"Nobody tells the Supreme Overlord what to do, except the Supreme Overlord, and that's me! Rosie! And I'm her, and you're history!" Rosie's words after betraying her father, REvil. On the Second Part of the Ultimate Virus Battle Z, after Rosie is now beyond the Anti-Virus Super Deluxe Computer Chips' power as she overwhelms the Anti-Virus Sisters before taking her leave while telling them that the worst is still yet to come. She has some unfinished business to attend to first before she can launch the Catastrophonator, the evil viruses ultimate grandmaster piece. She absorbs more and more data and souls from the rest of the evil viruses, including her father, REvil. Making HER its true ruler of the Multiverse. SHE now has a new look, makeup design and armor to match herself, and the most dangerous virus in existence. SHE is now invincible, unless if Viola can withdraw her back-up card out of her body. Her new look will arrive somewhere in the middle of Part Two of the Ultimate Virus Battle Z.
Credit to everyone! Most credit goes to their owners. @SacLockings4578 for REvil (mentioned) Note: The Anti-Virus Destroyer Suit stays exactly the same when she powers up, except for helmetless. This is not her true final form. Her voice stays the same.
