A new feature is the Kizuna Rush, which summons another character alongside the player in battle to perform a combination attack
Up to four players can be summoned at once this way, with the finishing attacks becoming more powerful as more characters join
During battle, one of the NPC support characters (known as Crew in the game) may become a Hero, which causes the Kizuna Gauge of the support character who is a hero to fill up more easily
Maxing out this support character's Kizuna Level and filling their Kizuna Gauge, will unleash their Hero Power
Some characters like Luffy, Usopp, and Sanji can use a special state called an Overdrive which allow them to use their signature power-up states like Gear Second
