Beat Down Boogie finally releases part 5 of Mario Warfare, 4 months after releasing part 4. Princess Peach gets into the Fight Club with the help of Donkey Kong and finds herself facing Mario. Mario refuses to fight a woman as he gets beaten up and half-heartedly fights back until Luigi recognises her as Princess Peach and immediately tells Mario who immediately kneeled and asks for the fight to stop.

The whole Fight Club bow down in respect to the Princess and were convinced to join in her on getting her kingdom back. Meanwhile Bowser finally gets the Red Mushroom serum after his scientists completed their research.
