The Rainbooms were on a field trip to the laboratory in Canterlot City. But then suddenly they became bonded with a race of aliens called the Klyntar they need to learn to work together with them as they help a man named Eddie Brock after he lost everything. But he might regain a new life after they take down the evil weaponized Riot.

Join Fluttershy and her friends as she travels to the past to bring long-extinct species back to the present day and give them a second chance.

Magic continues to leak from Equestria to the human world. Fortunately, Twilight Sparkle's inventions have been able to track the magic-infused objects, and the Rainbooms set out on yet another adventure.
The bad news is the items have been moved to Gotham City. The seven young women will have to dive head-first into the most crime-ridden city in the country, hoping their magic abilities will be enough to protect them, and hoping they can avoid a confrontation with Gotham's resident vigilante, the Batman.
Then again, trouble has a habit of finding them.
