During the Thundercats round table at WonderCon 2011, we had the chance to speak with Larry Kenney, the voice of the original Lion-O and the voice of Claudus (Lion-O’s father) in the new 2011 reboot. We were also lucky enough to get to watch him perform the complete Thundercats call to arms, which you can watch below.

This will be one of the last time Kenney will be performing his famous battle cry, as he later says in the Thundercats panel that he’s retiring from it and passing the torch on to Will Friedle, who plays the new Lion-O.
