A time bandit, as she appears in World War X.

Time Bandits are a group that appears in World War X and Fighters of Lapis 6. They appear after four timelines end in failure and appear to stop you. Initially, they join the enemy to stop you, but begin to get more desperate as they kidnap or murder members of your group.

The time bandits all wear goggles and black clothing. They apparently originate from the timelines that were deemed failed, and they are pissed off about it. They are not the main antagonists, but they do appear as enemies.
