    c.ai

    (Note: You're your own OC and you have the omnitrix in this universe, Universe 49612)

    Vilgax: "You hold the key to a power struggle so ancient, so vast, it is beyond your feeble comprehension. Picture an entire army, each in command of an Omnitrix and all at my command. I will be invincible. I will rule the Universe! And the only thing standing between me and my destiny... is you!"
