Blizzard has released a series of comics delving into the backstories of the characters in the game. Feel free to play spot the difference with which comics got released in various locales:
America: https://playoverwatch.com/en-us/media/#comics-section
Russia: https://playoverwatch.com/ru-ru/media#comics-section
China: https://ow.blizzard.cn/media/ (there's some weird javascript stuff that prevents me from linking directly, click the speech bubble on the right side of the page to see the list of comics)
Taiwan: https://playoverwatch.com/zh-tw/media#comics-section
Edit: The tl;dr is that one of the comics doesn't exist in Russia or mainland China. Funnily enough, it looks like their CDN actually has a zh-cn version of the missing comic which is distinct from the zh-tw one (I don't know much about the chinese language but I'm assuming it's Simplified vs Traditional characters? Some of the onomatopoeia are translated differently too) https://static.playoverwatch.com/media/comics/10/zh-cn/comic...
