I noticed that there isn't a thread specifically to discuss these characters in the new series and I don't think I can do as extensive a breakdown of their characters like Grune the Destroyer did with the adult Cats. But I thought they deserved their own discussion thread as well. So here's what I got... OS means Old Series. NS means New Series. OS: The ThunderKittens were pre-teens. NS: The kids are now younger and actually children. OS: The ThunderKittens from all we knew about them, were ThunderCat nobles from the start which is why they were escaping on the ThunderCat flagship. NS: The Thunderkittens are now lower class society. They are little thieves living on their own with dreams of finding treasure and being rich some day. But even though they are lower class, they some how meet up with the ThunderCat nobles and join them. OS: None of the ThunderCats had tails except Snarf. NS: The ThunderKittens now have tails (Snarf still does too). These tails are looked down upon in Thunderian society. OS: The Kittens weapons consisted of lassos and pellets with magical properties. NS: So far we know that Kit plays a magical flute that can put a trance on people and Kat has a rope of some sort. I just gotta say these kids are pretty lucky. It would be like today, someone meeting a celebrity or hero and getting to join them on their adventure.
