One of the key elements of Akira Toriyama's work, Shenron and the Crystal Balls, was bound to be on the Cyberconnect2 RPG, Dragon Ball Z Kakarot. The Dragon Balls are scattered all over the world. Unless you're extremely lucky, Bulma's radar is vital to find them. Among the wishes that Shenron can grant you, resurrecting emblematic enemies in epic battles is probably the most useful.
While this wish may seem absurd, it allows any playable character to face the bosses again and opens up new dialogue possibilities depending on the transformation used at that moment. In addition to earning a large number of experience points, Soul Emblems will be unlocked to enhance your Community Board.
Tougher battles unlock against these same enemies, but this time they'll have a red aura. In addition to providing another challenge, the rewards from these battles are far from trivial.
