When the Sun and Moon fought relentlessly, causing Dream Land's day and night to cycle rapidly, he appeared before Kirby and suggested that making a wish to the wish-granting machine star, Galactic Nova, could stop the fight. However, at the end of the journey, just as Kirby was about to make a wish to Galactic Nova, Marx shoved him aside and wished to 'make Popstar his own,' causing Galactic Nova to charge toward Popstar. Marx laughed gleefully and revealed his true form with wings spread. While the Sun and Moon realized the situation and blocked Galactic Nova, Kirby flew into Galactic Nova's interior on a Starship, deactivated it, and chased Marx for the final boss battle. After the battle, he begged Kirby for forgiveness and became his friend. He lives at Magolor's house. He cried a lot when he was young.
