The creation is imitated by DOTA, and tower pushing games have been around for a long time. Most of the hero materials are designed by the designers themselves, and some are collected from stories from various countries.
For example,
The nine-tailed demon fox Ahri
The idea of ????Ari comes from About the nine-tailed fox - a mythical creature widely spread in various countries in East Asia. Ahri's main designer is Ezreal, and Coronach also helped with the design. During development, the Nine-Tailed Demon Fox had many different names. Ezreal preferred the name Gumiho. (For more information about the origin of Kumiho, please refer to [Wikipedia]). A player found a vote on Ahri's name on Riot's official Korean website. There were six options in one ***: Danbi (savior) Nabi (butterfly) Ruri (dazzling) Ari (elegant) Chorong (dazzling) Dasom ( Cute) Ahri was released on all servers around the world on the day the Korean server was opened. The prototype of Ahri's dance is Ahri's passive, Essence Theft, from Girls' Generation's "Run Devil Run". The original name was Soul Eater. Because it overlapped with the name of Dogou's passive, A small patch after Ahri was officially released was changed to its current name. Ahri's final artwork had fox ears that were not present in the original artwork, and her costume also underwent some changes. Ahri is wearing Korean traditional clothing - Hanbok (Hanbok) in the Dynasty skin. And under that skin her dance changes into a traditional Korean folk dance.
There are also Chinese-style blind monks such as Xin Zhao.
