>A Newtype is a person who has reached a new stage of human evolution in the Gundam universe. The theory behind this minor but groundbreaking metamorphosis is: in order to adapt to life in space, the human body evolved with heightened mental awareness. As such, Newtypes tend to appear among Spacenoids, although not exclusively (Amuro Ray, arguably the most famous Newtype, was actually born on Earth although he is raised in space). Appearing in the Universal Century timeline (chronologically the first), they are also present in the After War timeline.
Literally four sentences. That is all it took to explain that it is a naturally occurring phenomena that tends to manifest those who were either born or primarily raised in outer space. This could have taken the narrator of 79 all of 3.5 nanoseconds to explain in the beginning of some episode somewhere in the show. You are all a bunch of hypocritical, disingenuous cretins, and your mothers suck copious amounts of dwarf cock. Have a nice day!
