Oh and the Monkey is probably supposed to be Herman Von Klemp(the head in the jar)'s robot monkey,Brutus . Hellboy first defated von klempt and the monkey by shoving von klempt inthe Brutus' mouth. Von Klempt is one of Kroenen's best friends, they went to school together. Also, Kroenen killed Zinco in an argument, just because Klempt soke about Rasputin rongly. It would be cool to have Zinco in the next movie, as He's got a MAHUSIVE robot body he gets in and stuff. Plus, if you ead Wake the devil closely, all of Hellboy's stuff hasgot Zico on it, like acompany, and at the end, Zinco is wearing it too. It's confusing, bad guy company..... Go figure
Edit: Correction: Zinco isn't in a big robot suit, Leopold Kurtz is. And Kroenen kills Kurtz, and blinds Zinco, who stumbles and accidentally lands on the conveniently placed self-destruct button in the castle, destroying it. Luckily, Most of them survive.
