I have looked over and I only found 1 fic, I recommend reading it and would like someone to make more for the second, third, and fourth movies. But in my opinion Rainbow Dash should be Raph, because Applejack is more level headed like Leo.

I like it to anthro, and Casey and April are replaced by OC characters.

Splinter - Celestia, Keno- Scootaloo, Shredder- Nightmare Moon, Foot clan - humans, Ken-Spike, Mitsu-Rarity, Walker-BlueBlood, Winter- Discord.
