Can you recommend some good Mario and Sonic fanfiction?

Sure. One great Mario Sonic fan fiction is 'The Great Race'. It has an exciting plot where Mario and Sonic compete in a multi - dimensional race. The story is full of action and also has some really cool character interactions.

I've also heard of a fanfic called 'Mario and Sonic: Olympic Friendship'. In this one, the story is set during an Olympic - style event. It shows how their competitive spirits can also lead to a great friendship. The fanfic has a lot of humorous moments, like when Mario tries to keep up with Sonic's speed in a running event, and Sonic struggles with Mario's power - ups.

Sure. One great piece of fan fiction could be where Mario and Sonic team up to save both of their worlds from a new, powerful villain created by the combination of their respective enemies. In this story, they might have to learn each other's unique abilities to overcome challenges.

There could be a fanfiction where Mario and Sonic compete in a watch - based race. The watches in this story give them special powers like super speed or the ability to jump higher. It would be an exciting story filled with action and friendly rivalry between the two iconic characters.

In addition to the main characters, characters like Knuckles and Toad could play important roles. Knuckles could be the muscle, protecting the group from physical threats. Toad could be the guide, showing Sonic around the Mushroom Kingdom. And of course, Dr. Eggman and Bowser should be there as the main antagonists. Their combined evil plans would be what Sonic and Mario have to overcome.

One popular Mario crossover fanfiction is 'Mario Meets Sonic'. It combines the two iconic gaming worlds in an exciting adventure. The characters' interactions are really interesting, like Mario and Sonic racing each other in a mixed - up Mushroom Kingdom and Green Hill Zone setting.

One popular female Mario fanfiction could be 'The Adventures of Princess Peach in a New Realm'. It might explore Peach's character in a different way, like her taking on challenges without Mario's immediate help. Another could be 'Mario's Sister's Tale' which gives an interesting backstory to a fictional sister character in the Mario universe.

There's also 'Peach's Rescue Mission'. In this fanfiction, Peach takes the lead to rescue Mario when he gets captured. It gives a new perspective on their dynamic, showing Peach as a strong and capable character.

Some fanfiction might focus on the relationship between Mario and Vivian. For example, a story could be about how they first met and how their friendship gradually developed. It might include details like Mario helping Vivian when she was in trouble in the Darklands, and from there, their bond growing stronger as they face more adventures together.

There is a fanfiction called 'A Day in the Life of Toadette'. It gives a detailed look at Toadette's experiences in the Mario world. Also, 'The Secret of the Female Races in Mario' explores the backstories and roles of the female characters in a very interesting way.
