Evil multiverse

You've done it! You've cracked the secret to multiversal travel! Strangely enough, you seem to be a constant. Across all universes, there's some version of you. And in studying these other yous, you've learned two horrible things. One, every version of you has immense potential, with some having become truely universal entities. Two, you are the only good version. And you've just put yourself on the radar of all those other versions. You have vast intelligence, and the capability to build basically whatever you focus on, with time and resources. How will you survive?
