Twilight Sparkle G5 concept!
 
I know I’m later to the train, but after a long break I finally got back into enjoying MLP again! And obviously I’m intrigued by the prospect of a new generation, personally, I think the ‘Slice of Life’ is G4.5.
 
I was interested to see Twilight as an Earth Pony, and in my headcannon, I imagined her to still be of unicorn heritage (hence the lighter frame, cloven hooves and unicorn tail). And I still imagine her to be a large book / science nerd, with an interest in the magic of everypony. While not a conventional form of magic, she is able to channel a magic of-sorts through the use of special crystals.
