Wario attacks Koopa by running very fast and can easily hit him. He also attacks by going inside his control room which he uses a cannon to throw fireballs.
How to Defeat
In this battle, Wario will run very fast around the whole room and can hit Koopa if he runs past him. Koopa can attack Wario only when he is running by jumping on him at the right time. After running, Wario will go inside a control room at the right side and shoot out fireballs which harm Koopa, but can also be dodged. Wario will go out of the control room and run around the whole room again. Wario will do this routine repeatedly until he is defeated. Every time Koopa inflicts damage, Wario's speed will increase. After jumping on Wario a few times he will be defeated.
