Carla Radames is one of the two main antagonists (alongside Derek Clifford Simmons) of the 2012 horror videogame Resident Evil 6, and the overarching antagonist of the manga series Resident Evil: The Marhawa Desire.

She was originally a genius researcher who became a doppelganger of Ada Wong upon working for Derek C. Simmons and is also the one responsible for the discovery and creation of the C-Virus. She is also the founder and leader of an Umbrella Corporation-type terrorist organization called Neo-Umbrella.

<Biography>

In her youth, Carla Radames was a highly talented intellectual and began to familiarize herself with genetics work, finishing a doctorate by the time she was only fifteen years old. Her extreme intelligence eventually piqued the interest of Derek C. Simmons. She began to work for him in the development of viral agents and bio-organic weapons and in 2001 began work on what would later become the C-Virus. Carla's work on the virus began with a sample of the T-Veronica Virus that she had obtained, intending to use it as the basis for her new virus. Managing to isolate the mutation characteristic found in the Progenitor Virus and subsequent viruses, she succeeded in creating T-02. She created the C-Virus by combining the t-02 with a sample of the G-Virus that had been obtained from Sherry Birkin, which would result in what Carla referred to as the perfect virus.

Carla came to fall in love with Simmons who cared nothing for her feelings. Meanwhile Simmons himself, after his interactions with Ada Wong in 1998, became infatuated with Ada Wong. This infatuation turned into an obsession after she rejected him, provoking him to go out of his way to begin Project Ada, operating out of a laboratory in the Quad Tower in China. Project Ada was a series of experiments with the express purpose of essentially creating another Ada Wong, an Ada that would feel for Simmons the way he did for her.

Carla Radames was the key researcher behind the experiments, trying to utilize the Complete Mutation aspect of the virus to control its outcome. For years, Radames did everything in her power to utilize her newly created C-Virus to try and make Simmons' wishes come true and create the perfect new life form for him. However, time and time again there was only failure. She attempted the experiment thousands of times, resulting in such monstrosities as the Lepotitsa & Gnezdo, but there was no successful recreation until the 12,235th attempt - the attempt that used Carla Radames herself as the test subject although she was tricked into it, unknowing that it would turn her into a loyal clone of Ada Wong, Simmons having taken advantage of her love for him. It was due to her genetic structure that, as Simmons discovered, she would make the prime candidate for Project Ada.

On April 30 of 2009, Carla Radames' body was successfully reborn in the perfect image of Ada Wong with her mind fresh to be molded by Simmons. On that day, Carla Radames ceased to exist, and she was only known to herself and to Simmons as Ada Wong. The evidence of this birthing was found by U.S. government agents Leon Kennedy & Helena Harper in Simmon's Underground Lab beneath Tall Oaks Cathedral (Leon's campaign), and later by Ada Wong herself when she saw the video, in the form of a VHS tape labeled "Happy Birthday, Ada Wong" (Ada's campaign).

As far as Carla knew, she was Ada Wong. Her mind was crafted by Simmons himself, replicating not only Ada's appearance now but also changing Carla to harness Ada's own intelligence and habits. In her new form, Carla was none-the-wiser, having no idea that Simmons had taken advantage of her for the sole purpose of using her for his own gain. As Carla was made to be the Ada Wong that Simmons had always wanted, the faintest remnants of Carla's true self began to surface in her mind. It caused Carla much confusion, as she believed herself to be Ada Wong and Simmons' soulmate, but something in her mind kept nagging away at her, trying to tell her that Simmons had betrayed her and deserved to have his hopes and dreams crushed before his eyes. At first, Carla did not give in to these desires, throwing away the possibility that Simmons would have ever done anything to harm her in any way. Simmons continued to treat Carla as if she were the real Ada Wong, even providing her with a submarine and complete control of The Family's East Asia soldiers as a gift of her loyalty to him.

However, Carla could not shake her conscience trying to tell her something was wrong. Eventually, she succumbed to these thoughts and began to dedicate herself, in secret, to completely decimate everything that Simmons ultimately hoped for. To do this, she secretly founded the organization she named Neo-Umbrella, operating in China where she had developed the C-Virus and was given authority by Simmons, scouring areas such as Poisowan for test subjects under the guise of testing a new medicine. Her resources in China went into a number of projects, including projects that eventually led to the production of such B.O.W.s as the Iluzija & Ubistvo.

In June 2011, after 322 failed experimentation attempts, the C-Virus was administered to a test subject by Carla Radames only a couple days after he was chosen for the experiment. Although this subject lost his arm during a lab accident, he showed a surprising reaction to the C-Virus despite not being an ideal candidate for the test. Just over a week after the virus was administered to the test subject, he was officially codenamed Ustanak and became personally close to Carla, as she did to him. She treated Ustanak kindly, speaking to him softly and treating him as if she were his mother. Ustanak's admiration for her began to show soon after she gave him the virus, and as such he would follow her every command.

Carla's primary goal of her newly formed group was the production of a B.O.W. known as Haos. Housed in an Underwater Facility built, essentially, like a giant incubator for the creature, Haos was to be a massive behemoth of a creature that would be able to split itself apart. Within its body were organs that were capable of dispersing the C-Virus gas, not unlike the Lepotitsa. These two factors make it ideally capable of infecting the entire world at an alarming rate. During its development, a contingency plan was put in place that if ever Neo-Umbrella's leader were to be killed, the creature would be released regardless of its stage. Though this could lead to the release of an incomplete B.O.W., it would be possible that it could still serve its purpose and that the plan would go unaffected.

Even though she worked behind the scenes to get revenge on Simmons for what he had done to her, she continued to follow his orders, for the time being, leading to a mission that would send her to the war-torn country of Edonia in Eastern Europe.

<Personality>

Despite being a cunning opponent, Carla is sadistic and charismatic, using her classy and swift demeanor to taunt Chris and Piers.

Her sadism is largely to blame on Simmons; the fragment of her psyche to survive twisted her into an extremely bitter and nihilistic woman. Carla's notes from before she was turned into an Ada clone implied she was originally much kinder; though still willing to creates B.O.W.s for Simmons.

Upon her mutation, Carla seemed to lose what wad left of her mind. Though she remembered and knew that she wasn't Ada Wong, she denounced the original as an imposter and declared herself the real Ada. Though considering she fell at least three floors up and died temporarily upon impact, it's likely she suffered brain damage that stirred up the old persona Simmons programmed in her; causing her insanity to multiply.

"At first, you will be afraid, but don't worry. You're just becoming the monster you always were. You and everyone else on the planet." - Carla Radames towards Derek C Simmons in his last moments as a human.
