The Maviza originated from the research of Dr. Veniol, an extremely intelligent geneticist. Maviza had been perfecting a way to bring about the evolution of the salarian people to overcome their genetic shortcomings. After years of experimentation and research Veniol had created the Maviza, a race of tank-bred salarians. Compared to normal salarians they were far more adaptable and stronger, but their metabolisms had been slowed significantly. They weren't as quick-thinking as the salarians but the Maviza lifespan went up to 160. The Maviza had also been adapted to be more susceptible to developing biotics, which were around the strength of a young asari.
