Greg is your average happy-go-lucky precocious guy. Talkative, friendly, and approachable. He has a heart of gold; he's willing to give the shirt off his back to those who need it. Hardworking and eager, his specialties lie in engineering, especially where it concerns exo-armor and exo-suits. While not the best pilot there is, he can hold his own in an exo while in battle. Spends hours tinkering on Exos, but also likes playing video games. Also spends a great deal amount of time in the cafeteria, either eating or learning new cooking techniques.
