Are you a bad enough summoner to rescue Wukong?
Wukong is literally in every MOBA.
The monkey trickster warrior is a old Chinese archetype. It's no more usual to have it repeated than a raging barbarian with a big sword or a fallen angel or a blind fighting monk. Riot has done pretty well recently to have enough creativity / numerous enough influences on new champs that we see less familiar character types, but especially early in the game this wasn't usual. Nor bad, for that matter. People like playing as well-known archetypes. That's fun, and needn't be avoided for the sake of excessive novelty.
When the give a monkey twin Magnums and a jetpack with a cool hat I'll be happy.
