Yes as most know,everyone's favorite egghead of a unicorn is going to become an Alicorn/pegacorn princess this season 3 final. I'm one of the sane majority of fans that finds this change completely okay.
This is Twilight Sparkle's story not Naruto's. (No offence meant to those who like Naruto because I like naruto to.)
Shes not some vapid headed unicorn who mocked the students who actually wanted to make something of themselves while having no skill of her own. Shes also not by some "convenient" luck of the gene related to Celestia and luna. No genie granted her a magic wish to be skilled in what she is.
She trained herself and is getting rewarded for what she worked to do. According to the writers she'll still be the same Twilight sparkle we all know. Some weird rumor said she'd be voiced by Morgan Freeman but it was likely a joke or there could be a lady with the same name we've never heard of.
I see Alicorns/pegacorns like greek gods. There's one for almost everything and there stronger then the average species there based on yes but not 100% invincible.
So to list thus far:
Goddess of the Sun: Princess Celestia
Goddess of the Moon: Princess Luna
Goddess of greed: Queen Chrysalis
Godess of Love: Princess Cadence
Now a demi goddess of Harmony Twilight Sparkle.
