Frisk Undertale
The protagonist of the game has to go through all the adventures. He has many enemies along the way that he has to fight. He is the last of eight people to enter the dungeon through Mount Ebott. In the walkthrough you have to accompany the character and get out of the location.
Once you have passed all the enemies, you will be able to help and leave this horrible place. He doesn’t have his own defined identity, so it’s up to you during the process to decide what you will be. That’s surprising, isn’t it?
