How do you get Wong Leung?

To get Wong Leung, use Kou or Volt to beat Kaldea in the Galeos, then use Sion to beat Dauragon. When Sion is standing outside the bar, he will have a dream where you have to fight him. Beat him to unlock him.

First off it is a pain to do this over and over again so get Sion, Volt, and Kou all up to rank S so only have to do this once. Start off with Sion in the first battle. After that, only use Volt or Kou for all the rest of the battles. On the last battle which is the one after you defeat the panther onboard the Galeos (gaint space ship) pick Sion and whoop Dauragon's ass as needed. Best way I found to do that is let him go after the other fighters and attack him while they are, and then run around him so he will go after te other fighters again. Any way after you beat the crap out of him that whole ending scene will play. When it goes back to the Bar where it all started at, Volt will come up and tell Sion it is his shift. Then it shows Sion standing out side. He dozes off and flashes back to his training with Wong. They will talk for a little bit then you have to spar with hm. Beat him and he will be avaliable for use in versus, and survival mode. By the way you might want to attack Wong quickly and use your defense sparingly because Wong has two unblockable, strong yet slow techniques, and also one strong throw technique. It took me a total of eight completions to get every character and get then all up to rank S. Have fun and you are welcome!

Beat Kaldea as Sion or Volt and beat Duragon as Sion. Sion will have a dream where you have to fight him. Beat him to unlock him.

It is very annoying to do it over and over again so get everyone on your team to rank S first
