(a sequel to the "Reflections" arc of the MLP comic book series; set shortly after the Season 5 opener): While on the run, the Erroneus Equines (the small-time criminal counterparts to the Mane Six and Spike) end up discovering long-lost magic talismans that grant them near-unlimited power, even to the point of gaining a new "Dark Rainbow Power". The newly super-charged former small time criminals end up going on a rampage that is too much for even the combined might of Captain Goodguy (Discord's Mirrorverse counterpart) and Chrysalis. Fortunately, they ARE able to bring help in the form of the Equestria Prime versions of the Mane Six and Spike. But can even the Mane Six's OWN Rainbow Power allow them to fight their criminal counterparts on equal footing?
