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.

This was a pretty good first chapter. Lots of info was thrown at us right from the start but I think it was handled pretty good. The big fight scene was my favorite part. I’m interested to see where this goes. I want to see what Flash and his friends will do next. Also, looks like Twilight has an interest in the new hero, so I want to see how that turns out. Can’t wait for more.

Good start here. Can’t wIt to see what’s next

Sounds a lot like Halo and those gas bag creatures.

im afraid ur quite a bit off on Halo, i havnt even read the story as i write this, and i already know what it entails...i might still give it a read though, see if it features any Showa Era Riders...oh well, Build Up!

Oh, this looks like it'll be fun! I wonder who are going to be the other Kamen Riders in this story like Cross-Z, Grease, and Rogue? I'm looking forward to reading more of this story!

I'm not sure if you have it planned already, but I think that Sunset Shimmer could take the role of Cross-Z in this fic. Maybe even use alternate forms that Build used only a few times in the original show. Phoenix could easily be one of Sunset's favorites, but I still see her using the Dragon equipment as well as the Magma form.

Sadly, I can't really take much of an interest in this story. The thing is, the original Build was a genius -hell his Final Form was labeled that- and as much as I like Flash Sentry, I can't see him being a MENSA candidate like Sento was. If anything, Flash would fill more of the Ryuga Banjo role than anything else.

9611117 Don't worry, Snow Fire and I have plans for that.

What happened to the cover art?

Edit: I was using mobile when I wrote this comment originally. The cover art wasn't there, but now that I'm using my laptop, the image is present.

I apologize for that. I was a bit indecisive on how I should make the cover image, and took it down to rethink about it. That and Banshee531 and I left it off to leave a little mystery for the story until after the first chapter has been up for a bit. I ended up sticking with the Build image since this is a Build Story.

It's a good start, though I do hope Flash's Hazard level as a plot point later on.

alright I'm intrigued let's see how this plays out

Another great chapter. I can understand why Flash is conflicted, he has the power to help is friend but he also wants to keep the promise to his mother to stay safe. In times like this I remember the old saying “with great power, comes great responsibility”. I think Flash has already made the right choice. Also, his heart to heart with Shining Armor was touching.

This is starting to get interesting. I'm especially interested in who this "Dragon" is.

real talk Cross-Z is one of my favorite riders

Another good chapter and kind of know why and maybe how Flash Hazard level is.
Also, isn't the gorilla bottle a light metallic Brown and Hawk is orange?

Last one I will lose my mind if Night Rouge is who I think it is.

Oh, this is getting more interesting. Shining Armor gets involved, another awesome battle, and we even have the Dragon Fullbottle showing up already. I wonder if that means we'll be seeing this version of "Cross-Z" soon.

We will get to how the Hazard Level is what it is eventually.

And really? I honestly couldn’t tell in the show. I thought it was a different shade of orange.

Maybe, maybe not. That’s all I can say about the matter.

Don’t you worry. The holder of the Dragon Bottle will be revealed soon. Cross Z is my favorite as well. I just hope I can do this character justice.

Also a bit of a suggestion. If you want micro to improve the drone I'd suggest going the route of the rider buddies. Ya know like the memory gadgets, Candroids, disc animals, etc

Well, the Cross Z Dragon has got to come from somewhere, right?


y not go just a little bit crazy? pull out a Buddyroid? (Tokumei Sentai Go-Busters/Power Rangers Beast Morphers)

Yep I have the gorilla bottle the cap of it is a light metallic Brown, and the clear plastic of the bottle is a lighter color, and honestly, I'm confusing myself here because the more I look at it the more I think of the different kinds of brown the bottle is.
