Well, for about a year (before I was on this site), I rolled around an idea in my head... an All-OC side story to the show!
Basically, it follows my Mane Four OCs, Titanium Blade, Atom Splitter, Crystal Frost and Scarlet Sands, as they have adventures, like the Mane Six do in the show.
If there is any interest or anyone who has done something similar, please let me know. I want to read it!

Sorry for it being crappy and lacking Cutie Marks, I made it on the fly.
The Ocs are, from left to right: Scarlet Sands, Atom Splitter, Titanium Blade and Crystal Frost.

Titanium Blade

Atom Splitter
