No one can deny an old fashioned superhero team-up, especially when that team-up involves another helping of the Power Ponies!

Taking place after the second My Little Pony movie, Rainbow Rocks, and the new Disney film, Big Hero 6, we find Twilight testing out a new spell, a way to travel to other dimensions. It works, only for one of Spike's comic books to get in the way, causing an upset in the spell's process, leading the portal to suck in Spike, his comics, and the Mane 6, sending them to an unknown destination.

They awaken, only to find themselves as the Power Ponies once more, and in an unusual city by the name of San Fransokyo. To make matters worse, the mishap with the spell, fused with the comics, unleashed the Mane-iac, more powerful than she ever was, and even backed up by her own private army of dopplegangers! Now, the Power Ponies must team up with the super hero team of that world, or risk darkness falling upon the city forever.

This thrilling three-chapter crossover adventure brings two times the hero, featuring the return of the Power Ponies! Let the adventure begin!
