A powerful sorceress threatens town. That's the least of everyone's problems.

Tom and Boulder finally come together.

Sablewing the Wicked, a black-hearted dragon with an immunity to magic, invades Canterlot with his army of diamond dogs, goblins, and kobolds. As they attempt to defend their kingdom, Princess Celestia and Princess Luna are captured and imprisoned by the foul reptile, and he proceeds to take over the entire city. A rescue attempt made by Princess Cadence and Twilight Sparkle is then performed, and immediately thwarted, resulting in their capture as well.

Having used the Elements of Harmony to save the Tree of Harmony recently, and being one pony short of using them anyhow, Twilight Sparkle's friends find themselves in the worst predicament imaginable. After raiding the library in the Castle of the Two Sisters in search of an answer to their problem, they happen upon, and then proceed to use a spell that shoots out into the multiverse in search of brave, suitable heroes to combat this monster.

Answering the call, four strange characters come forth: The Green Knight, Orange Knight, Red Knight, and Blue Knight; each powerful warriors in their own separate rights, who have honed their expertise in the field of beating the ever-living crap out of anything that has the sheer balls to simply be standing in their way.

Having been bored out of their minds in their home dimension (and being threatened that they would never return should they decide not to help), the four knights jump to the challenge to RIP AND TEAR and rescue some more princesses. They set off, weapons and sandwiches in hand, to kick some monster butt, crash some castles, and take names as violently as physically possible!

...Oh, and a certain mailmare with strabismus joins along on the mad adventure.

"Hey, uh, Rick, what did you want me to, uh, write down here again?"

"Look, Morty, it's not that urp complicated, just, just write down a generic description of what we did."

"But Rick, we did a lot of things!"

"Then figurp it out, Morty. Christ, and here I thought you were getting at least a bit smarter. Just, write down something about, uh, 'Rick and Morty Get Stuff From Horse Land'. 'Morty and Rick and something something horse pun'. I dunno, something."

"I want to go back to the ponies..."

"Oh, I bet you would like that, huh, MMMorty? Go back to the girly dimension full of urp friendship and magic and all that. Look, just give it here, I'll, uh, just put it up as it is."

Now with coverart by some guy named Shadow Bolt

A timeless foe threatens the land of Equestria, neigh the world and beyond, and only Princess Twilight Sparkle is able to prevent this crisis. She will most certainly embark on a legendary quest that will undoubtedly span many written volumes and be filled, filled to the brim with rock hard drama, life-changing decisions that may jeopardize friendships and even a few cheap laughs along the way. Or not.

"Thanks, Mom." Two simple words said by a simple guard.

Not so simple when those words are accidentally addressed to Princess Celestia.

In search for a replacement for his pet Daisy (his rabbit). Doomguy finds himself in Equestria right after Twilight enchanted Smarty Pants with the Want it Need it spell. Now what could possibly go wrong with a Blood Thirsty marine who just defeated the minions of Hell more than once?

You may experience some naughty words!

don't worry the ponies don't swear.

Twilight Sparkle gets hurt. The natural response is to let slip a bad word. But as she lets out said word of bad, something interrupts her. This is surprising, but not unexpected. Random happenings occur in Ponyville all the time. But then it happens again. And again. Pretty soon Twilight Sparkle suspects that there's some larger force at play. It's time to science the fyay! out of this!

What's it been? 1000 years?
That's funny. It feels like much longer than that.

Let me tell you, being trapped in stone that long can do crazy things to a guy.
And when you were a little off your rocker in the first place...
But now I'm free. The leaders of this disgusting place trapped me here, and now they're going to pay.
I'm going to show them the real definition of insanity.

On Earth, air is a hard thing to avoid. So when the PER use it to spread a ponification gas, do humans have any hope?
