You knwo they are te first doing that? Kung Fu Pandas are a recurring theme because Pandas are from China where a lot of martials arts were born.
Blizzard used that on Pandaren back in Warcraft 3 and in Warcraft most recent expansion.
Ranma 1/2 has a Kung Fu Panda.
Just two examples and there are plenty more its a normal theme, they can sue people if they could people who though about it before them should sue them also.
