I'd have to say no, not specifically fury, although I'm sure there are plenty of people in the furry fandom who are fans of that game/comic/show (whatever League of Legends is) and would like those pins. Furry characters are anthropomorphic, which means animals with some human-like traits. The characters in those pins (mainly the one on the left) are zoomorphic, which means humans with some animal-like traits such as the pointed ears. Now, I do see zoomorphic characters in furry art now and then, so there is a bit of a crossover between the two characters styles within the furry fandom.
