Advanced (Zentradi) biological weapons built by the protoculture hundreds of thousands of years ago. Development on the Evil Series was halted because the power of the weapons exceeded the fighting capability requirements, but discovery of super dimension energy from the sub-universe (as well as internal conflicts within the Stellar Republic) revives the program. Utilizing biological super dimension organs that harvest vast amounts of super dimension energy, seven Evil Series weapons of seven types are completed. Notable are the highly mobile, humanoid "Sivil" for search-and-destroy functions and a super-scale, high-powered "Glavil" for fleet warfare. Tests of the Evil Series begin, but at the same time the biological super dimension organs overload and release extradimensional energy. The Evil Series are inhabited by the Protodeviln from the sub-universe and the invasion of the Stellar Republic begins.
