When Sarge, Grif, Simmons, Donut, Caboose, Tucker and Church investigate a temporal distortion, they get pulled into another crazy adventure when they are transported to Equestria as ponies! Teaming up with the Mane six, they are forced to protect the land and themselves from O'Malley, as the evil A.I. has 48 hours to complete his task.
Extra info:
This fanfiction does not take place in any specific period during the RvB timeline, but it most resembles the end of season two. The Reds and Blues are still at Blood Gulch, O'Malley is controlling Doc, Lopez still has his body and is still with red team, Tex is not present. Any fan of RvB can tell you that there is no period in the Red vs Blue timeline when all of these things are true at once, making this an alternate universe fiction. As for MLP canon, this takes place after the season four finale.
Just watched seasons 1-5 on netflix (and eagerly awaiting 6-10) so I might check this out.
4704620 You only need to know seasons one and two to understand this fic. Thanks for the quick comment! I hope you enjoy if you do read it!
4704693 I'm well aware of that but the site doesn't exactly work well with my phone...
4704706 probably. I know they've been putting it up there (or at least seasons 10 and 11) so I'll look there.
yes! finally a red vs. blue cross over
Just read this. Lol so funny!
You've captured the personalities of the characters perfectly. There were quite a lot of common spelling and grammar mistakes, but I can look past all that easy. Other people might not tho lol.
4705679 If you would like to help, you could point those mistakes out to me.
4705722 Sure I'll have a go. But I'm using internet on my xbox now which is slow. I'll be back tommoro when I'll be on the computer
4705096 You don't remember My Little Caboose: Blue is Magic? It's in the group stories. So is it's sequel
4707451 ... i should have worded my sentence better what i meant was the first one I've seen my self and i kinda didn't go looking for story's with rvb cross-over
Told ya I'd be back!
K so in the description where it says "MLP cannon," it should be "canon." Cannon is the weapon.
"life's great ponders, aint it?" She replied thoughtfully. - "She" shouldn't have a capital letter. I made this mistake a lot in one o' my stories. It's easy to make cos question marks n' exclamation marks typically act as full stops, but not here cos it's 1 whole sentence. You did this quite a lot with question marks and exclamation marks.
It should be - "life's great ponders, aint it?" she replied thoughtfully.
I swear, when I read this last night, there were more mistakes. You do some editing or something? There's probably some more in there but I hardly noticed lol. And yes, I did read to the end of the second chapter you were wondering. I won't be able to help much more cos I gots my own fic to look out for.
4707945 that's ok. You NEED to give it a read. It's really good, and long. But with short chapters
Fuck yeah man I've not thought about RvB in FiM but, IT'S THE BEST IDEA EVA
4708666 Thank you
Also, no, I haven't been editing it, so I'm not sure what to make of that.
Yay O'Malley
Oh man, this is so funny. I love how the characters interact with each other. Also, I should point out that my cat's name is O'Mally lol
How long is this story gonna last, exactly? It feels like there's gonna be one helluvan adventure ahead.
4723587 My original idea was for it to only be about five or six chapters, but I've been planning it out, and it turns out that the story is going to be a lot longer than I thought. A lot longer.
4723920 Uber long adventure story? I can relate, bro. I've rewritten the entire Halo CE camaign with canon ponies! 43 chapters!
I'm proud of it, and I can't wait to find out what happens next here 
I want everyone following this to know that I am still alive. I just have a lot going on and I can only write a little each day.
I can already tell this is going to be good....
needed more sexual innuendos from Donut near the beginning
im gonna stop reading here. dont get me wrong, its a good story! it just doesnt grip me too much, sorry
O'Malley the alley pony.

Yo, just curious, when's the next chapter coming out? It's been way too long lol.
4864190 I promise I'm working on it! I also have a 'Daily' webcomic I haven't updated in weeks. procrastination and schedule slips are the name of the game.
4872460 Okie dokie lokie
I was afraid it was abandoned or something lol.
You on DA?
4874391 Nope. Smackjeeves.
Oh this was so fun
Keep it up yo. Looking forward to the next one.
I knew a new chapter would come! :D
chapter 3 lol co-boos
chapter 4 lol loving it
4723587 my cat is also named o'mally
5079406 Cool. Our cats must be evil
5079406 My cat's nickname is O' malley. He's only called that because on bad days he's a little demon.
Lol, Doc is one of my favorite characters in RvB. Is he going to get O' malley out of his head somehow? And preferably not anytime soon?
SHIT JUST GOT REAL!
MOAAAAAAAAAAAAAAAAAARRRRRRRRRRR!!!!!!!!!!!!!!!!!!!!!!!!!!
Is this dead too?

If I saw this comment a few weeks ago, I would have said yes. But that's not the answer any more! I know it's been waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay too long since my last update, but I've decided to finally add to this story again! :D

Has anyone realized that, just now, a blue was talking to a red?
Is Simmons a cyborg at this point? I forgot...
Another story for the graveyard.
