En guarde!

well her spirit of fighting on form her dad and her spirit of love on form her mom and her spirit of friendship on her aunt!

Badass fluffness! Love these two images with father and daughter bonding. First one with little Flurry watching her dad at royal guard work, then the second one with Shining sparring with older Flurry. And I’ll bet Shining would like her to be both princess and the captain of guard.

I’m not entirely sure what you mean about “Hasbro throw[ing] that out the window”. They never really implied that alicorns aged in any unusual way – if anything, like @mjangelvortex said, we had strong implications that they age the same as normal ponies as far back as the reveal that there were indeed more alicorns than Celestia and Luna.

Equestria could always use more warrior princesses.

I have the small headcanon that alicorns have some kind of “Stage”  
1st stage is Ascendancy to Alicornhood - Normal lifespan  
2nd stage is immortality  
3rd stage ???
 
The grim part it’s that to ascend…the subject need to die.
 
In the episode where Twilight become an alicorn,it REALLY seemed like the elements vaporised her,and after a bit she ascended\resurrected to first stage.  
In the episode where they showed the battle between Luna and Celestia,i always thought that Luna first killed Celestia(first stage alicorn until now)Then She resurrect and banished\killed Luna (first stage too…until now),so they both become immortal.
 
I think that alicornhood is some kind of prize from a superior power for acts of sacrifice or something similar.  
But i dont know how Celestia or Luna first ascended to Alicornhood
 
Remember that this is simply my headcanon ;)

@Autumn_Shy  
Don’t forget that Cadence aged at around the same rate as Shining Armor did.

Hoof feathers…
 
Interesting design idea. ^^
 
I simply adore this, but there’s a part of me that’s sad. I can’t get the headcanon out of my mind how slowly alicorns age. Are we going to see Hasbro throw that out the window, or Shining Armor immortalized somehow?
 
Shining Armor is like the mayfly of the family.

Man does this look great. I love seeing Flurry Heart like this.
