Didn't you watched The Mysterians? Try reading its plot section to get to my point.

"The proposed interbreeding with women on Earth would produce healthier offspring and keep their race alive."

That's the main reason why the Mysterians wants Des, also their planet was destroyed by the Xiliens. so the two alien races fought using their kaijus: King Ghidorah, Gigan, and Saibogura.
