Dr. Germahn[1] is a "stereotypical German scientist" who pops in to provide "scientific" explanations. As the amount of suggestive gags involving the main cast has decreased, the crew of Germahn Labs has been picking up some of the slack. Dr. Germahn is a bit of a pervert, and likes to use Amanda for his various experiments, predominantly shrinking.
Note that while Germahn Labs cast is appearing more often, Dr. Germahn himself doesn't. He is still around, but he doesn't need to be physically present all the time, using high definition cameras instead.[2]
It's implied that he developed the radio watches Tedd, Grace, Nanase and Ellen were using when infiltrating the Nest.[3]
It seems he be working with Arthur.[4] It's not clear if he was always part of DGB or if their cooperation is result of some changes made necessary by Magic Change, however it seem clear he emigrated from Germany to US.
