Is the entity in Knebel the same one from Mann gegen Mann?
Not only do they look similar in appearance, but the vocal performance in both songs is similar, even more so than compared with other Rammstein/ Lindemann songs.
I've not analyzed the videos or lyrics that deeply. Till explores a lot of similar themes in all his texts, but you can see how oppressing something already monstrous in Mann gegen Mann can lead to Knebel.
Just something I noticed now, lol.
