He was voiced by the late Earle Hyman, who had played Russel Huxtable on The Cosby Show.
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.
