Moblins are recurring monsters in The Legend of Zelda series. They are based on the pig-man orcs, popular in Japanese fantasy works; though, depending on the game, they may also have ogre or oni like traits as well. These foul tempered creatures have appeared in almost every Zelda game since the first one and alongside their smaller cousins, the Bokoblins, form the backbone of Ganon's army.
In the first Legend of Zelda video game, they were spear throwing enemies. Their spears could be blocked by Link's shield, and the Moblins could all be easily killed by being attacked by a sword or some other weapon. In this game, there are two different types of Moblins - blue and orange ones, with the former being the mightiest of the two.
In the Nintendo 64 video game The Legend of Zelda: Ocarina of Time, Moblins will appear in the Sacred Forest Meadow (only when Link is an adult, however), where they will charge the hero if they spot him. They're not the brightest creatures in this game, however, seeing that you're easily able to hide in any gaps. Once you near the end of this area, a large, hulking Moblin will not charge you, but will rather smash the ground, thus generating a ripple which will drastically harm Link.In The Legend of Zelda: The Wind Waker, Moblins have a more cartoonish look, fitting in with the cel-shaded direction that the directors were heading toward. They appear early in the game, when Link looses his sword, thus giving him no way to harm them. However, he'll be able to pass by them by hiding in a barrel and slowly moving to the top of the tower. Later on however, he'll easily be able to attack and kill them once he comes in possession of his sword.
Moblins do not appear in the GameCube and Wii video game The Legend of Zelda: Twilight Princess, though initially they were planned to, revealed in pre-release screenshots. As always, the appearance of it was dramatically different from any of the other Moblins in the series, though it was probably influenced by the creatures found in The Wind Waker - as it almost looks like a 3D rendered version of the species found in WW.
Moblins were also featured in the Legend of Zelda animated series.
