Yeah and Pinkie Sense would probably protect them from ambushes, but high caliber explosive rounds and Imperial toughness can nake you overcome alien scorpions size of semi trucks. The most notable of of Catachan Devils took down a banelord, the second most powerful class of the so called “god-machine” mechas by himself. Yeah, those darn IDW toonforce shenanigans make mane 6 kind of OP lame.
 
-Warhammer fanboy

mane six stats with the idw comics  
twilight sparkle solar ftl speeds and system level attack power and many haxes  
rainbow dash ftl speeds and country level strengh  
pinkie pie faster than rainbow dash and country level  
applejaack can keep up with rainbow dash and has country level strength  
rarity country level  
fluttershy multi-city block level  
the mane 6 has been to hell and back and fought demi gods and vilains like discord and nightmare moon,so what can those space marines win

The only reason Catachan hasn’t been claimed by an Astartes chapter is so the Imperial Guard can have something over the Space Marines

@Astronomus  
Wrong.  
Catachan.  
Let’s see.  
These guys are born on a world where everything is tryna kill you.  
75% of all Catachan children don’t make it to adulthood.  
What you have left are the toughest bastards the IG has to offer other than the Death Korps of Krieg.

Send in Sly Marbo

yeeeah, the only thing that would stop the catachans would be magic. and that is only if they dont kill you quickly. this battle would rely on twi and rarity for damage and the others as support. RD would be very useful with speed, AJ maybe for a trench or trap, but that is about the extent of it. If they were against alicorns? Different story.

Gunnery Sgt. Harker crushed a Nid in his pecs. He could crush the entirety of the Mane 6 in them.

Facing the Catachans on their own world?
 
Holy fuck, not even with Twi’s psyker abilities would they stand half a chance.

@That one guy….  
“If you wax your chest and liberally apply oil, it acts similarly to Space Marine armour. Only Catachan veterans know why this works. “

This wouldn’t even be a fight….It would be a massacre. It take them SECONDS to wipe out the mane 6. Seriously, their pecks count as Flak armor.

One Catachan could destroy Equestria a thousand times over

@Background Pony #A54B  
Don’t You mean Colonel “Im stronger than Kharn” Straken (covers in fear[like this will help])

Considering that on Catachan EVERYTHING is trying to kill you from the moment you are beaten out of your mother’s womb, I doubt the everfree forest would have anything that would hinder them very much. After all, compared to the Catachan Devil, a manticore is just an overgrown pussy.
 
Actually I would like to see how Fluttershy would do on Catachan and what would happen if she tried to hug a Catachan barking toad.
 
As for who would win, it all really comes down to whether the Catachans have Colonel “My shirtless pecs are my 3+ armor” Straken or Sly Marbo on their team.

@Overmind  
There is that…  
“PURGE THE XENOS FILTH”  
“Hey!”  
“Sorry Twilight…”

@Rx925  
if you befriend the catachen you can.

I’m pretty sure that you cant friendship away a Chatachan Fang to the neck.

Sly Marbo

Mane 6 win due to ingenuity and Ultra Harmony Laser.

both
 
friendship prevails over all.
