Martians are my favorite because of their psionic "big brain" internet community where they all can experience a connection no other race can also you can still be am individual and a collective whole when you feel like it so it pretty cool. The psionic biotech is a plus not to mention shape shifting organic clothing and bioship gosh it an amazing society and let not forget the ability to transfer your consciousness into a hand of yours that was cut off and regrow your whole body that was a cool feat martian manhunter did.
