He enjoys presenting as male and female on different days, often confusing ponies who go searching the forest for his expertise. Sometimes Saiya engages in lighthearted mischief giving those looking for him directions to go in circles in the forest leading straight back to him.

Some rumor he can even create transformation potions but he refuses to create such things due to how dangerous they are and how much trouble they could cause falling into the wrong hands.
