Discord: All I wanna do is see you turn into a giant pony, a giant pony...

Tia/Lulu: Shut it.



Coooool. It's great to see the actual showdown.



Actually, I've long headcanoned that something like this is their true form. Eternity gets dull and being the only one like yourself gets lonely. This one God-Pony sees the bonds between her creations and the only way she can experience "the magic of friendship" for herself is to separate her being, and the two ponies she became would have each other.
