I have no doubt that sooner or later someone in Germany will start doing super hero comics. Well, D-Gruppe's origins goes back 4 decades now. THAT is scary (to me).
But if you speak German go check out You Tube and Nerdzig TV or even go over to Tales From The Kryptonian -Nerdzig is in German but Subzero posts in English.
