Grimm Wehrmacht

"Blast it! A new type of Wehrmacht is made to destroy Beacon Academy! Now they're gonna destroy my village as soon as possible! Now I can't let this happen if this type of crap would happen! I better stop these new types of Wehrmacht bastards once and for all before they would ruin everything else."

--Su Ji-Hoon, Operation: Invasion Der Zukünftigen Akademie

The Grimm Wehrmacht is a Grimm faction of the Nazi Union. It is founded by Fegelein. During the Beacon War, and when there were some Nazi Union Beowolves, a type of sapient Beowolves, Fegelein uses his command to create their own types of Grimms by building a Grimm Machine.

Now if Grimm were tamed by the Nazi Union, and they used the Grimm Machine to create more types of Grimm monsters, then some Grimm monsters would become part of the Nazi Union because they are tamed and/or trained by Nazi Union.

They can have the Grimm Heer, and the Grimm Luftwaffe, but they haven't mastered their naval Grimm taming yet to have a Grimm Kriegsmarine.

Now in battle, they are better than regular Grimmmonsters  because they are smarter, use armors, use weapons, can have drivers, and use veil power.

Now they will fight for Fegelein, the normal Wehrmacht, the Nazi Union, and the Coalition of the Red Star, just when Nazi Union is their benefactors.
