So as stated in the old information "Ghost" got his name hearing that snow leopards were called "Ghost in the Mountains", and many other Snow Leopard super soldiers came with the same idea. This Ghost has the ability to manipulate electrical charge or electicity or Electrokinesis. He can drain power from air targets but ground targets he has to get close to drain their power. But thanks to that he can also power a pulse rifle ( a gun that shoots electical energy and solid round ammo) which Ghost often hates/loves it since it got him out of a lot of jams and bad positions, and also help form Nava helping him too.

Ghost and Nava were paired by the scientist to see if mix breeding of supersoldiers was possible and later to find out it was possible. With Ghost's nano machines inside Nava it took a while for them to adjust to be beneficial to help Nava. When she was Pregnant the nano machines didn't quite help her and allowed Nava to get almost every negative thing to happen when pregnant.

Ghost is a loving husband to Nava even in her bad moods he dose his best to brighten Nava's crapy day with his loving care, his playful attitude, and to cool her favorite food (Bacon and Eggs with lots of Pancakes). Ghost and Nava were later recalled from the front lines with the use of automated turrets to replace them. Ethan and Luna later met them and asked them to join them training the new generation with Ghost being alright with it and Nava just wants to keep her rifle.

SO if you look though my gallery you will see Nava and Ghost do have kids and also what Pregnant Nava looks like. Hope you enjoy this guy!
