"Kaido of the Beasts" one piece

"Kaido of the Beasts"   one piece manga 795

 Kaido of the Beasts  (百獣のカイドウ Hyakujū no Kaidō)  is known According to Law, he is "the strongest creature in the world". However, his name in Japanese, its meaning is leading to something referring to all kind of beasts .

as it was shown in the One Piece 795 Suicide  Kaido is  incredibly large and muscular man and So much Tall, obviously as he was standing in front of Kid.

Kaido has tree mysterious things :

1/Devil Fruit: I think he has a zoan type as he leads a zoan army

2/Zoan army: we know that kaido is the principal buyer of the artificial devil fruits  from Doflamingo and Ceasar.

3/Power-Level: Doflamingo fears him, I think it's due to something incredible and out of our thinking, in the first hand because he is a younku, and in the second hand, because he  got such a  strong army.

in the end, I conclude with this: 

Kaido is a damn mystery indeed.

so what do u think about this theory?
