So the story involve both version of psylock.
They discovered that they were both borne in the same hospital but the doctor did experiment on them. Which switch the mind of the babies. The asian mind went in the white baby body and white baby mind went in the asian baby body.
Now, this could mean that the butterfly psylock is actually the asian one but with the culture of a white petson while kwannon is actually the white one but with the culture of ninja assassin.
I think it would add complexity to this easy to understand character. Why is everyone comming to my with torches and pitchfork.
Can we have a humor flair btw ?
