Kai reminds me of Illidan Stormrage from Wow

The first time I saw Kai in chinese trailer of KFP3 he immediately reminded me of Illidan Stormrage from world of warcraft,when I saw the movie I noticed alot of simmilar things between theese 2 characters.

-both have green weapons
-both have large horns
-both have green eyes
-both have long hair
-both are shirtless and have simmilar clothing
-both were banished/imprisoned for something
Kai got banished to the spirit realm for 500 years,Illidan got imprisoned for 10000 years.
-Kai finally absorbed Master Oogway's chi wich made him strong enough to exit the spirit realm and return back to the mortal realm,Illidan absorbed the skull of Gul'dan wich he became powerful.
-Kai has those green jombies wich he spawns from throwing green amulets,and if im not mistaken Illidan has those 2 green ghosts that each comes out of his sword(like in online boss fight where he flies up high in the air and throws both of his swords in the ground and ghosts come out to fight).
