Principal Diknoz

Principal Diknoz is the principal of the school Leopold Slikk studies at in Angry German Kid parodies. As such, Inside Out parodies, whose school environment lacks a distinct principal figure (due to school only featuring in one scene and being limited to the classroom Riley Andersen and her teacher and classmates are in), also feature Diknoz as the principal of said school.

In AGK parodies
In the original form, the Crazy AGK Assistant video appears to be a word-for-word parody of the original Angry German Kid video. However, unlike Leopold, the Assistant calmly interacts with his computer and voices his demands, and shows various non-violent verbal and motor tics.

While the name and the role of the character portrayed by the Assistant is not universally agreed upon, AngryGermanKid82, one of the most popular early parodists of AGK, gave him the name "Principal Diknoz" and the role of being the principal of Leopold's school. In this role, he calmly lists the various wrongdoings that Leopold has done, before, despite the latter's begging, giving him a punishment in the academic system and informing Leopold's parents. Other parodists may portray the Assistant as a teacher instead; for example, in CreativityTheEmotion's own Er Ist Wieder Da - #3: First Day of School, he has been assigned to work individually with Leopold, but is inevitably forced to send him to the principal's office, as a teacher typically would.

Diknoz and other school staff are often made fun of for their names in-universe; for example, "Diknoz" itself can be pronounced as "dick nose".

In Inside Out parodies
In the Inside Out Kid Series, Diknoz is briefly featured with not much difference from his role in AGK parodies. He briefly comments on Leopold's wrongdoings on his first day at a new school; however, due to Leopold being new to the school, Diknoz lets Leopold out without much thought or giving a particular punishment. Of note, however, is the fact that Diknoz, unlike his counterpart in AGK parodies, appears to be unaware of kids misbehaving as violently as Leopold.
