At diference of a snow leopard or any white animal,Shiva don't had spots.
So do Kali. The spots that still in the skin of the black panthers just don't exist on Kali's fur.
This its something that its of Kali's Dinasty,where the descendents of the first Warrior Panther.They were pure black,no spots or something,just the scar,mark of the sword of the fallen Wolf of Light,in the Last Battle of The Spirits.
Shiva was the brother of Kali.
He is white as the snow,and his eyes are blue as the bright nights in Valinor.In his eyes are the bright of the stars that Varda-Elbereth forje.
But he was expulsed by his mother,and he become a servant from the Draug Prince. His memories of the times with Kali were deleted,and only anger and lust was in his heart. The bright of his eyes shut down,and they now shined with the anger of his heart.
Soon,the anger will banish. Becouse his destiny its other than be just a beast under Manuel's control.
Shiva have power upon water,light and ice,and he have blue wings.Kali have power upon fire,metal and darkness,and she have bat wings.

OPPOSITE ELEMENTS BROTHERS RULE!!!
