A fun mini au where the Student Six and the Main Six (as well as a bunch of others) swap species/roles! The main characters won’t be exact swaps, I was choosing species mostly based on vibes. And as if this au isn’t complicated enough I’m also changing their names to fit better with their species naming scheme lol  
• Fluttershy >> Summershy (Hippogriff)  
• Applejack >> Applejack (pony)  
• Twilight Sparkle >> Tinder (dragon)  
• Rarity >> Gossamer (changeling)  
• Pinkie Pie >> Pinkamena (yak)  
• Rainbow Dash >> Graze (griffon)  
Here’s some other characters that are swapping roles too:  
• Celestia (Dragonlord Celeste) = Ember (Princess Emberglow)  
• Luna (former Changeling Queen Locust) = Chrysalis (Princess Mariposa/Currupted version Chrysalis)  
• Cadence (Princess Coral Cadenza) = Skystar (Princess Skystar)  
• Thorax (Thorax Theory) = Sunburst (Sunny)  
• Spike (Spectral Scribe) = Starlight (Sparks)  
Some names may change but thats the gyst. Student six pony forms coming soon! Reference image from the heros wiki here! hero.fandom.com/wiki/Young_Six
