Kokiri have Deku Tree as Deity, zora have Jabu Jabu and Goron have Biggoron.

Why Biggoron? I have reason:

-he have supernatural powers

-4 Biggoron is very big and strong, he must be their deity. Is so obvious, a fool could see!

-He also make sword stronger then Master Sword. More proof that he is.
