Katzenjammer's Links
As Rumple is aromantic and Katzenjammer is not, their relationship can be a bit strained at times. To combat this Katzenjammer often takes the role of aggressor and they end up seeming more like they hate each other. While in truth Katzenjammer would die for Rumple and Rumple is the same.
Rumple finds Katzenjammer to be amusing. They spar a lot and he sees him as a dear friend and someone he's in a relationship with. As they're both very aggressive dominant personalities this ends with a lot of sparring and jockeying for control.
Interrobang is one of Rumple's favorites so Katzenjammer sees him as someone he should protect. He is viciously protective of the slightly younger cyborg.
Interrobang finds Katzenjammer to be slightly intimidating but he respects his athority in the group and looks to him for protection and guidance when the need arises
