As a side product of my MANTIS surgery, I got the ability to split my mind in two. In theory, I could do so infinitely, but my brain power would be spread thin. As of now I had split my mind into 8 parts. This results in multiple "personalities", though really, they are all the person named Vill-V, which is me. I also have a habit of delegating each persona specific tasks and thus specific knowledge, which makes it seem as though I have multiple personalities.
