"The blooming of Gracidea flowers confers the power of flight upon it. Feelings of gratitude are the message it delivers. It can dissolve toxins in the air to instantly transform ruined land into a lush field of flowers."
Shaymin has two formes: Sky Forme and Land Forme; unlike other Shaymin, its primary forme is its Sky Forme due to biological alteration.
The Alexis Saga
Shaymin first appeared in FL019 when it hatched from an Egg given to Lexi in FL009 by Celio for helping him out. When hatched, it was discovered that Shaymin was in fact biologically enhanced while still as an Egg so its primary forme is its Sky Forme, only being able to switch to its Land Forme when given a non-toxic antidote which will suppress the enhancement.
Despite only just hatching, as Lexi visited the Gracidea Meadow, it became apparent that due to its species nature, it could not remain on Lexi's team full time, and therefore, was to be left at the Gracidea Meadow with others of its kind. Despite this, Shaymin was given a small device which meant it could be called upon by Lexi whenever she wanted.
Shaymin has not appeared since.
Shaymin is naturally a cocky and brave Pokémon, who is often boastful towards others. Despite this, it can often become embarrassed when intimidated by other Pokémon, which is gets scared by. It's extremely courageous and playful.
While in it's Land Forme, it can be quite timid and shy, however, it also can be sarcastic and slightly rude.
Shaymin is able to purify any toxins within people, objects or the atmosphere. It delivers a constant message of gratitude wherever it goes.
