I did this one before I drew the Applejack age thingy. But what the hell. Here it is anyway!
Since it’s a bit of a repost, let’s just jump into the headcanon, eh?
I’ve always figured Shining Armor was quite a bit older than Twilight. So here he is at the age of 8, taking a peaceful nap with his infant sister. At this point of her age, Twilight, like all unicorn newborns, would have a small little bump where her horn will eventually grow in; this bump is covered in fur and very rounded out in order to make birthing easier on the mother.
Anywho, I can easily see Shiny being fiercely protective of the tiny filly, so when he wasn’t at school or out with friends he was by Twilight’s side (they met Cadence much later).
Little Twilight here is throwing a bit of a hissy fit. xD It’s mainly because she really really REALLY wants to be able to do magic, but she’s simply too young at this point. That doesn’t stop her from trying and trying again.
This is where a good majority of one of my headcanons comes in. In this image, Twilight is around 13 or 14, while Spike is a few months old.
The idea here is that, after managing to get into Celestia’s school by an impressive show of magical power, Twilight was given the little hatchling and told that he was her responsibility. Obviously, Celestia and her parents would help Twilight raise the little fella, but she ultimately did it herself.
But, being the named protégé of the Princess of the Sun isn’t always sunshine and roses (if you’ll forgive the pun). I can easily see Twilight being bullied by other foals her age (and sometimes, foals older than her) that were jealous of what she had and how she gained it, and while it hurt, Twi did her best to ignore the name-calling and pushing around. She never told her parents, Shining, Cadence, or the Princess about this either.
That, however, immediately stopped when the focus shifted from her and to little Spike. Some of her bullies thought it was a good idea to mess with the little guy while he was playing in the gardens, calling him a little monster or freak. Twilight, having been in the gardens with Spike, stood up to the bullies for the first time. Yelling and snarling resulted in Twilight trying to take Spike and leave, but one of the bullies shoves Twi away while another made a grab for the hatchling.
That was the last straw, and it immediately turned into a fight between Twilight and the bullies.
Whether or not she won is up to you (I’m personally going with her losing the fight, being outnumbered and all), but regardless of the outcome the bullies leave and she came out of it with a black eye, battered and bruised and a scratch on her cheek (an alternative to how she got that scar). This sketch is when Twi collapses onto the ground, too pained to walk, as Spike clings to her, and the two remain like this for quite a while before they manage to make it back to their room. When Twi’s family and the Princess finds out about the ordeal… well. Let’s just say the bullies were quickly dealt with.
Buuuut yeah. This is one of the few headcanons I have that explains why Twilight had no friends other than the few she had and while she dwelled so much into studying.
A fully grown Twilight lying down, tired and ready for a well-deserved nap but pretty happy. This would be a couple of years after she turns into an alicorn, so by this time her hair is beginning to grow rapidly and she’s still growing taller. Even though she gained the title “princess”, I don’t think she’d be immediately set to do royal duties and the like, especially with Luna and Celestia’s rule being as healthy as it is. So instead, I’d figure she’d be more of an ambassador and knight representing Equestria. I think, eventually, the Mane 6 (Spike too!) in general would get more regularly involved with worldly and royal affairs of all sorts in the future, but for now, Twilight’s the first to be integrated into this sort of career. The process of grooming her into a knight and ambassador for the country is long, vigorous, and often results in headaches and sore muscles, and while it does often bring about stress and doubt in herself Twi has her friends and family to back her up every step of the way. Overall, she’s pretty happy with how her life’s turning out. c:
SSSSSSSSOOOOOOOOOOOOO there you have it. Have a nice helping of headcanon possibilities. c:
Pouty three-year-old Twilight Sparkle is the greatest thing I’ve seen all day.
The rest of this headcanon is pretty fun, too.
