In this special standalone issue, the perspective shifts from the besieged ThunderCats to the attacking Mu'Tants. In the quiet before the assault seen in issue #9, Slithe thinks back over his old life on Plun'Darr, and how his world was shattered by the Great War with Thundera. But even as he readies his forces, other eyes are upon him unsuspected watchers who are neither Thunderan nor Mu Tant!
