Great Moblin

Link's Awakening
The Great Moblin from Link's Awakening is the "boss" of a gang of moblins that kidnapped Madam Meowmeow's pet "dog". He attacked Link once he reached to final room of the Moblin Hideout where he was holding Bow-Wow hostage. He attacked by dashing forward trying to ram Link but if Link moves at the last moment he'll slam into the back wall and stun himself instead. It is then Link needs to attack his back, and repeat the process until the Great Moblin is defeated. This all takes place before the second dungeon, Bottle Grotto.

Ocarina of Time
A Great Moblin' is the final obstacle standing between Link and the Forest Temple in Ocarina of Time. The Great Moblin easily surpasses the height of his Sacred Forest Meadow counterparts, and with that he also boasts new techniques in an effort to kill Link, and protect the sacred Forest Temple from entry. The Great Moblin wields an enormous club, which creates dangerous shockwaves upon striking the ground.

Strategy
By far the easiest way to kill it is to shoot it with the Bow, or if you do not have it yet, to unleash Bombchus at it. If you have neither, you will have to run at it, dodging the shockwaves it sends at you in the process, and slash it with your sword. It will take some time to recover from this blow, and it may be a good idea to get behind it during this time, because it's fairly immobile, so it won't be able to turn around quickly and face you. If you wish, you can make an easy getaway at this time; however, it will only take another two slashes to take it down, and since you're behind it, it won't be able to retaliate.

Upon death, it will always drop several Rupees, which will either be red, blue, or a combination thereof.

Trivia

 * The Great Moblin's appearance within Ocarina of Time only serves the purpose of halting Link's progression to the Forest Temple. If Link ventures into the Sacred Forest Meadow as a child, however, Moblins will be replaced by mad scrubs, and the Great Moblin will not exist.

Oracle series
The Great Moblin terrorizes the populace in Holodrum and Labrynna. In whichever game the player plays first, Link drives him out of that land. If the player links the two games, he goes into the other land, where Link can further his plot. If the game is not linked, he will not recognize Link in that second land.

In Labrynna he builds a Moblin Keep in the mountain, and prevents the Gorons from growing Bomb Flowers, so he can sell his hand-made bombs.

In Holodrum, he builds another Moblin Keep, as more of a fortress with cannons in the walls, shelling anyone who comes near. His henchmen are greedy as well. Link finds his minions surrounding Dimitri, intending to sell him. To rescue him, Link must pay 80 rupees.

If the player is in Holodrum while playing a linked game, the Great Moblin kidnaps Princess Zelda, hoping to make a profit. After a brief skirmish he flees back to the Moblin Keep.

After Link destroys the Holodrum Moblin Keep, the Great Moblin will move into an abandoned house in the south-eastern corner of Sunken City. There he and his minions make bombs, recuperating their funds to rebuild the Keep once more. If Link drops a bomb or Ember Seed on their pile of bombs and escapes, the house explodes, and the Great Moblin and his henchmen flee. They soon return and rebuild the house (in a much shabbier state), and continue making bombs once more. Link can blow up this second house too, and they will flee again. If Link tries to ignite their pile of bombs a third time, the Great Moblin says,. They throw Link into the house and run away as it explodes, killing Link.
