's Awakening
In The Legend of Zelda: Link's Awakening, Ropes, known here as Snake Ropes, appear in Turtle Rock and retain their behavior from The Legend of Zelda: A Link to the Past. In The Legend of Zelda: Link's Awakening DX, they are colored blue.

The Legend of Zelda: Oracle of Seasons/Ages
In The Legend of Zelda: Oracle of Seasons and The Legend of Zelda: Oracle of Ages, Ropes, known again as Snake Ropes, retain their appearance from The Legend of Zelda: Link's Awakening but are recolored to green. They now appear from the ground occasionally when Link uses the Shovel.

The Legend of Zelda: Four Swords
In The Legend of Zelda: Four Swords, Ropes, known here as Roopes, retain their green look from the Oracle games, but with more aggressive expressions. They appear in the Chambers of Insight, Talus Cave, and Vaati's Palace. In The Legend of Zelda: Four Swords Anniversary Edition, they also appear in the Realm of Memories in the The Legend of Zelda and A Link to the Past-based stages, as well as in the Hero's Trial.

The Legend of Zelda: Four Swords Adventures
In The Legend of Zelda: Four Swords Adventures, Ropes appear in red, but otherwise look like a more-detailed version of their A Link to the Past design. They first appear in the Eastern Temple, later appearing in the Temple of Darkness, pyramid, and Frozen Hyrule.

The Legend of Zelda: The Minish Cap
In The Legend of Zelda: The Minish Cap, Ropes have the same sprite as in The Legend of Zelda: Four Swords. They appear in subterranean areas and the overworld, most often in Castor Wilds. Like most enemies, there is a figurine of Rope.

The Legend of Zelda: Phantom Hourglass
In The Legend of Zelda: Phantom Hourglass, Ropes are purple, but otherwise look like fairly realistic snakes. Depending on player choice, they can be first encountered as normal enemies on Bannan Island or as a group miniboss and as enemies in the Temple of Wind. Later, they appear on the Ghost Ship, where they hide under steel drums in the cargo hold. On Dee Ess Island, nests with three or six Ropes can be dug up with the shovel.

The Legend of Zelda: A Link Between Worlds
In The Legend of Zelda: A Link Between Worlds, Ropes appear in the same capacity as in A Link to the Past. They now assume a different pose while charging, with their mouths open and heads flailing around. They first appear in the secret passage to the Sanctuary, but can be encountered before in certain caves if the player chooses to explore.

The Legend of Zelda: Tri Force Heroes
In The Legend of Zelda: Tri Force Heroes, Ropes look and act like they do in A Link Between Worlds and are found in Palace Noir.

Zelda's Adventure
In Zelda's Adventure, a single Rope (generically referred to as a snake) appears west of Great Wimbich, slithering about aimlessly. Playing the Flute obtained from one of the townspeople causes it to catch fire and drop the Pyros spell.

Cadence of Hyrule: Crypt of the NecroDancer featuring The Legend of Zelda
In Cadence of Hyrule: Crypt of the NecroDancer featuring The Legend of Zelda, Ropes appear as one of the new enemies in the future Hyrule available as DLC in the digital release but included in the base game in the physical release. They appear in dark green, purple, red, and dull green, with each having a differing amount of health. Normally, they move cardinally slowly to the beat of the music, but upon being lined up to the player character, will begin moving multiple tiles per beat to charge at them.
