My suggestions for legendary Pokémon:
Upper left: Veridi, Fairy/Bug-type
Upper right: Aestas, Fairy/Fire-type
Bottom left: Autumni, Fairy/Grass-type
Bottom right: Hibernis, Fairy/Ice-tpye
Description: These legendary Pokémon roam the land of Armai, maintaining the balance of the seasons. Veridi governs spring, Aestas governs summer, Autumni governs fall, and Hibernis governs winter. (I will add more if you think they're OK.)
Dex entries:
Veridi - Known as the fairy of spring, this Pokémon brings new life and awakens that which has been asleep during the winter.
Aestas - Known as the fairy of summer, this Pokémon goes around spreading endless energy that allows for the growing of things.
Autumni - Known as the fairy of autumn, this Pokémon blesses harvests and brings good crops. It also changes the colour of leaves.
Hibernis - Known as the fairy of winter, this Pokémon lulls the tired nature back to sleep so that it can start anew at the beginning of spring.
Signature move: Nature's Boon
Attack Power: Sp.atk 80
Type: Fairy
PP: 5
Other: The user gathers the energy of the nature and releases it in a flurry of light. Depending on the users ability, this move will have different effects.
Ability:
Veridi - Spring Aura: If the move Nature's Boon is used during spring, it will have 100 Attack Power and be of the Bug type. Using Nature's Boon during spring also makes the user recover a bit of health.
Aestas - Summer Aura: If the move Nature's Boon is used during summer, it will have 100 Attack Power and be of the Fire type. Using Nature's Boon during summer also makes the user recover a bit of health.
Autumni - Autumn Aura: If the move Nature's Boon is used during autumn, it will have 100 Attack Power and be of the Grass type. Using Nature's Boon during autumn also makes the user recover a bit of health.
Hibernis - Winter Aura: If the move Nature's Boon is used during winter, it will have 100 Attack Power and be of the Ice type. Using Nature's Boon during winter also makes the user recover a bit of health.
Oh, and about Sheeper's move. I was only planning on having it learn it upon evolving into Fleeceram, perhaps one of those moves it learns instantly upon evolution? Or perhaps even later.
