You will have to move the heart to escape the attack.

Once it still comes to a battle, the main hero will transform into a small heart symbol. As Frisk moves on, lots of other antagonists will appear on the way. In this case, the hero can even make friends with some of the monsters and even find out the reason for their cruel war with people. It is a peaceful route, where the kid learns to solve different puzzles and settle all conflicts without any violence. But the latter character saves Frisk and shows a different way to move on. By the way, he wants to kill the hero himself and steal his soul. The former one suggest you should kill all the enemies you meet on your way and earn experience points. When a player only starts his trip around the underground world, he meets two monsters – Flowey and Toriel. Later in the game we learn the possible name of the hero – Frisk. Moreover, you can even give him a nickname you like. So it is up to you whether to consider it a boy or a girl. What’s interesting is that it has no clearly defined gender.
