Any characters can be used.

For me, hands down, Spikelunestia 100 years into the future. All three of them are pretty much immortal... why not have some fun?

What about you guys?

When I'm in an especially shippy mood? The Elements of Harmony.

CMC FTW!!!!!

You good sir. Win.

Twilunestia?
Mane 6 harem?
The banner of this group?

Lately I've had a weird craving to write RainbowFlarity. Where Rarity and Dash take it on themselves to help Little Mrs. Anxiety Disorder into the world of romance, and end up falling for her themselves.

(Also Twilight/Cadance/Shining Armor, don'thurtme. )

1966399 Flaripie. Hooves down.

1966398 if you want to read a story with Flaridash, lucky you! http://www.fimfiction.net/story/50725/unexpected-confessions

Nothing wrong with a little Twi/Cadance/Shining Armor.

Are... are you me? Like... Down to crossdressing Caramel. Holy butts.

My FAVORITE poly ship is still Pinkie and the Cakes, though. Cutest thing that ever traipsed through my head.

1966385 Best all-mare harem period.
1966391 Plus Babs?
1966398 My pairing has incest brah, you cool.
1966410 Didn't know Derplunestia was a thing. Learn something new everyday huh?

Apparently it's on my read-later list already. Totally forgot about it though. Will have to push it up in priority.

Could have just been very Spike-centric.

But really, AppleDashLight.

For romance, I really like AppleDashLight
for clop as a fling, my vote goes to RariJackDash
I'm also a big fan of the mane six all together.

1966379 or . But, is also growing on me.

While it isn't my main poly-ship, I do kind of like Pinkie x the Cakes.
My main poly-ship would be AppleDashLight, mostly because each of them are pretty much experts as far as their races go (at least, until Twilight grew wings.)

Spike x CMCs

Hmm. How about Iron Will, Diamond Tiara, and Angel Bunny?

... oh wait you said ultimate, not high on crack. I get those confused often.

...and maybe have them with everyone else...

True Polyamory for the win. The symbol is a heart with an infinity symbol overlaid, why waste the infinity you're given?

I'm gonna have to say Shiny Love Sparkle, it's just too adorable.

In other news, Flash Sentry x Twilight Sparkle is best 2-partner ship, purely because the shipping name could (and should) be Flashlight.
