Shaymin's personality varies depending on the form. In both forms, it goes where there is gratitude, and will meet up with others of its kind, and migrate somewhere else.
In Land Forme, it is shy and easily scared.
In Sky Forme, it becomes playful and courageous. It also adopted dog-traits like shaking itself dry or by scratching itself with its hind legs.
Powers and Abilities
Shaymin has the ability to absorb and purify any polluted air within its body, and releases it in a violent explosive burst. In Movie 11, the people in Floaroma town admits that the town was initially a barren wasteland, and celebrated Shaymin's ability to produce grass and a rare type of flower (Gracidea).
Hence its secondary form, it has the ability to fly. It reverts back to its base form either at night or when frozen.
Whenever there's any impending danger, it can escape peoples notice by camouflaging itself. It is capable of telepathy, and can sense the genuine gratitude of others.
- Shaymin is based on a hedgehog, although the grass on its back makes it bear some resemblance to a chia pet.
- Shaymin is to date, is the smallest Legendary Pokémon.
- In its Land Forme, it is the only pure Grass-type legendary Pokémon (not counting Arceus with the meadow plate).
- The Shaymin in the 11th Pokémon movie was voiced in the English dub by Amy Palant, who also formerly voiced Tails in the Sonic the Hedgehog franchise, as well as numerous other Pokémon characters. That Shaymin even sounds like Tails (as voiced by Palant) when in its Sky Forme.
