Super Mario RPG: Legend of the Seven Stars

One day, Mario sets out once again to rescue Princess Peach from Bowser at his castle. During their battle, a giant animate sword named Exor falls from the sky, breaks through the Star Road (a pathway that helps grant people's wishes), and crashes into Bowser's castle, sending Mario, Peach, and Bowser flying in different directions, as well as scattering the seven-star fragments. Mario lands back at his pad and meets up with Toad, who tells him he has to rescue Peach. Mario returns to Bowser's castle, but Exor destroys the bridge, preventing him from entering.

Mario makes his way to the Mushroom Kingdom, where Mario encounters a "tadpole" named Mallow who has set out to retrieve a frog coin taken by the local thief Croco. After Mario helps him retrieve the frog coin, they return to the Mushroom Kingdom to find that it is overrun by the Smithy Gang, followers of the evil robotic blacksmith king named Smithy. Mario and Mallow enter the castle to defeat their lieutenant, Claymorton (known as Mack in the original game), and subsequently find a mysterious Star Piece. Mallow accompanies Mario to Tadpole Pond so they can get advice from the Frog Sage, Mallow's grandfather.

He reveals that Mallow is not really a tadpole, and says Mallow should join Mario on a quest to find the seven Star Pieces as well as Mallow's real parents. The duo travel to Rose Town where they meet a star spirit who has animated and taken control of a wooden doll named Geno. After battling the bow-like creature Bowyer, who is immobilizing residents of Rose Town with his arrows, they retrieve another Star Piece. Geno joins Mario and reveals to him the Star Piece is a part of the shattered Star Road, where he normally resides.

Geno has been tasked with repairing the Star Road and defeating Smithy, so that the world's wishes may again be heard. The trio retrieve the third star piece then head to Booster Tower, the home of the eccentric amusement-venue owner, Booster, where they encounter Bowser, whose minions have all deserted him. Bowser reluctantly asks Mario to help him to reclaim his castle; Mario agrees, allowing Bowser to save face by pretending he is joining the Koopa Troop, and Bowser joins the party. The new team intercepts Princess Peach just before she is forcibly married to Booster, but it turns out that the wedding was not real; Booster, having no idea what a marriage actually is, just thought it was a fun party and abruptly returns home after devouring the cake.

After her rescue, the princess returns home to Mushroom Kingdom only to then decide to join the party while her grandmother takes her place in disguise. After recovering two more star pieces, they search Nimbus Land. A statue maker, Garro, informs them that Valentina has the rulers of Nimbus Land being held captive, and her sidekick Dodo is impersonating the prince so he can make Valentina queen. Garro recognizes Mallow as the true prince, then disguises Mario as a statue to infiltrate the castle.

There they defeat Valentina and Dodo and liberate Mallow’s parents, the King and Queen. After traveling to Barrel Volcano to obtain the sixth Star Piece, Mario's party learns that the final piece must be held by Smithy in Bowser's castle. They battle their way through the assembled enemies to enter the castle, where they discover that Exor is actually a gateway to Smithy's factory, the place where Smithy mass-produces his army. Mario and company cross over, find the heart of the factory, and defeat Smithy, thereby stopping his army creation and causing Exor to disappear.

The collected Star Pieces are used to repair the Star Road, Geno returns to the Star Road, Bowser rebuilds his castle with his newly reformed army, Mallow regains his rightful title as prince of Nimbus Land, and Mario and Princess Peach return to the Mushroom Kingdom to celebrate their victory.
