AfD-chan is a young caucasian woman with shoulderlength blue hair kept partially free and partially in a sidetail (on top of wearing a red hairpin in the form of the AfD's logo arrow) and greyish blue eyes with round glasses. She wears a white buttoned shirt with a red tie, a light grey skirt, and white socks. Her shoes can vary in style and colour, but are most commonly depicted as black Mary Janes. She's sometimes also depicted wearing no shoes, going around in just her socks.
Unlike Putsch-chan, AfD-chan has not yet completely given up on democracy, and attempts to change the system from within by participating in politics and elections. Which is not to say she disagrees with Putsch-chan's views, she just has a different, less direct or violent way of going about it. She can also be fairly sassy toward her ideological opponents.
Putsch-chan was created sometime in 2016 by /pol/'s German contingent. Like her name and looks imply, she was created to be a personification of the German alt-right political party Alternative für Deutschland, as a means of creating and disseminating propaganda to earn them votes. To that end, she's seen with a German flag in many pictures, and she's also been shown hanging out on occasion with "Deutscher Michel", a much older figure who represented German nationalism back in the 19th century. The latter had always been depicted with a nightcap, which contemporary AfD-chan art reinterprets as meaning German nationalism needs to wake up already.
