This story is a sequel to Lustering Steel

Following the defeat of Evox, Earth and Equestria are safe once more with new Morph-X towers being built, and the rangers are developing new ranger tech. Also, with Rarity expecting Twilight's arrival for her new dress, Starlight and Spike decide to make a magical scrapbook to surprise Twilight at her coronation. However, all may not be well yet. Steel has found some clues that an old foe the Mane Six had defeated a long time ago may have returned, and the rangers and their friends are skeptical about all this. But, when a disturbance happens nearby, the rangers, Starlight, Spike and Rarity will have to get back together to take on a threat that is old news to Equestria, but new to the rangers! This could lead to a new battle that no one had ever expected, as the heroes not only cross paths with this villain, but Rarity and her friends reminisce about their past moments of generosity.

Continuity:
Beast Morphers - Takes place during the season 2 opener, "Believe It Or Not."
My Little Pony: Friendship Is Magic - A rewrite of the season 10 opener, "A-Dressing Memories," so most of this will probably not be canon.

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