Mario
From Paper Wiki
Mario serves duals roles as the hero of the Mushroom Kingdom and Nintendo's mascot. Mario was created by Shigeru Miyamoto in 1981, where he first appeared in the video game Donkey Kong in arcades. In this game, he was referred to as Jumpman.
Paper Mario
Mario is invited to Princess Peach's Castle during the events of Paper Mario. However this time Mario is invited to a party at the castle. Mario rushed to the castle. Mario made his way through the bustling party guests and was chatting with Princess Peach in the throne room. However, Bowser broke in to the castle through the window and using the power of the Star Rod, defeats Mario. He then usurped the castle bringing it high in the air and then tossed Mario out of the shattered window. Mario landed in a small jungle located on the outskirts of Goomba Village. Goombas , being a proficient enemy in many of his quests, surprised Mario with their hospitality. Mario gave his many thanks and headed back to Toad Town via Goomba Road.
Mario heard a Star Spirit called Eldstar asking for his help. The Star Spirit requested that he speak to him on Shooting Star Summit, in which he had more strength to speak better. Once there, Mario met many other Star Spirits asking for his help. He learned that Bowser had imprisoned them in special cards and has given them to his strongest minions. Mario then set out a quest in search of the Star Spirits. Mario made many new friends and partners on his long grueling journey and eventually collected all seven Star Spirits. Mario returned to Shooting Star Summit where he gained access to Star Way. Mario acquired a new ability called Star Beam and was transported to Bowser's Castle from the Star Shrine. While Mario and his team were at Bowser's Castle, they saved the many prisoners and fought Bowser at the top of the castle.
Using his dirty tactics, Bowser broke all routes of escape and used his Star Rod to fight. Mario and the team could not defeat Bowser while he was using the Star Rod, so they instead used Star Beam to weaken his power. The reluctant Bowser was unaffected by it and shook the beam's power off. Watching the team's defeat, Peach asked the people of the Mushroom Kingdom to help Mario and his friends fight through their wishes. Twink helped her convey this message of hope through her wish and suddenly Mario woke up from his fainted status. He recovered all his health and learned a new upgraded version of the Star Beam called Peach Beam. Mario and company, fresh and ready to go, faced Bowser to round two. Mario shot the Peach Beam at Bowser, leaving him defenseless and ready for a fair fight. Mario and his friends defeated the evil Bowser and once again saved the Mushroom Kingdom. The castle returned to ground from whence it came from and another party is held there later. The power of wishes is restored and once again and the Mushroom Kingdom was saved by Mario and company.
Paper Mario: The Thousand Year Door
Peach asked Mario to come to a land called Rogueport during the events of Paper Mario: The Thousand-Year Door. She found a treasure map leading to powerful artifacts called Crystal Stars. By the time he gets there, Peach was kidnapped by a group known as the X-Nauts. They needed to use her as a vessel for the Shadow Queen so that the leader of the X-Nauts, Sir Grodus, can use her power to aid him in world domination. Mario met an intelligent Goomba called Professor Frankly. He told Mario the history of Rogueport and revealed the secret of The Thousand-Year Door.
The Shadow Queen once took control of Rogueport, enslaving and killing many of its citizens. To achieve this, she created the Crystal Stars and used them to give her great power. The Four Legendary Heroes used the power of the Crystal Stars against her and she was imprisoned in the Thousand Year Door for a millennium. Mario set out to collect all seven Crystal Stars. Gaining many new partners and finding all Crystal Stars, Mario went through the Thousand Year Door. There he found Sir Grodus standing before the Shadow Queen's room. Mario defeated Sir Grodus, but was then ambushed by Bowser and Kammy Koopa. This gave Grodus time to escape with Peach to the Shadow Queen's room. When Mario got there, Grodus had awakened the Shadow Queen herself, taking control of Peach's body. Mario had to fight her possessed form and using the help of the Rogueport citizens' wishes, Mario prevailed.
