Sorry I accidentally deleted my last post. I appreciate the answers the two people gave.
This is some big larva I found and the head looks centipede-ish but the body is short and fat with less legs.
I went through my images and found an old photo of a beetle that was on my screen door. Maybe it's a larva for one of these?
That is the larvae of a some member of the Scarabaeoidea family.
Being German the first thing that comes to mind is the Cockchafer (Maikäfer).
The friend you have there looks like it could be a member of that family so it's possible that's the larva form. (But I'm no beetle expert)
Hopefully the Cock Chafer doesn't get its name from its activity
Last night there was a post about this. According to the post, at the time of naming "cock" was a word referring to size and "chafer" is the type of bug.
I did not fact check this, but it is an explanation I find preferable to the alternative.
edit: The name "cockchafer" derives from the late-17th-century usage of "cock" (in the sense of expressing size or vigour) + "chafer" which simply means an insect of this type, referring to its propensity for gnawing and damaging plants.
Maybe this guy could actually be a girl? https://en.m.wikipedia.org/wiki/Lucanus_cervus the female looks somewhat close and the larva looks similar.
