Some big news came out of WonderCon this past weekend, and while that Green Lantern footage took the internet by storm, we have yet another piece of video that might get you excited. It’s the new trailer for Cartoon Network’s all-new Thundercats animated series. I can’t say that this is exactly my cup of tea, but I’m sure plenty of grown up nerds will want to introduce their kids to the characters who made their childhood cartoon-watching days so great. Based upon the iconic 1980s action classic, Thundercats tells the epic tale of Lion-O and his battle against evil in the quest for the fabled Stones of Power. Check out the new trailer after the jump.
