Princess Dark Matter Returns
 
The evil herald has returned for round two against Twilight Sparkle and her friends. This time she will make sure that Megan does not get involved. She kidnaps her and traps her inside a magical transparent box, so she can use the Mane 6 as bait. Pinkie, AJ, Fluttershy, Rainbow Dash, and Rarity finds Megan, but it was a trap. Princess Dark Matter was able to retrieve the cutie marks once again. It is up to Twilight Sparkle, and Delta Brony to defeat her, get their cutie marks back, and save Megan.
 
P.S. Starlight Glimmer will help Twilight and Delta fight against Princess Dark Matter
