Bandai Namco has release a new trailer today that shows off Nightmare, Xianghua, Kilik, and new character Groh.
Soul calibur VI is considered as a reboot as all the characters are reverted back similar to their soul calibur 1 days. So Nightmare appears to be a posses nightmare, Xianghua is pretty much the same, and Kilik has his staff back(THANK YOU).
For Groh though, he is completely new character to series. He uses dual long sword style that he can split into two for faster attacks. Think of Darth Maul but he can split the lightsaber in two.
Also what is wrong with Kilik?
