Pro-Hong Kong Mei - Zenyatta

It helps that Zenyatta poses already look like a template for Expanding Brain memes with hardly any edits.

Let's focus on one thing at a time. Mei's gotten a pretty great traction going, so we'll be better off capitalizing on that.

If Mei is actually banned and the whole "meme each Overwatch character in turn to get them all banned" -ploy pulls through, we can go with Zenyatta for the second choice.
