SInce everything from Ice king's past has a meaning to why he is the way he is now, i want to know who gunther was to him. I'll explain.


 * He kidnaps princesses because he used to call his fiance Betty his princess.


 * He imitates Marceline because they shared a past together

so it brings me to my question who is Gunther...and how important was he that Ice King now calls all the penguins Gunther. Anybody got any theories?
