300 Heroes proves, as CrusaderCast puts it so well in this video, "there is no Mandarin word for copyright", because it doesn't just copy League of Legends (literally, it re-uses LoL's textures), it makes use of as many famous characters from properties it didn't pay for as it can get its hands on.

There seems to be a healthy mix of Western and anime characters in the game, with a donkey-hurling Zorro Shrek easily my favourite.
The game's available to download only in China, surprise surprise, but if you want to give it a shot you can try downloading it from here.
You can see a more gameplay-focused clip below.
