Page Image: the machine-translation in the speech bubbles is quite obvious to native Chinese speakers. It's clear that they are meant to be 'Stop him!' and 'Kill him!', but it actually amounts to (Formally) 'Suspend/put a stop to him' and (Matter-of-factly, instead of as a command) 'Murder him'. In either case, they sound funny rather than intimidating.

I delete:

• Axis Powers Hetalia Fanon (specially fanart) sometimes depicts Chinese Girl Taiwan as a Dragon Lady during World War II.
  • Not exactly canon, though...
  • Well, if you look at who she grew up with, she would've had to learn something. And ALL the nation-tans can fight.

Natter is bad. And besides, from what we know of Taiwan, she's a Moe Genki Girl who serves as Annoying Younger Sibling to a degree. Hardly any "overt sexual and physical aggression, untrustworthiness, and mysteriousness".
