On a tiny star, two elderly Hammer Bros. are grandparents to a beautiful girl, Princess Peach. However, she is so beautiful, that the evil demon king Bowser decides to kidnap her and make her his wife. Ojiisan attempts to reason with Bowser offering him anything he wants but Bowser simply laughs and kidnaps Peach leaving the elderly Hammer Bros. sad and lonely. Peach rejects Bowser's marriage proposal however, so Bowser holds Peach prisoner in a cave until she agrees to marry him. The grandparents have no hope for Peach to return and are no longer able to concentrate on anything because they miss her too much and are lonely. Meanwhile, the evil demon king Bowser continues to rob and plunder the galaxy stealing treasures from the many stars and planets with his children. The elderly Hammer Bros. look up to the sky wishing for Peach to be returned to them. That's when a giant Peach falls from the sky and splits into halves. It reveals a baby-boy in the inside. Seeing this as a gift from God, the elderly Hammer Bros. couple decide to raise the boy named Mario as their own child. Many years passed and Mario grew to be a brave and strong boy making the elderly couple proud. However, the couple still miss Princess Peach but decide that it's best not to talk about her knowing they can't rescue her. Mario however wishes to know who Princess Peach is so the elderly Hammer Bros. reluctantly tell Mario who she is and how she was abducted by the evil demon king. Mario, after hearing the story, decides to set off to free Peach from the demon king's claws. His foster-parents attempt to talk him out of this, but Mario insists that he will save Peach, the elderly couple accept his decision and send him off with a container of his favorite food and a gun before wishing him luck on his journey. Mario starts his journey singing a cheerful song, shortly after he begins his journey he meets a Para-Beetle, who crashes into him complaining of hunger. Mario decides to give the starving Para-Beetle his food, who after receiving this kind gesture decides to join Mario on his quest to defeat the evil demon king. Mario and the Para-Beetle continues this journey, but when they come across a Boomerang Bro. who has been flipped up on his shell, Mario helps the Boomerang Bro., who thanks Mario for saving his life and decides to join Mario and the Para-Beetle on their journey. Shortly after this they encounter a Spike, who wishes to join Mario on his quest to get revenge against Bowser for destroying his planet. Mario accepts this offer and the Spike joins the fight against Bowser. The heroes board a ship and begin their travels to face Bowser at his hideout. Bowser who is in the middle of asking Peach to marry him is alerted of the heroes attack by his son Roy, Bowser tells his children to prepare for battle and leaves Peach to confront the heroes. The heroes descend on Bowsers hideout and are confronted by his children who immediately attack, Morton, Roy and Iggy attack the heroes with their magic. But the heroes get the upper hand when Spike throws one of his Spiked Balls at Ludwig which explodes knocking him out. Mario than charges at Bowser who prepares to confront him with a spiked club, as the Para-Beetle takes out Wendy with a hard tackle and the Boomerang Bro. strikes Iggy with his Boomerang knocking him out. Bowser attempts to take out Mario with his club, but Mario dodges his strikes, making the Para-Beetle hit Bowser from behind with a hard tackle followed by the Boomerang Bro. striking Bowser with his Boomerang and ending with Mario striking Bowser in the face, knocking him out.
