Complete Mutation is the twenty-eighth chapter in the Resident Evil: The Marhawa Desire manga series. It was first published in Weekly Shōnen Champion Extra's 2013 series, but was later on re-published in the fourth tankōbon volume on May 8.
Bindi Bergara begins to emerge from her Chrysalid, taking the form of a giant spider-like creature. Elsewhere, Cpt. Chris Redfield and Ricky Tozawa rush through the school to the roof. As they no longer have radio contact with Biji and do not know where she is, the best way to figure out her location is by looking down from the roof.
Now fully emerged, Bergara towers above Biji, and only part of her face and a lock of hair is left to show her human nature. Recognising the danger the kukri represents, Bergara quickly knocks it out of Biji's hand, before knocking her over with such force she begins coughing up blood.
In a flashback to 2009, Biji is working in the Far East Branch HQ's lab. She is watched by other researchers, who discuss the rumour she got into the job after losing her parents in the 1998 Raccoon City Destruction Incident. Completing her latest piece of research, she requests reassignment to the Special Operations Unit. Sent to their training centre, her progress is monitored by the higher-ups along with Dr. Doug Wright, and it is expected she will be washed-out in a month and moved back to the lab. Despite not having the stamina, her will is strong, and she continues training. After a year, she is excelling in practice matches with other trainees, earning the attention of Cpt. Redfield and Piers Nivans.
