Units in Gachaverse are used to battle against enemies in the Battle mode. They are arranged by their rarity and a specific element. In-game, a range of 3-star to 6-star is only available with water, fire, wind, light and dark elements. Although it has been revealed that 7-star units will be introduced, together with hero and corrupted elements.

Units' strength is measured by the value of attack and defense points, both of them divided to physical and magical. Just like in the previous games, they possess active and leadership skills, although only a few of them have further explanation of its' capabilities. Units can also be awakened, using a specific amount of awakening material. Such action unlocks more room for leveling up and a different look of the units.

Each unit also has a short storyline, which is accompanied with a short quote from them, so that players can learn a bit about their favorite characters and form a deeper bond with them.
