This page of our guide has information on how to avoid fights in Dragon Ball Z: Kakarot. Remember, however, that fighting is one of the main mechanics of the game, and is the main source of experience points. If you avoid fights constantly, you may have problems with defeating opponents encountered in the later story missions.
If you don't want to face the enemy encountered in the open world, just fly away.
But remember that running away won't give you experience points or other profits.
Markings on the map
A marker appears when you approach an enemy while traveling on the map.
Enemies who don't plan to attack you are marked in blue. This means that you are safe until you are the one who initiated a fight.
If an enemy decides to attack you, the marker will turn red.
