Rabbid Kong's only damaging move is creating a shock wave on the battlefield that deducts 10 HP from each heroic character, and the move also knocks them back unless they have full cover. To damage him, one of the characters must approach him, which will cause the pressure plate in front of him to drop his banana hoard and go ballistic as a result, making him an easier target - however, he will also hit the nearest character with a much stronger attack. When his HP is depleted, Rabbid Kong will move to another portion of the battlefield and replenish himself with a fresh banana hoard, repeating the process. He is defeated after the third phase.
When defeated, Rabbid Kong attempts to make his last stand by standing atop a wobbly block tower; however, Rabbid Peach humorously knocks it over, causing Rabbid Kong to plummet down to his defeat, after being in a selfie with Rabbid Peach.
