Chaotic evil, loves violence and war. You will have to be comfortable with saying VERY offensive things, but it will be clear that it is satire. German Empire and Austria-Hungary's child.

Ideally, he has an annoying voice. If you want to try to do a German accent that's okay, but please also record yourself saying the lines without the accent. Voice can be relatively gender-neutral. 

Will come back as an adult (lead) in season 2.
