That's because Sun Wukong from LoL and Sun Wukong from RWBY are both based on the same character, Sun Wukong the monkey king from the old classic Chinese story Journey to the West.

Son Goku of the Dragonball series is also based on Sun Wukong. Many, many, many monkey-tailed characters are based on him.
