Gohma

Gohma is usually depicted as a large insectoid, spider-like creature. She often serves as a boss for Link and is seen in quite a few Zelda games.

In The Legend of Zelda
The Gohma makes her first appearance in the first game. She is underworld boss of the Dragon maze. The easiest way to eliminate the Tektite Queen is to shoot an arrow into it's eye. One hit in the eye will defeat the boss. However, it's eye needs to be open for you to hit it. Gohma will also send fireballs your way to stop you from defeating it. The sixth piece of Triforce is your reward for her defeat.

In Ocarina of Time
Being Ocarina of Time chronologically the first chapter of The Legend of Zelda, Queen Gohma debuts as the first boss enemy Link will encounter in his adventures. After the Great Deku Tree refused to place the Spiritual Stone of Forest into Ganondorf's hands, the Gerudo warlock cursed the ancient tree with a monstrous, Tektite-like creature, Queen Gohma, titled as a Parasitic Armored Arachnid. Ravaging the inner body of the Deku Tree, spreading her offspring, scattering her web, and leeching on the Tree's life, the Great Deku Tree had no choice but to request for Link's help with the aid of Navi the fairy. Queen Gohma was found on the deepest floor inside the Great Deku Tree, resting atop the ceiling. When Link confronted her, he discovered she had one weakness: her eye was vulnerable when it turned red. Even with her armor, her sheer bulk of strength and her Gohma Larvae's intervention, Queen Gohma was defeated. The curse been broken, Gohma's consumed in magic and reduced into ashes. Strategy: Not so hard as you might think, Queen Gohma's only weakness is her eye when it turns red, however anywhere else (even her normal eye) but the red eye will result in an useless attack. She has just two ways of attacking you: one is the very first thing she does when the fight begins, Queen Gohma will climb into the ceiling, and from there lay some eggs into the ground (Just before laying the eggs her eye will turn red). The eggs will turn into Gohma Larvae if you're not fast enough to destroy them before they hatch. The Gohma Larvae, as you might know from previous experience inside the dungeon, attack in only one way: when their eye turns red, they will attack by jumping towards you. The second way is by walking menacingly towards you and hit you with her pincers (Again just before she does this, she will "stand up", scream and turn her eye red). As soon as you enter the room, whip out your slingshot and L/Z-Target her eye. When it turns red, shoot it and she will be stunned for a few moments. This gives you the opportunity to hack away with your Kokiri Sword. If you don't defeat her the first time, L/Z-target her again as soon as she get up, and wait until she's up on the ceiling. She will try to unleash her babies on you; when her eye turns red, unload with your slingshot. However if the babies still come, L/Z-Target them and defeat them quickly. When Queen Gohma comes back down, continue with the same pattern as before until you defeat her and earn your prize: a Heart Container and the Spirtual Stone of Forest, the Kokiri Emerald, which the Great Deku Tree will give to you, before passing away.

In The Wind Waker
In the chapter of The Wind Waker, Gohma was placed by Ganondorf below the resting spot of the Spirit of the Sky, Valoo, high atop of Dragon Roost Island's peak, without the Sky Spirit knowing about it, in order to torment Valoo and thus angering him so that Valoo would become violent and unpredictable, and cause trouble, confusion, and panic among the Rito, the protectors of Din's Pearl. Link offers himself to help the Rito, and when he reaches the boss room inside Dragon Roost Cavern, he finds an impressive, lava-resistant, Magtail-like monster as his foe. Nevertheless its amazing, menacing figure, Link manages to crack open Gohma's armor, and delivering many lethal strikes to its eye with his sword, Link finally kills Gohma. Strategy: The first obstacle to inflict any significant damage is to get rid of Gohma's hard shell. First, use your Grappling Hook on Valoo's tail that is sticking out of the ceiling, do a good swing and let it off where you can land on a safe spot (it's better if you can land in one of the wooden platforms along the stone wall) and watch the ceiling cave in over Gohma. Do this again twice and Gohma's shell will be destroyed, leaving its weak spot, its eye, vulnerable. Use the grappling hook on Gohma's eye to bring it down to your level and attack with your sword to defeat it. Once you achieve this, you'll receive your prize: a Heart Container and an apology as well as Din's Pearl from the Chieftain's son, Komali. You must defeat Gohma twice, once in Dragon Roost Cavern and once in Ganon's Castle to complete the game.

In Oracle of Seasons
Gohma also makes an appearance inside the Dancing Dragon Dungeon while on your adventure through Oracle of Seasons. This time around, though, the beast has an extra appendage, a very deadly claw. Getting rid of the claw is the first order of business, so slash at it with your sword. However, to avoid the claw, you should use the Roc's Feather to jump over it. Once the claw is destroyed, use the Slingshot to fire at it's open eye, while avoiding the larvae it summons. Once it is defeated, the fourth Essence of Nature, the Soothing Rain is yours.

In Twilight Princess
In Twilight Princess a more spiderlike reincarnation of Gohma appears called Armogohma.
