Alpha Draconis member list:
Lt.TDN
Nickname: "The Dragon"
Rank: Lieutanent

Description: A man with black hair and eyes. He is neither too muscular or weak. He is not your typical overmuscular tough action hero. Yet in no way is he an average man in combat. To him, the only strength he needs is the strength to weild his trusty Pulse Rifle. He is an expert in the use of the Pulse Rifle and an expert marksman. A good leader, he command his troops to victory. But as he says: credit is never all his. Unlike the Lieutanents of the typical marine squad who sits in the comfort of their APC during battle, Lt.TDN always go into battle with his men, saying: what fun will it be?

History: Lt.TDN, born on planet Sigma V of the Draconis sector. His parents were scientists working in one of Weyland-Yutani's test labs on Sigma V. At the age of 18, he joined the marines of the Draconis sector for he had always wanted to be in the army. At that time, when the Alpha Draconis was formed, he was given an "invitation" to join. But he turned it down because he thought the threats of these alien creatures were all fictional (caused by Weyland-Yutani media propaganda). Several years later, he was sent to a new encampment on Sigma X. On the same year, specimens of both species on Sigma V escaped, and the whole colony was slaughtered, including his parents. He now realize the threat that these creatures pose and agreed to join the Alpha Draconis squad. During one of the missions, he and some others provided cover fire while colonist survivors retreat to the dropships. For this act, he was promoted to Lieutanent, and he had been that ever since. But he shall never realize that the true threat doesn't come from these creatures, but from his own fellow humans, until the mission on the unknown planet.
