Moldorm (boss)

Moldorms are large versions of Moldorms that debut in The Legend of Zelda: A Link to the Past. Like their smaller counterparts, they move around erratically. They generally try to push Link off platforms to lower floors, and have a weak spot on the end of the tail.

The Legend of Zelda: A Link to the Past
One appears as the boss of the Mountain Tower. Defeating it grants Link the Pendant of Wisdom. One later appears in Ganon's Tower.

The Legend of Zelda: Link's Awakening
A Moldorm is the first boss in The Legend of Zelda: Link's Awakening, and it appears in Tail Cave as the guardian of the Full Moon Cello. It has a different appearance from the Moldorm boss in The Legend of Zelda: A Link to the Past, as shown from its angrier and spikier look. This Moldorm is green, and it has a large pair of mandibles just like those of an insect. However, in the Nintendo Switch remake, it looks like the Moldorm in A Link Between Worlds.

When Link enters the room, the Moldorm buzzes and moves around in random directions. Like the previous game, Link can attack Moldorm by striking its tail with his sword. With each hit, Moldorm moves around faster and more erratically. Link can avoid Moldorm by using the Roc's Feather to jump over it, or by holding out his shield, which deflects Moldorm. There are two pits on both sides, which Link must avoid falling or being pushed into by Moldorm. If this happens, Link falls into in a dark area and must climb out of it from a ladder to return into the main area. Link can return to fight Moldorm, although this restarts the battle. By using the Whirling Blade technique, Link can defeat Moldorm after four hits. When Moldorm is defeated, Link is rewarded with a Heart Container, and he can then enter into the room with the Full Moon Cello.

During the final boss fight against the Shadow Nightmares, one of the forms they take is that of Moldorm, with the Shadow's angry eyes on its tail end.

The Legend of Zelda: Four Swords Adventures
In The Legend of Zelda: Four Swords Adventures, it appears in the Pyramid and is called Big Moldorm. It is gray and its tail end changes color depending on which Link needs to hit it. After each hit, it cycles through the possible colors like a roulette before eventually stopping on another. After four hits, it splits in two. One of the two can be defeated in two hits, while the other takes six. When they are both defeated, the Links are able to free the final maiden. Ordinary Moldorms resemble the boss's appearance from A Link to the Past.

The Legend of Zelda: A Link Between Worlds
It again is the boss of the Tower of Hera, where it is yellow with several lumps on its top and a green fuzz around the rim along its underside. It now has the Pendant of Power, and is fought on the roof. A stronger, purple one with undulating yellow and purple eyes can be found in Lorule Castle. This one is fought at the end of the bomb challenge through the lower left boss fight door, and instead of pits in its arena, it has walls that push closer together, thus shrinking the arena. Both appear in the Treacherous Tower, with the Hyrule version being the final opponent in the intermediate mode and the Lorule version being the final opponent of the advanced mode. Both are surrounded by pits here.

The Legend of Zelda: Tri Force Heroes
It appears as the boss of the Fire Temple with a design uncharacteristically resembling a Trilobyte or a horseshoe crab. Its arena is over a large bit of lava, and lava geysers erupt from three marked circles on the mesh floor. The glow from its large red headlight-like eyes indicate which Link needs to attack it, depending on their color. In single player mode, it also indicates which Link it will attack and will always be the color of the Link being controlled, though if the controlled Link is off the battlefield, the eyes will glow yellow and it will wander aimlessly. As it moves, it slowly unfurls its segments, ending with the weak tail end, the last of which will only appear if it is actively pursuing a Link.. Hitting a Link or switching between Doppels in the arena will cause it to withdraw its segments, thus starting the process over. Its tail end can be hit by throwing the boomerang, luring it away from it while holding the boomerang in place, and then letting it return while Moldorm's tail is between the boomerang and Link. After it takes three hits worth of damage, it will raise its weak tail, necessitating either a totem position or a ranged attack from one of the raised platforms to the side of the battlefield. After three more hits of damage, it will begin moving faster while blinking red.

After three further hits, it will raise its tail again, meaning that either all three Links will need to totem or two will need to totem on one of the side platforms. Additionally, it will start moving more erratically while its eyes flash between all three colors, and it simply runs between edges while repeatedly unfurling its segments, regardless of whether an active Link is on the field or not, and withdrawing them every time it reaches an edge. After one more hit, it is defeated.

Later, one of the Drablands Challenges involves completing the Fire Temple (including the Moldorm fight) with only Bombs as a weapon, including a lack of Swords. In the Fortress, the middle of The Lady's Pets acts as an altered version of Moldorm.

The Legend of Zelda: A Link to the Past comic
It appears as a giant spider.

The Legend of Zelda: A Link to the Past manga

BS Zelda no Densetsu Inishie no Sekiban
In BS Zelda no Densetsu Inishie no Sekiban, Moldorm is the boss of the second dungeon, the Waterfall of Wishing. It looks and acts like it does in A Link to the Past, except falling in the pit resets Link to the boss room's door, making the fight significantly easier than normal as falling does not start the whole fight over.
