I agree with the dude above. Branding and designs are crucial for any startup and project launch. While using the name Kratos (or Cratos) is fine since that name has been established since the entire Greek mythology is born, the face and entire look you guys used (bald old guy) has been designed by Charlie Wen from Santa Monica Studious. If ever this project gets successful, I'm pretty sure you would want to avoid legal problems with such a big company due to copyright issues. So, I suggest just removing that old bald guy from your website and hire someone to create your own avatar or arts and whatnot.
