How to Beat Undyne in Neutral route

When the fight begins in the neutral route, the soul will turn green when Undyne will use her spear. In this fight, she will throw arrows from all sides to attack you, and you will have to block them from every direction. The arrows do not have a particular speed, they can be slow and fast. This makes it very difficult to figure out. Do not get hit by multiple arrows at a time because each of them deals five damage.

Ballet Shoes is a great option because you will get three bars when you are attacking. You will just need to focus and attack in the middle to deal high damage. After some time, the red soul phase will begin, and she will again switch back to the green soul, which will make the arrows even faster.

After you deplete her health totally, she will admire your capability. However, she will not give up because of her determination. This will result in her attacks getting slower, and slowly she will fade away like dust.

How to Beat Undyne in Genocide route

In the genocide route, you will face many monsters before you encounter Undyne. After you defeat all the monsters on your way, you will see the monster kid just before facing Undyne. Here you will have two options. The first option is to fight him and then continue the Genocide Route. 

The second option is to spare him and switch to the neutral route. We have already explained to you about the neutral route above. So, if you chose to fight him and attack him, Undyne will quickly come in front and take that hit. She will tell the monster kid to run away as she loves him and she will do everything to protect the dear ones.

In this fight, her name will be Undyne the Undying. Undyne’s attacks will be very fast and will deal 8-12 damage. So, it will be very bad for you if you take a hit from her. The best option here is to stay away and dodge her attacks as much as possible. 

You can use Sea Tea as it increases your speed and will help you to be quick enough to defend and attack the boss. You will also need health items so that you can restore your health whenever it reaches very low. Use the items carefully as you would not like if it goes to waste. Stick to the walls and avoid her arrows in the red soul phase.
