Dokkan Mode is the ultimate attack any character can perform. You need to meet the two requirements first:
Once activated, you must tap the marker moving in the Z symbol in the screen. The marker will pick up speed as it moves along the symbol. Tapping the markers correctly will make your attack more powerful. A character in Dokkan Mode will unleash a punishing array of combos before finishing off with a powered-up Super Attack. This mode is undeniably flashy but the damage amplification/reduction between Types also plays a vital role in the damage output.
