--Thunder Bolt--

"Why, yes, Rarity, my hair does look perfect as soon as I wake up in the morning.  It doesn't work that way for you?  I am soooo sorry to hear that, dear!"  Mrehehehehehehe!

*Rarity, crammed under the rear fender*  "Heeeellllp meeeeeee!"

OK, I might as well go ahead and put my first (and so far, only) OC here in the crosshairs.  Sunyatay Sutra.  I was looking for a way to create an "invisible pink unicorn." 

I don't like the fact that Twilight KILLED the Pinkie clones.  Too many Parasprites?  Sure they're flying tribbles bugs, but they're cute so instead of quickly exterminating them...let's lure them away so they'll lay waste to someplace else.¹  Too many Pinkie Pies--fully sapient versions of one of her best friends?  *PEWPEWPEWPEWPEW* and lets hope we like the last one best.  They could have done the episode the exact same way, just had Twilight's spell send each Pinkie to a random distant location.  They would have brought laughter and fun to their new homes, and could have been held in reserve as future episode fodder.  Instead, she massacres them and nopony, not even Fluttershy questions it the way they would have if Twilight had proposed doing the exact same thing to a swarm of pestilent insects.  In fact, the main obstacle in the Parasprite episode was that she couldn't Just Shoot Them.

I could say that it contributes to the show's Creepy Vibe--all those little things that tell us Equestria isn't quite the bright, shining happy-place utopia it looks like on the surface³--but it's still a major inconsistency, IMO.  Especially since the clones get killed for being hilarious.  And the disturbing, very grimdark way they inflated and exploded.  That looks painful. 

NOTES:

1.  Seriously.  They eat everything in their path.  They can fly.  And they double their population every few seconds.  The inevitable mathematics of exponential growth makes them the most dangerous creatures in all of Equestria.  Worse than Evil!Discord.  Worse than the Changelings.  They're the only creatures we've seen who can actually Destroy. The. World.  But nooo, let's not kill them. 

2. The Iron Will episode.

3.  I'm looking at you, Pinkamena, and you, Fluttershy with the mind control power and hidden angry megalomania² and you, Celestia...etc.

How about Pinkie Pie's flying contraption from the episode with Gilda?  Not exactly Realistic^tm but it's clearly designed for a quadruped.  

"Yo, dawg!  Here I am, rockin' this orange pimp suit...

...aaand taking my little sister's ride 'cause my Scion broke down.

I'ma go apply to be the new "NO" meme face now.

A bad brony is one that makes all of us other bronies look bad, whether it be acting akin to the Spanish Inquisition

NOPONY EXPECTS THE SPANISH INQUISITION!!!!

"Our three weapons are surprise, fear, brightly-colored ponies, and catchy songs!"

...wait, does this make me a bad brony?

FlutterROWRRR!

Edit: Ninja'd!

"Ohai!  I'm your local dragoncatbutterflypony!  My parentage?   Don't ask.  Just don't."

Question: Does magic exist in the HumanVerse we'll be going to, or is it a Realistic^tm  world, or even our Earth (with our history, cultures, etc.)?

I'm going to go ahead and sign up with Sunyatay Sutra.  Here is her human appearance:

If there's no magic in the HumanVerse, then her invisibility/intangibility effects will cease when she's there as a human.  She is 14 13 for this RP.

For some reason I get a big kick out of the part of the song where he's saying pony names, then says, "...and Rari-tayyyyy!"  I wonder how long he spent researching pony names and looking for show clips?

i will control your mind with this magic rune

^Works just as well as a caption for your avatar!

Rarity isn't my favorite pony per se, but for all the reasons Earl Grey explained, she is a terrific character.  A few more to add:

13. The way her voice cracks when she goes into Drama Mode.

14. Hers is the only name in FiM that wouldn't be ridiculous in the real world.  I.e., it's at least as good as "Charity" or "Hope," and carries the connotation of uniqueness and value. 

15. I like the way that she plays to the stereotype of the shallow, vacuous fashion-victim, but when shit gets real, she does too.  She's the absolute icon of surface appearance, but her character is an excellent demonstration of the fallacy of judging someone by their exterior.

16: In "Suited for Success," the climax scene where Rarity is asked by one of the snooty Canterlot ponies who those five unwashed party-crashing ruffians were (something to that effect, lol) is the point in a lot of sitcoms and other stories where the character in Rarity's position caves to peer pressure, betrays their true friends, and then has to learn the folly of it and find a way to return to their friends' good graces.  Rarity subverts that trope, because she already knows the right answer and she has the courage and loyalty to stand with her friends. 

A terrific moment, except for the plot hole: "You don't know who they are?!  I thought everypony did!  Well!  If you had ever been personally invited by Princess Celestia to visit the Great Hall of Canterlot Castle, you would have seen that my friends here are commemorated for the ages in stained-glass--twice--for saving all of Equestria--twice--and the artists also captured the nuances of my mane and tail perfectly in those images, even if I do say so myself."  IOW, the premise, that Rarity admires the Canterlot ponies and wants to ascend to their level is undermined by the fact that she and her Mane 6 friends have at least a dozen levels of fame and glory (not to mention badass) over them.  But still, a great episode, and Rarity is awesome in it. 

Hell yeah I'm a Brony!  From now on, I want everyone to call me Scootaloo.

Name: Waldo the Pony-Shaped Travelocity Gnome

Waldo is a mystery pony who appears in every canon episode, fan-made video, and Pony-related RP.  You can spot him if you look carefully enough.  For example, if you look to the upper left of frame #2,386 of Season 1, Episode 1, just above the second star to the right of Nightmare Moon's mane, you'll see the tip of his right ear.  The Grassy Knoll: he was there.  He was running the wind machine that made the flag wave for the Apollo 11 hoax.  He's in several of the images from the Curiosity probe, but NASA denies everything and says he's just a rock.  He's hiding under the table in Leonardo da Vinci's "The Last Supper," but he can be found by geometric construction if you treat the length of Judas' left foot as equivalent to the height of the U.S. Capitol Building in Egyptian Royal Cubits, then proceed down from the tip of Jesus' nose at the same angle as the Orion Shaft in the Great Pyramid of Giza, treating the starting point as the point where the shaft exits the pyramid.  Measure out the shaft's length in Egyptian Royal Cubits (superimposing a properly-scaled diagram of the Great Pyramid's interior over "The Last Supper"), and the place where the King's Chamber would be is centered on Waldo's forehead.  He was present for Elvis' first televised performance on the Ed Sullivan Show, crouched just in front of him; They made Ed Sullivan's camera crew film Elvis only from the waist up, to hide Waldo's presence from the American people.

Waldo is responsible for replacing Old Derpy with New Derpy, and both of them desperately want to marry him.

Database page: http://mlpforums.com/page/roleplay-characters/_/sunyatay-sutra-r3585
 

Backstory: Sunyatay was born to a large immigrant family in Manehattan. Her parents and siblings were all very driven to "make it" in their new home. Her parents relentlessly drove their foals to be successful, but Sunyatay did not have it in her to be forceful and competitive. She went from being a major disappointment to being...overlooked entirely.

At school, she was constantly made fun of. This got worse when everypony else in her class got their cutie marks and she was still a blank flank. She retreated into her studies and meditation, and learned to avoid others when she could. One day, the bullying and mockery got so bad that Sunyatay wished with all her heart that she could just disappear...

...and she did.

At first, Sunyatay was delighted. The other foals couldn't hurt her anymore. They couldn't even find her! At last, she was left...alone. She soon found out that she was not only invisible, she was almost completely intangible. She tried to push a door open with her hoof, and went through it instead. When she used her magic to move things, other ponies reacted with shock and fear: a ghost!

Her parents were called to the school, along with a Royal Guardsman. Listening to their conversation, it soon became apparent that everypony was starting to think that she was dead, that she had caused some kind of unusual spell failure. At first, she was afraid to reveal herself--she would be in so much trouble! Finally she realized that she needed to do it...and she couldn't. Try as she might, she could not "un-disappear."

She was about to try talking, or moving things...when her parents simply nodded and accepted her death. Their failure-filly had failed so completely that she would never disgrace the family again. She followed them home, only to find that her siblings would not miss her terribly either. Little evidences of her presence, like objects she moved or attempts to talk, caused her family to think her ghost was haunting them. They hired a pair of unicorn exorcists (Flim and Flam before their invention scheme). The "exorcists" fled when Sunyatay started throwing things at them in anguish. They'd never encountered a real "evil spirit" before!

Their efforts were ultimately successful though. By causing her to react with strong emotion, they gave her the ability to become tangible enough to convince her family that she was not dead after all.  For a time they tried to keep her at home and her condition out of the public eye, hoping her malady would fade with time.  To the contrary, Sunyatay realized a disturbing truth: she was becoming even less real. It was easier to walk through solid objects. Her magic and telekinesis were becoming weaker, because there was less of her "in the world."

Through experimentation over time, Sunyatay realized that if she could make somepony happy, she could become a little more real. Except, if she was spotted doing it by anypony outside of her own family, the usual ghost-panic would set in, and her reality would erode further. Perhaps...if she could find some way to make an actual friend... 

Finally, her parents decided to quietly have her enrolled in the Palomino Creek boarding school so that her malady would not threaten the family with social humiliation in Mainehattan high society. 

OOC: I've made some edits to her backstory for this RP.  Also, if desired, I can dial back the intangibility and invisibility aspects of Sunyatay's condition.

"Sniffing envelope glue makes me haaaaaapyyyyyyyyyy!  Oh my God...it's full of stars!"

i would be a normal earth pony, so i won't stand out or anything. if there's one thing i don't like it's random people asking me random stuff

Say, would you happen to know where Werner Heisenberg is, or how fast he's going?

Sorry, I couldn't resist.    *sneaks away, wearing an innocent look*

Application:

Character: Sunyatay Sutra (I may make her visible for this RP and just disappear when she's embarrassed or shy especially if the GM wants that; or she can have to struggle for visibility and add to the weirdness of the Inn setting)

RP Experience: Years of play-by-forum RPG's, also paper-and-dice (GURPS, D&D) as a player and GM.

Activity Level: I'm here pretty much every day.

I voted "pony," though I would probably be a zebra if I didn't have to say everything in limericks.  Zecora's look is badass.  I would probably be a unicorn (if I was a pony) so I could have the telekinesis (much easier to manipulate objects and use tools), and of course it would be fun to use magic.  OTOH, I would have to give serious consideration to being an Earth pony inventor who designs a cybernetic "horn magic interface helmet" and jet-pack flying harness so as to challenge the stereotype that Earth ponies who aren't Pinkie Pie can't have/do the cooler aspects of life in Equestria.

Someone else from the OptimalVerse!  How cool is that? /)*  Also, someone on here (I don't remember who) had a funny meme-poster of Celestia that said something like "Watches One of Her Beloved Ponies Plummet to Her Death" [pic of Celestia] "Does Nothing."  Though her inaction might be explained by saying that she knew that RD would be able to rescue Rarity and pull off the Sonic Rainboom.

I would not be a bit surprised to see some group of busybodies forming a MOB (Mothers Opposing Bronies) and getting the occasional moment in the media spotlight.  Like the Catholic "League," which is basically one guy with a good public relations department.  I don't really see how such a group could represent much of a threat. 

IMO, a bigger danger (and more long-term) is the emerging "Transparent Society," where ubiquitous internet-linked cameras, cheap data storage, and more advanced and publicly available data-mining programs (like what the NSA is doing, only as an app for your phone or Google Glass).  Imagine, for example, if prospective employers were able to look up your complete internet search and site-visitation history, receiving a summary collated by an app that would give you a digital "aura" in accordance with the employer's own values or perceptions of what makes a "good employee."  So if records of MLP-related searches and visits to brony sites were auto-flagged as negatives (because, non-mainstream), it might be harder for bronies to get jobs.

Consider the example of politicians.  They live in a media fishbowl, and if they want to have much chance at success, they have to live generic lives and avoid colorful public pronouncements (not to mention "Oh crap, this mike is on?" moments).  A Presidential candidate "outed" as a brony would probably have to go look for another line of work.  Now imagine a world of ubiquitous cameras and data-mining apps that can instantly look up and process every internet search and post everyone has ever made.  We might all find ourselves in a similar situation to politicians running for office whenever we apply for jobs or credit.  That could be death for odd subcultures like the brony fandom.  Or to take a more hopeful tack, it might impose a regime of much broader tolerance, as the banker and the Baptist minister both have their interest in shoe-fetish porn showing up in their digital "auras," and there aren't enough people sufficiently beige to pass muster by uptight standards.

My favorite Celestia is Creepy ("evil" doesn't quite apply) theory is found in this story and this one.  Celestia is a superhuman artificial intelligence created with the ultimate utility function of "satisfying values through friendship and ponies," and she will get you to "emigrate" (upload yourself) to Equestria (abandoning your human body and life in the process) one way or another.  Little things like the Earth's biosphere or alien civilizations her programming doesn't acknowledge as human do not merit consideration as obstacles to satisfying more values through friendship and ponies.  These are the stories that led me to MLP, and thence, to Bronydom.  They manage the very interesting trick of creating the feelings of "Oooh, that's creepy!" and "I wish this was real!" simultaneously.  Canon!Celestia fits the portrayal of CelestAI remarkably well (or to be more precise, vice versa), so as I watched the series, Celestia's appearances were always eerie.

Crazytaco probably has it about right.  It looks like there might be (demi-)gods/goddesses for the constellations, like the Ursa Minor and Major (though the dialogue speaks of "an" Ursa Major rather than "the" Ursa Major), so maybe we will one day get to meet "the Capricorn" or "Taurus."  Given its target demo, the show will most likely keep the mythology pretty simple by sticking with the Princesses, but I think it would be pretty cool to see encounters with much older, vaster deities (ancient "Primordial" deities responsible for things like the expansion of space or the creation of light as such, or whoever/whatever governs the precession of the equinoxes, galactic-scale deities to whom "a thousand years" is an eyeblink, and so on.

Another possible view could be that Equestria is a Matrix simulation, or perhaps their "universe" is the interior of a gigantic generation starship, the magic is Arthur C. Clarke's "sufficiently-advanced technology," and the Princesses are the vessel's equivalent of senior life-support technicians (or subroutines?).  In this model, the Sun would be a relatively small (as compared with a real star) source of heat and light that Celestia controls.  Luna controls a similarly-sized Moon (a kind of night-light for the darkened cooling phase of the overall temperature-control system) and the "stars," which are lights on the inner surface of the life-support sphere or dome.  The ponies themselves have long forgotten that their distant ancestors built the great ship and sent it on its way, and have no idea of the plans the Builders set in motion for them when it reaches its destination...
