The trailer for the upcoming Warner Bros. Animation's reboot of the Thundercats cartoon series has been released at WonderCon 2011. The trailer starts off with the narration of the background story. The action will take place on Third Earth and focuses on the inhabitants living in a prosperous culture in the Kingdom of Thundera, ruled by Claudius. The video than moves onto the invasion of the lizard army with the new Lion-O joining in the fight. An interesting note is that the background music for this part seems to drop hints of an update to the classic theme.
The cartoon series will be aired later this year on Cartoon Network.
