I think it's CadAnce

Well, as a person who considers Cadence the second best pony I still have to say that she hasn't come through any significant development. She had her wedding story - yes - she showed a character there, yes. And something similar with the Crystal empire. But seriously, character development looks different. That means she changes based on circumstances. Nothing like that happened to Cadence.

Still the best princess n__n

I really love Cadance's character design! As for why people dislike her... I've read that it's because she's a 'Mary Sue'.

Is there a Rainbow Dash version?

Awwwwn, I really like her and how she sang on that episode with the 'fake' Cadence togheter. :3

Is there a Princess Celestia version? :3

Yesss

Higher taxes for all working class ponies! Effective immediately!

*3 days later*

Hey guys lets go overthrow the empire!

Great Idea Rarity! These taxes are driving me crazy!

Oh please, you working class ponies are so pathetic, just marry a rich stallion like I did and your problems will be over.

are you kidding, we can't ALL do that, that's crazy! You've never worked a day in your life, have you!?

The taxes are so high I was forced to close my flower shop! Now I can't afford my rent! I feel faint! *faints*

The bank is taking my carrot farm away, I can't pay the new property taxes on it! Whatever shall I do!?

They took my toothbrush.

... ...

Oh come on now girls, it's not all bad. With taxes this high the school was shutdown. Now I don't have to be in that smelly classroom all day!

Yea, heh, good for you. Later losers. *walks away*

*meanwhile in Cloudsdale*

I can't believe they're closing the weather factory.

how will we exist in a world without weather, without rainbows, without clouds?

Rainbow Dash!

yea?

in my office!

*at Spitfire's office*

Ok Spitfire, what's the deal, why is the weather factory closing!?

Dash, this is a matter of national security. Top secret government information. I'm only telling you this because I know I can trust you.

What's happened, is there a problem in the government?

Yes, there is. The truth is, ever since Princess Celestia disappeared Princess Cadence has brought turmoil to our political structure.

But Cadence is a good ruler, I met her before.

Something has gone wrong within her. In the past three days she has put thousands of ponies out of work and raised taxes to such a high level that ponies are beginning to starve in the streets.

Ponies are really beginning to starve? That's horrible. Why isn't Luna doing anything to stop this?

... ... Soarin, please tell her.

The truth is, we think Princess Luna tried to stop Princess Cadence from enacting these new laws, but something happened.

Oh please don't tell me... ... is Luna alright?

We believe Luna has been imprisoned... and... it's possible that Princess Celestia...

... she's...

She's what!?

She's dead Dash. We received the information twenty minutes ago confirming it. We had been hoping to find her alive, but... ... it wasn't to be.

No. No!
No! It can't be! I don't believe it! I can't believe it!

Dash, we don't need this now. This behavior solves nothing.

I can't...
I can't take it!

Damn it Dash! Pull yourself together! That is an order! So help me if you don't stop! Now is not the time!

Oh Fuck you. You would never understand what Celestia meant to me!

Dash! Stop it! Celestia was just as important to me as she was to you!

She meant more to me than you could have imagined...

And how is that!?

Becasue...
...she chose me! Out of all the pegasi in Equestria she chose me to posses the element of loyalty! She depended on me! She granted me more power than anything you could have ever achieved!

... ....

... ...

Fix the damn government yourself.

wait Dash.

... what!?

Your right. The power you posses is unprecedented. I could never... compete with your gifts.

...

Remember your Flight Training with Lightning Dust? Remember how you broke every record in every challenge I gave you? You broke all of them, records I had set. You beat me in all of them...

I-I didn't know.

Well, with that being said...

...are you ready to take orders as a Wonderbolt!?

a Wonderbolt!?
Yes Ma'am!
