As I was instructed, the Pony Transformation thread is for female TF into technicolor equines, this thread is for TF of said ponies into something. I have written a few of these, so I will link those:
1)
Mistress Butterfly (Corruption/Goo TF/Mind Control/Rubber) Code: "Always the shy ones."
2)
The Black Pearl (Corruption/Rubber) Code: "Letters from a mare becoming evil."
3)
The Night is Endless (TG/Rubber TF) Code: "Rubber mares galore."
4)
The Biggest Fans (TG/Twinning/Mind Alteration) Code: "Be the hero, rather than yourself."
5)
The Specter (Hive mind/Rubber) Code:"Be mine by being Us."
Since you were so kind to read my plug, here, have a
Twilight TF
