Nova Terra? She's a Ghost, someone you don't want to piss off. Nova can shoot the wings off a fly. They are born with special abilities than other Terrans and that suit helps them utilize their abilities. They were trained ever since they were children and are considered the most dangerous Terran soldiers. Most of them often killed their parents and abductors because of their powers. They can cloak, "lockdown" an enemy vehicle, call down nuclear strikes, are excellent snipers, and some Ghosts can mind-control people. Another variant of a Terran Ghost is a Terran Spectre. They are considered more dangerous than Ghosts due to the Terrazine that they use to enhance their powers. Nova would kindly turn you down OP, with a bullet to the head. You're better off banging a Terran Medic.
