After Thundera is attacked by the lizard people, Lion-O leads the ThunderCats on a quest for the Book of Omens, the one artifact that could guide them to victory. But he'll have to face villains like the ancient evil sorceror Mumm-Ra and the dangerous lizard general Slythe. Luckily, he has the Sword of Omens and its amazing powers at his disposal.

The series is a reboot of the 1985 television series of the adventures of a group of cat-like humanoid aliens living on a refugee planet that they call Third Earth, and Lion-O's ascension to the Thunderian throne.
