Duvalia is a stage in the life of the Type 3 Plaga, a genetically modified species of Plaga engineered by Tricell. Its name is derived from the Duvalia, a species of carrion flower found in tropical Africa. Its most recognizable feature is a large bulb found inside five shorter appendages, which the Plaga mimics with its armored shell and vulnerable core.[excerpt 1]
The Type 3 Plagas were being experimented on in humans from Summer 2008, with research taking place on the Ndipaya and Sodibaya tribesmen who became known as Marshland Majini. By 2009 the guards working on Excella Gionne's cargo ship were also implanted with this Plaga type.
Overall, Duvalia are more commonly seen in Base Majini.
