Categories are groups of characters that share a common trait, such as 'Pure Saiyans', 'Realm of Gods', or 'Majin Buu Saga'. Leader Skills are the most important aspect of team building, as they provide massive stat boosts (HP, ATK, DEF) to characters belonging to specific categories or types. For example, a character might have a Leader Skill that boosts 'Pure Saiyans' Category allies by 170% HP, ATK, and DEF. Building a team where all or most characters fall under the Leader Skill's boost is crucial for maximizing your team's power. Always prioritize a strong Leader Skill that benefits your chosen units when forming a team.
