Unicron has returned, and the Chief, after consulting with Cybertron High Command, authorizes CODE M, use of the ultimate weapon.

A crack team of commandos infiltrates Unicron's new form, and makes their way to his spark housing.

There, they hook up a smallish box, and set a timer, rushing out with unseemly haste. The timer runs out, but rather than an explosion, a data connection is made, and Unicron hears a single phrase, one that chills him to the core of his being:

"I'll have you know, I'm feeling very depressed..."
