#492, Shaymin, the Gratitude Pokémon
The flowers all over its body burst into bloom if it is lovingly hugged and senses gratitude.
Because Shaymin lived in Flower Paradise, she never knew about the Epidemic until much later when she finally decided to take a flight in sky form around Sinnoh. Shaymin at first thought humans did experiments on these pokemon, however, upon closer inspection, she found out that pokemon caught some disease. The little Gratitude pokemon was shocked, and thought about her other legendary friends. Especially Giratina, remembering the battle with a pokemon hunter 600 years ago. The Shaymin gathered up all the herbs she can get and immediately set off to Johto, where she believes that's the source of the problem.
~ Movie reference for Shaymin caring about Giratina [Check Pokemon and The Sky Warrior!]
~ Shaymin Land Form is more of a healer rather than a battler, which is why she has herbs and her moveset.
~ Shaymin Sky Form is more of defensive; Using energy ball to distract her foes and Leaf Storm to trap them as well.
~ Shaymin is working on finding a cure for the infected and spends lots of times around herbs, she's still looking for the correct combination.
