CoT, your analysis in the final part of your post, where you estate the new Tygra being empathic and good with people so he could win friends here and there, seems to fit the character well
Of course, in order to get that, producers would have to give him some kind of role in the series, not just stand there next to Lion-o.
I think while in the OS Tygra wasn’t precisely sociable, he was with the Warrior Maidens (although Lion-o met them first, some of their main appearences were almost related to Tygra), and he also had a link with the mole people (I don’t remember any other TC treating with them). I think in the OS he was a sympathetic guy, but intoverted and kind of a loner, so it was hard for him to bond with others (he even seemed to have some limitations interacting with his fellow TCs lol… except for Cheetara, he was with her a lot), but when he got to feel comfortable with people, he bond well (like the Warrior Maidens).
Honestly, it’s not like you saw Tygra going to the berbil village, or Hook Mountain, or any other place. He usually preferred to stay in Cats Lair, go in space exploration missions with the kittens, or get outside by his own either exploring or making some research (that’s why he was usually alone when getting into trouble: “Fireballs of Plun-Darr”, “Garden of Delights”, “Superpower Potion”, etc. :D). I used to think that besides the TCs, Willa and Nayda were his best friends on Third Earth.
And I agree in that he deserves some respect. Tygra is like the Thundercats Aquaman, mocked because of being misunderstood when it comes to his personality and not valued when it comes to his powers and abilities… heck! He even is orange like Aquaman’s shirt lol (Aquaman happens to be my favorite DC superhero ;)). Although I’d think of him like a mixture of Aquaman and Batman (becuase of the brains).
It’s similar to his suit in the old series, wit one sleeve only over the left shoulder, with a lower yellow border. His clothes (before the green armor) was similar to his clothes in the OS, with the crossed chest and all that
