My Little Pony: Sonic Gen. Underground

by Jake Witt
Sonic the Hedgehog is getting fed up with boredom... Until Time Eater returned and drops him and his friends into Equestria. Guess who crashes the party? (Unlock friends, foes, vehicles, and items by request or interest.)

2021 Update. New Sonic writing project.
----------
Sonic has nothing to do, Doctor Eggman is in jail, everything is like yesterday, heck, the canyons he trains at are nothing new! Well, good thing a hole in space-time sweeps Sonic into a new adventure in a pony land!
Unlock friends, foes, vehicles, and items!
See here for characters.
See here for gear.
Meet the Mane Six!
Meet Sonic the Hedgehog... twice! And help him rescued himself!
Meet Sonic's friends and rivals! ... and siblings?!
Discover secret factions Sonic will probably not learn about!
Discover secret groups Amy will find!
And who is the villain behind Time Eater?

Explore Equestria to save it from being erased and colorless with the help of the Elements of Harmony ponies.

Explore Canterlot High as you try to stop three teenage girls from ruling the world with the power of music! Why does that sound familiar?

This story has canon and past canon characters. i.e. Sonic's siblings from Sonic Underground.
All OCs are slightly altered versions of regular characters and are altered for plot convenience... or just because of Shadow.

WARNING: VILLAINS MIGHT NOT BE KID FRIENDLY. THAT IS WHY "TEEN" IS ON THERE.
I am not consistent in these things above.
There's also secret chapters you can access with the code: Shard the Metal Sonic.
