The new Soul Calibur VI appears to have a very customizable character creation mode. So naturally, some people have been trying to create Krystal! I've found three different versions so far.
The first is the video above, a tutorial by WraxTV on how to create a Krystal character.
Then, there's this video of a fight between a custom Krystal character and Kratos from God of War posted by ZEBRA10045.
Lastly, there's this image, featuring a more colorful outfit for Krystal by beardalaxy.
