The Legend of Zelda: A Link to the Past/Light World Enemies

Keese
Like the ropes, these are almost exactly the same as their real counterpart animal, the bat. They rest still in the room and wait for you to come near, as you do they begin flying towards you. They can fly over walls and other obstacles, making killing them sometimes annoying as they fly out of your reach. You will mostly find these in caves and underground areas.

Mace Wielding Soldiers
First encountered guarding Princess Zelda's cell, these soldiers are more difficult than the average. They carry powerful balls on chains that they will spin around them until they throw it at you. Because of how they swing their mace around, getting near them to damage them is troublesome. The best way to defeat the first one is to grab a pot from the first cell and hit him with it, doing so twice will kill it. They appear again later in the game in golden armour, though you will have more weapons to aid you in defeating them.

Soldiers
The first enemies Link encounters, these are the Soldiers of Hyrule Castle, turned against you by Agahnim. They believe that you have kidnapped Princess Zelda(which is posted on wanted signs for you throughout Hyrule), and are determined to hunt you down. They come in a variety of different colours and types. Some wield small daggers and wander aimlessly, while others will chase you if they hear or see you. Their strength depends on their colour and weapon, which there are many combinations. Some carry bows and will line you up to shoot you or hide under the swamp grass to pop up and shoot you, while others will toss bombs at you. Attacking these soldiers weapons will only bounce them back a little, you must attack any open area to damage them.

Rats
Simple creatures that crowd underground and empty rooms. Though simple compared to other enemies, their pesky nature can lead to some stacked damage. They're fast and agile, and run around the room changing directions constantly. You'll encounter most in the secret area behind the throne, where it is dark, so it only adds to their agility. They also fill the room in numbers, so be careful navigating the dark areas, and if you're having problems with them, it may help to light the torchs in the room. One hit with your first sword will take them out easy, it's best to just avoid them and slay them as they come. Luckily they can not venture into shallow waters, so use them well to just avoid the hassle of fighting them.

Ropes
Identical to snakes, and are mostly the same. These serpents are quite slow at first, but if you get into their line of sight they will quick dart torwards you. Like rats, they are normally with many others, making it somewhat of a pain to navigate the room with them running around. Ropes will only succumb to two swings of your first sword, hack at them before they get to you.
