Black Claw

Schwarzkralle, also known as Black Claw, are organisation of Wesens who seek to take over the world and subjugate the Kehrseite ("normal" humans).

They served as the main antagonist-faction in Season 5 of NBC's Grimm, and also appeared in Season 6 in a minor role.

Operations
Black Claw operations rose a lot around 2015 and 2016, worldwide, but especially in Portland, where founders Bonaparte and Kleinager resided.

The group managed to kill most of the Wesen-council and kill many Wesens and Kehrseite alike.

By late 2016 Nick Burkhardt and Hadrian's Wall managed to eliminate the group's leaders and most, if not all cells.
