Chrome Dokuro
Chrome was chosen to be the holder of the Half Vongola Mist Ring in Mukuro's place. She fought on level footing with Viper during the early stages of her match, but was overwhelmed once Viper got a bit serious. Viper, soon realizing that her trident was the key to her power, began targeting that, and, shortly after, was able to destroy it. This led to an unusual phenomenon where Chrome lost some of her organs, and seemingly the match.
However, soon a mist covered her body. Viper guessed that Chrome did what normal female illusionist do by using the last of her powers to cover her body. Viper couldn't be more wrong, because out of the mist came a sinister laugh, and, once the mist cleared, Mukuro had taken over.
Mukuro soon defeated Viper, winning the match, but having used too much of his power, his grip on his real illusion faded, returning the body back to Chrome.
