The oldest and wisest of the new ThunderCats, possessed of a great clarity of vision, all the ThunderCats look to Lynx-O for insight. Lynx-O uses his blindness to his advantage, with his lack of sight enabling him to always look beneath the surface for a heart of a problem. Lynx-O's calm, rational personality provides the perfect counterpoint to Pumyra and Bengali's more youthful temperaments, and as such is very much the vital link within their team. Lynx-O, Pumyra, and Bengali tried to board the Thundercats flagship as it left the dying planet of Thundera, but by the time they got close they were too late. Fortunately they were rescued by a pair of Berbils, their ship was damaged and crashed on Third Earth, on a desserted island where the Thunderians and Berbils made their new home. When Mumm-Ra discovered there were other Thunderians on Third Earth, he sent the Berserkers to capture them, The Thunderians fought hard against them, but were ultimately captured. After being taken to Fire Rock Mountain, the Thunderians eventually managed to get away.
After reuniting with their fellow Thunderians, Lynx-O was the only one among his friends who knew that they had been saved by Lion-O, Lord of the ThunderCats, and Lion-O made he, Pumyra, and Bengali ThunderCats.
Realising the threat posed by the wise Lynx-O, Mumm-Ra once ordered a being called Amortus to destroy Lynx-O. While piloting the ThunderStrike, Lynx-O was attacked by the Amortus and the Thunderstrike crashed, after crashing the Amortus touched Lynx-O's face, and used his powers to make Lynx-O believe himself to be an outcast. Lynx-O left with the Amortus for the land of no return, when there, the Amortus again touched Lynx-O, and he began to turn to stone. But the other Thundercats were coming to rescue their friend, and Lion-O freed the other warriors kept imprisoned by Amortus, and they soon defeated their captor. Lynx-O was free, grateful to be back to his old self.
