Nyx- she was created by an underground research group by using Twilight’s DNA and splicing it with Nightmare Strain, to create the Ultimate Weapon. Because of the illegal nature of the group the facility was soon assaulted by the Vanguards to shut down its operation. Twilight, who was also with the Vanguards, investigated the innermost parts of the underground facility to find out what they were trying to accomplish. She soon discovered that they were creating an artificial being similar to the ones she encountered two years ago. There she saw in a large singular containment pod the product of the groups research, was a little girl. She was cinvinced that it was the same abomination that she fought in the past, but she could not bring herself to destroy it or rather kill a helpless child. So before the Vanguards discover her as well, she quickly left the facility along with the unnamed child.
