Oh come, Doctor, We understand that this is only been a few minutes since you have changed, but we are needing you on an important mission.

We foresee a future. The Earth will be invaded by a menacing android race known as the Valde who seek to become the dominant rulers of the universe. We'd like you to stop the invasion at a point in time before it even occurs.

Excellent, however, you will not be alone on your mission. We will send out one of our CIA agents to assist you on your mission.
