After their most previous adventure in Egypt, the Mane 6 decide to take Allura and Twitch to visit Spike and the rest of the dragons on the Isle of Scaly, as well as warn the dragons that Alterro is looking for the legendary alicorn land of Skyros, and could come after the dragons as well. The dragons (except for Spike and a few others) are reluctant to prove that Allura’s changed, after all the things that the Mane 6 have said about her, but Allura and Twitch may get the chance to prove themselves as they are summoned on the Mane 6’s next Unity Quest adventure.

Upon arriving within the bustling city of Los Angeles, where humans and anthropomorphic animals co-exist, our heroes soon uncover who they are supposed to help-- a group of notorious villains known as the Bad Guys-- Mr. Wolf, Mr. Shark, Mr. Snake, Mr. Piranha and Ms. Tarantula, who are also the mentors to five Mythix Tiger cub cousins-- Reva, Carmine, Gretchen, Zari and Oran, all while under the watchful eye of a mysterious dragon named Safira, who has fire imbued with dark magic.

But then… one day, the Bad Guys and their young apprentices are finally caught in the act. To avoid a prison sentence, the animal outlaws must pull off their most challenging con yet: becoming model citizens. Under the tutelage of their mentor, Professor Marmalade, and with the help of the Mane 6, Allura and Twitch, the dubious gang sets out to fool the world that they're turning good.

Will the Bad Guys fool everyone, including our Equestrian heroes, or will the feeling of good cause them to really change their ways?  And what are Safira's true motives for the Mythix Tiger apprentices?

Based on the best-selling Scholastic book series, and packed full of heart, action, laughs and the true meaning of goodness and friendship, G5 Adventures in The Bad Guys proves that being bad has never been more fun.
