Dust of Osiris is the main antagonist and final boss of Melty Blood Actress Again, as well as the main antagonist and final boss of this game. Before the events of this game take place, an epic war once took place in the world of trophies, a war of light and darkness. Leading the darkness was Dust of Osiris, with her giant god-like supercomputer, Hermes, she was practically invincible, all seemed lost until one of the warriors of light, sacrificed herself to seal Dust of Osiris in the realm of Darkness, sending her and her army of demons trapped, while giving her newborn baby a special magic in her heart before departing so that when Dust of Osiris eventually escapes, she can ultimately destroy her. However, Dust of Osiris knew that she can corrupt this "Achilles heel" to turn the tables on her foes by taking control of her to revive herself at full strength and continue her plan to wipe the universe and reconstruct it in her own evil image! In her weakened state, she appears as a small orb of shadowy, reddish darkness, one that you can hold in the palm of your hand. While she isn't able to do much, she is able to speak and perform minor actions, her escape was assisted when she created Dharkon to break open the gates of darkness. She convinced several of the most dangerous, cunning, intelligent, and downright sadistic and powerful villains to form the syndicate, The Agents of Darkness, where she can activate her plans and her new minions will carry out her objectives. In the end she finds Shantae is the chosen one who holds the heart of the Genie Realm in her heart and after her minions torment her and torture her, she finally gets ahold of her and possesses her body as she slowly revives herself making Dust of Osiris reborn once again and plunges the world in darkness, setting the stage for the ultimate final showdown!

Note: She acts and thinks like a computer. She sounds stoic and dominant. Would like it if she has a slight British accent in her voice, and if possible, can use some fancy editing to make her voice sound a bit distorted to emphasize that she's a being of darkness.
