Wes:
What's going on? The call sounded urgent.

Tommy:
I was hoping this day would never come. Andros has recently tracked down the remains of the evil Machine Empire.

Tommy:
We destroyed their leaders, but some of their generals managed to survive. They've been hiding all these years. They've finally regrouped their forces and are amassing on the moon, preparing to invade Earth.
