The mighty WRO... they wouldn't last a day in Deepground.
Rosso the Crimson is a member of the Tsviets and one of the antagonists of Dirge of Cerberus -Final Fantasy VII-. She is a sadist and her weapon is a unique double blade capable of gunfire, similar to a gunblade.
Slashed, strangled, and slaughtered. Beaten, stabbed, and crushed. Garroted and impaled. Shot and executed without mercy. Nicely said, Weiss. I wonder if this will be a little more amusing than last time.
Rosso is a woman in her late twenties with shoulder-length crimson hair and matching eyes. She has a widow's peak and her hair is styled spiky. Rosso's outfit is revealing; she wears a connected one-piece baring the Deepground colors with crimson sleeves. She wears armor on her lower arms and gloves with spiky fingertips. She wears a long, furry crimson cape that drags behind her, thigh-high boots and torn red stockings.
Rosso is sadistic and loves to kill. She is loyal to Weiss and stated once to Vincent, "If Weiss desires the awakening of Omega, then it is all of Deepground desires." She is a narcissist, declaring that "no one will stand above me!" Like the others Tsviets, she hates the Restrictors the most. It is revealed in the multiplayer mode that she only wishes to go outside of Deepground.
Rosso was born into Deepground in 1985, making her 25 in Dirge of Cerberus. She was the first of the Deepground experiments to be spliced with Genesis Rhapsodos's genes and the success of her birth prompted further research and experimentation on Deepground troops. The rigorous training regiment of Deepground shattered Rosso's psyche, leading to an obsession of bloodying her victims, hence her title "the Crimson".
During the events in the online multiplayer mode Rosso explains she wanted to see the outside world's sky since she had only ever seen projections and decided to kill countless Deepground soldiers to get her point across. Soon after, one of the Restrictors challenges her and though she puts up a good fight, she is defeated. Later on, she is summoned by the Restrictor along with Azul to spar with Weiss.
She is defeated easily, but transforms into Bloodburst Rosso. Though she puts up a better fight the second time, she and Arch Azul are again defeated by Weiss. With the Restrictor near death, the chips implanted in the Tsviets brain stems begin to wear off. Rosso and the other Tsviets laugh as the Restrictor breathes his last breath.
You know, this is the first time I've ever felt the rain on my skin. But then again, I hadn't even seen the sky until a few days ago.
While Vincent Valentine is in Edge, he finds a near-dead World Regenesis Organization (WRO) soldier who tells him of a woman in red who slew their troops in the warehouse and was gathering civilians. When Vincent arrives at the warehouse, Rosso is found to be more than a match for him and Chaos takes Vincent over. Chaos is too strong for Rosso to handle, and she flees.
She meets Vincent again in Nibelheim in the Shinra Manor where she steals the Protomateria, the key to controlling both Chaos and Omega. Rosso is now prepared to deal with Vincent and might have killed him if not for the timely intervention of Yuffie Kisaragi. When the WRO launches its assault on Midgar, Rosso fights Cloud Strife. The outcome is unknown, though both Rosso and Cloud survive the encounter, suggesting there was no victor. Rosso confronts Vincent for the final time in the old Shinra Headquarters where they engage in an all-out battle and Rosso is defeated. Rosso, prideful to the bitter end, tells Vincent their time together is over and that Azul is waiting for him. She tells him he will not have the pleasure of killing her, collapses the portion of the building she stands on and plummets, laughing maniacally, to her death.
She is voiced by Atsuko Tanaka in the Japanese version and Mary Elizabeth McGlynn in the English version, the latter of whom gave her a Romanian accent.
Rosso shares her Japanese voice actress with Ultimecia from Dissidia Final Fantasy and Dissidia 012 Final Fantasy and Arecia Al-Rashia from Final Fantasy Type-0. Her English voice actor also voices Nora Estheim in Final Fantasy XIII.
Rosso is fought as a boss in the Shinra Headquarters.
Her name is the Italian word for red, though the -"o" ending should be replaced with -"a" in keeping with gender, meaning that her name is technically masculine in Italian. Her name is essentially "Red the Red".
