With the Storm King possessing the Red Ranger’s father, the heroes need a plan. That may be the least of their worries as they stumble upon a fallen star, leading to one of the greatest cosmic mysteries of all time: The Andalusian Constellation! However, not everything is what it seems, as the constellation also points to a clue of Discord’s past. The stars were actually the spirit of Chaos’s former lover, Cosmos!

Vowing never to bring his companion back, Discord, the ponies, and Power Rangers have to saddle up! But, things take a horrifying turn when they have to face...Twilight?! And the princesses?! This causes Rainbow Dash to be shaken as her friend (whom she was supposed to gather memories from) has gone from good to bad! And with Equestria’s most powerful ponies under Cosmos’ control, the Power Rangers, Discord and the remaining Elements of Harmony are at the mercy of their most galactic villain yet, as they are forced to fight their friends!

If that wasn’t bad enough, Cozy Glow is having a lack of self-doubt about her place on the good side, and isn’t sure if she sees it as a privilege or if she’s of any help to her friends. And, with their friends fighting against the evil galactic fusion villain, and Discord forced to choose a side, the alicorn filly must step up, and become a true hero by trusting her instincts...leading her to face her biggest challenge yet! Are the Power Rangers and Elements of Harmony truly done for good? Or has the time come for a new ranger to turn the tide?

Continuity:
Beast Morphers - Takes place after the heroes find out the truth regarding Mayor Daniels and The Storm King, and before “The Evox Snare” rewrite.
My Little Pony: Friendship Is Magic - A rewrite of the comic arc, “Cosmos” and the second act of the season 10 episode, “Deep Tissue Memories,” so most of this will probably not be canon.

This is the second story in the Rainbow Dash X Red Ranger arc.

Also, in this story, the Black Puma suit (with recoloured Beast-X mode Red Ranger armor) from Super Sentai’s Dobustu Sentai Gobusters will be adapted in the Power Rangers world. Who will be the new black ranger? You’ll just have to wait and see.

I don't own anything. MLP & Power Rangers are both owned by Hasbro.
