Adventures of Link Enemies:

Bit:
This is the easiest enemy in the entire game. It is just a small red blob that slowly moves towards you. It appears in the easy enemy action screens at the beginning of the game and will probably be the first enemy that you see. Simply crouch and stab to kill it or downthrust with your sword if you have that skill.

Bot:
This is the tougher version of the Bit. The Bot looks exactly the same as the Bit only it is blue. The tougher thing about the Bot is that it can jump which may cause some trouble. Bots are also found in easier areas near the beginning however they are also in many dungeons and the Spell magic will turn enemies into Bots. Avoid his jumps and kill him the same way as the Bit.

Ache:
This is the Zelda 2 equivalent of the Keese. So with that in mind, it is simply an easy blue bat. It will hide on the tops of ceilings and swoop down on you if you come near it. Avoid it when it swoops but take a sword swing in if you can. The enemies disguised as humans in Saria Town will turn into the Ache if talked to so beware! Most other aches are in caves around Hyrule.

Geldarm:
This is a very long snake like creature that emerges from the sand in deserts. You cannot jump over it because it is so tall so you have to strike it to make it lower into the ground. Once it has shrunk, you can strike it's body again by crouching and a few hits will kill it. The Geldarms are very easy however and they are in a few earlier deserts in the game.

Goriya:
These are one of the earlier "tougher" and "Link sized" monsters you run into during the game. They simply chuck a boomerang at you. The boomerang can fly towards you near your head or legs so you must beware. Just try to use your shield to block off the boomerangs then strike the Goriya like crazy when you reach it. Unfortunately, earlier in the game, you may have to fight many of these that guard areas and are a little tough at an earlier stage in the game. There are also three colors: orange, red, and blue. They get tougher in that order as well. Goriyas are found in many places in the game, especially earlier, so it is hard to pinpoint their exact location really.

Lowder:
These are small beetles that crawl along the ground. They move slow but will race towards Link if they are on the same platform as him. Simply crouch and stab to kill them. They are in caves and deserts, among other places as well.

Molblin:
These are the size of Link and can be kind of tough. The easier kind simply charge at you with spears and sometimes they don't stop coming while the harder kind actually shoot arrows at you. Just don't get hit by spears and block arrows with your shield. Then when you are close, try to strike as much as possible. In order from least tough to most tough would be: orange, red, and then blue Molblins. The Molblins are mostly in the forests but they are in a few other places as well.

Deeler:
These are spider like creatures. There are too kinds of them, red and blue. The red kind hang out in the tree tops and try to fall on you on strings. You can easily get past them and strike them when they are at your level. The blue kind are harder and hop around the area which may be tough. Just try to aim and strike them while avoiding the jumping. Both are in the forests only.

Moby:
These are obnoxious birds that never cease to appear. They will dive-bomb into you so just try to aim for them or ignore them, then get the hell out of that action screen. They are in a few areas such as the harder version of the swamp.

Octorok:
There are too kinds of these, blue and red kinds. The blue ones just sit there and shoot rocks at you which you can block with your shield. The red ones jump and sometimes can walk. Your shield is important when fighting the Octorok. You find these in swamps and caves mostly.

Daira:
These are Link sized crocodile men that wield axes! The orange ones are weaker and simply swing their ax at you while the red ones are tougher and they throw axes at you which cannot be blocked by your shield! These monsters are very tough and should be avoided if possible. If you do confront one, try to jump and swing your sword to maneuver around the deadly axes or just run altogether. The Daira is in some dangerous places such as Death Mountain as well as other tougher areas in the game.

Moa:
These are long flying eyeballs that are supposed to be ghosts. They are very hard as they take a lot of damage away and they are hard to hit not to mention they take many hits to kill. They fly and hover around the screen at high speeds sometimes high above you. Some seem to move when you do so when you try to reach them, they are already gone. The orange ones appear in dungeons and drop fire on you. The blue ones inhabit Old Kasuto Town and are invisible until you have the cross. The red ones are also common in the cemetery and should be avoided as much as possible.

Ironknuckle:
These are tough and common enemies in palaces. They are very heavily armored knights that wield both a shield and sword. Because they have a shield, many times when you try and hit them, they will block it with their shield. Because of this, a good strategy to use is to jump towards them and try to strike their head for it usually gets in a good hit. The orange ones are weaker while the red ones are tough. The blue ones shoot swords at you and they are very hard!

Myu:
This is a very small crawling ball covered in spikes. This is so small that you cannot even kill it when you crouch and strike. Because of this, you need to have the downthrust sword skill to kill the Myu. These creatures are not hard however. They are found mostly in palaces.

Stalfos:
These are skeletons that wield a sword and shield. They are not too hard though as they cannot block below their legs very well so crouching and striking works well. The red ones can jump and do downthrust attacks so watch out. Some Stalfos even have armor on! Stalfos are only in palaces.

Mace Demon:
This is like the hammer brothers in the Mario series. It is a large red demon that chucks many spiked clubs at you. It usually throws a bunch in a row so if you are too close to it, you will not be hit by a club. Wait for the monster to have a pause in throwing clubs, then run in and strike like hell.

Bubbles:
These are not really enemies but they can still hurt you. In a few areas in the overworld, especially on bridges, many bubbles will float up from pits and from below. You cannot kill these bubbles but you have to dodge them.

Rocks:
These are just like the bubbles only they come form the sides and they are in the desert.

Tinsuit:
These are knights with an animal like head that looks like a dog or something. They are in dungeons and charge at you endlessly. They do not hurt you as much when you get hit by them but they do take away experience points. One hit will kill these easy foes as they are probably the easiest enemy in palaces in this game.

Skull:
These are floating skulls shrouded in flames that bounce along the walls. If you get hit by them, they take away experience points. It literally takes scores of hits to kill these creatures!

Ache Demon:
Sometimes there will be a red Ache that you will run into. These Aches turn into a red demon when they hit the ground and the demon shoots fireballs at you. These enemies are tricky so try to avoid them. You cannot quench a fireball with your shield. The Ache Demons are in a few caves in the game.

Megmat:
These are little critters that hop like fleas. They are found in prairies and such and are not that hard. Just aim and strike but don't get hit by them.

Bago-Bago:
These are the skeletal remains of flying fish. They fly up from bridges and spit rocks at you. These enemies are on the bridge action screens. They are annoying but not too tough. Rope:
These are snakes and are the palace version of the Octorok. There are red and blue kinds and the red kind is tougher. These enemies are not too much of a problem.

Dragon Gargoyles:
You may notice dragon gargoyles all over the palaces. Some of these gargoyles shoot fireballs at you but the even tougher kind can fly! The flying gargoyles don't shoot at you but they will fly up and down at fast speeds and may be tough to avoid sometimes. They are not worth killing because more will come and overwhelm you so just ignore them.

Cat Gargoyles:
These also shoot fireballs at you from on the walls. There are flying versions of these too however. The flying cat gargoyles will move up and down slowly and shoot fireballs at you. If you are cornered with many of these then it will be tough to escape!

Doomknocker:
These are very large knights that wield and throw maces at you and they jump as well. Beware, as the maces move like boomerangs do and they cannot be blocked with your shield. The Doomknockers are very tough so you should proceed with caution around them.

Tektite:
These are large hopping spider like creatures in areas like plains and a few other places. They shoot fireballs at you and they are only vulnerable to fireballs so you need the Fire Spell when dealing with them.

Floating Eye:
This is a very slow moving floating eyeball. They will hover around for a few seconds then shut it's eye to rest. It is only vulnerable to kill when it's eye is open. But watch out, for it hurts Link a lot if he gets hit by one. I have seen these monsters in many areas later in the game like forests and caves.

Bee:
These are very fast flying insects that drop rocks on you. They are tough and should be avoided. If you see one, I suggest just running. Fortunately, they are not very common except in a few harder swamps later in the game.

Leever:
These are monsters that appear out of the sand to attack you. Many will always be constantly surfacing and scurrying around towards you but they are not hard to kill at all. Leevers are only found in the deserts of the game.

Basilisk:
This is a rock hard lizard like creature that lives in caves. It will shoot fireballs at you and it's hard defensive shell makes it only vulnerable to fireballs so you need the Fire Spell to defeat it. Scorpion:
This is a giant scorpion that mostly appears in caves. It shoots fireballs from it's tail and you can only kill it when it's eye is open. It is extremely hard and I usually ignore them.

Lizardmen:
These are the toughest overworld enemy and they appear all over the place near the end of the game. They are Link sized Lizard people that wield maces. The orange kind just charge at you while the red kind charge at you while swinging a mace. The blue ones are the ultimate tough enemy and they throw maces at you, which of course cannot be blocked by your shield. There are also some that hide behind a large fence on some action screens and throw stones at you. But those kind are not really defeatible.

Wizzrobe:
These are tall wizards that shoot rays of magic at you. Simply cast the Reflect Spell and then the magic waves will ricochet off of your shield. After this, aim them towards any Wizzrobe and it will hurt them. These enemies are rare and only in palaces.

Wizard:
These are orange cloaked sorcerers that shoot slow moving flames at you. Avoid the flames and strike these wizards before they disappear.

Bird Knights:
These are the toughest enemy in the entire game. They are birds dressed in full armor. Basically, they are just Iron Knuckles that can jump very high and are very fast. You have to maneuver around them very strategically to hit them. Usually it takes all of your energy, health and magic to kill one so I just avoid them. There are red and blue ones but the blue ones are extremely hard. The Bird Knights are only in the Great Palace.

Firebird:
These are very large red winged birds that shoot many fireballs at you. They also hop around a lot and are pretty hard. Just close in on them and then strike them like crazy with your sword. The Firebirds are only in the Great Palace.

Big Skull:
This is a giant version of the smaller floating skulls. The damage this enemy inflicts is a lot more than it's smaller version so beware. There are only a few of these in the Great Palace.

Big Bot:
This is a giant Bot. It hangs on the ceiling and is invisible at first. But when you walk under it, the monster will appear and fall from the sky and try to crush you. One hit will split this large Bot into several smaller Bots. These Bots take a dozen hits to kill and are much harder than the ordinary Bots. There are only about two of these in the entire game and they are only found in the Great Palace.
