It is up to Flash, along with the assembled Science Police, to use the various powers of Kuuga to stop and defeat the Grongi Tribesmen from their continuous killing and ensure the happiness of others. However, as the endgame draws near, Flash learns that there is a horrible revelation behind Kuuga and the Grongis' leader.

Honestly one of the few good things to happen to me in 2020.

Twilight Sparkle was just your average ordinary girl. She was incredibly smart, had dreams of being an engineer, and had no friends at her school since they all just labeled her as a nerd to be ignored. And she had no aspirations to be anything more than that.

However, during a summer tour of DisCorp, she gets bitten by a genetically modified spider and was given powers beyond her wildest dreams.

But as we all know "With Great Power, There Must Also Come Great Responsibility."

And after a tragedy makes her see this, she realizes that the city of Manehattan needs hope.

It needs a hero.

It needs Spider-Girl.

The First Story In The NEW Equestria Girls Marvel Universe!
-Starts in June BEFORE the first Equestria Girls Movie.

18 years ago, a strange, celestial body crashed just on the outskirts of Canterlot. A mysterious box was found and studied in the Canterlot Research Facility. Despite the time and effort, its secrets have yet to be unearthed....until now.

6 months had passed since the disappearance of Micro Chips' brother, Gizmo. But upon a mysterious delivery, he and his friends Flash and Sandalwood work to crack the mystery surrounding the incident.

Now, rampaging monsters run amok in Canterlot City, emitting a strange gas that turns others into the same creatures. What's worse, Equestrian Magic seems to have no effect. Fortunately, Gizmo had left something behind. A particular system needed to combat these creatures and uncover the truth.

Flash Sentry now takes up the mantle, to build the winning formula.

Now the prison is beginning to weaken, and the King of Shadows has gathered an army of the darkest monsters that dimension has to offer.

Chosen by the Elemental Gems, five teenagers must come together to save the world from the King of Shadows and his Dark Army, as the Power Rangers: Element Fury!

Thank you, SuperSonicHeroes! You are awesome!

Flash would do anything for his friends. And when he sees Twilight in danger, he's ready to do anything in his power to keep her from harm. But things get out of hand, in the worse way possible.

This story takes place during the movie "Equestria Girls: Friendship Games". Alternate universe.

BEFORE READING:

- In this universe, the incident in which Spike gained the ability to talk never occurred. Therefore, he doesn’t speak here. He is, however, more intelligent than an average pet. Basically, the Spike we all know, minus the talking.

- The paragraphs written in all italics are flashbacks, and all of them happened during the duration of the Friendship Games. They occur in inverse chronological order.

- Please go easy on me, I’m not an excellent writer and that I haven’t done this in a while, but I wanted to share this story in written form, because a comic would’ve taken too long.
