Regarding the question about the red insignina. Many people say in the OS it was reserved for the TCs, not the commoners, and base it in the fact that Lynx-o, Pumyra and Benagli never had it until Lion-o turned them into TCs.
BUT, don’t forget in the first episode, “Exodus”, the TCs (Panthro, Tygra, Cheetara and the kittens) were nude, so they weren’t carrying the insignia until Jaga gave them their clothes and weapons (I think Jaga did have it already, would have to check that).
Maybe they didn’t need the insignia in Thundera, but Jaga gave it to them along with their clothes to idntify themselves and be identified in the universe/space/wherever they ship would have taken them to as TCs, and also to create a group spirit among them, something that joined them together and reminded them they were a team overall.
I think that was one of the biggest plot mistakes in the OS. That the TCs were initally nude, but Lynx-o, Pumyra and Benagli were already dressed when the were rescued from Thudera by the berbils, and also that when Lion-o travelled in time and space back to Thudnera before it was dstroyed, the guards also wore clothes. Jaga espcifically told the TCs in the ship something like “while you didn’t need clothes in Thundera, I don’t know what dangers you are going to face in your new home”, indicating he was giving them the clothes only to procure their safety.
