Panthro is a male Thunderian and noble member of the Thundercats. His only weakness is his fear of bats. He is the next noble and also the second eldest after Jaga (until Lynx-O is introduced), based on the panther, this warrior is the chief mechanic/engineer and pilot for the ThunderCats.
He was voiced by the late Earle Hyman, who had played Russel Huxtable on The Cosby Show.
In the 2011 remake he was voiced by Kevin Michael Richardson.
Panthro is also physically the strongest and is a cunning warrior in combat, relying as much on martial arts as on physical strength. With Tygra’s help, he builds all of the vehicles the ThunderCats use on Third Earth — including the ThunderTank, the Feliner and the ThunderClaw, ThunderStrike and HoverCat.
A jovial soul, Panthro is, however, also quick to lose his temper (sometimes even with Snarf's pranks) and has a paralyzing fear of bats and a dislike of spiders. In combat, he uses a pair of chained Fighting Sticks (nunchaku) with open-away cat-paws, which house several chemical spray-compounds that he can use against foes. The spikes on his chest bands can be used like projectile weapons or as rappelling lines.
