Ozpin alludes to the Wizard of Oz, from the novel of the same name. This allusion has had the following influences on the character and show:
- The initials of the Wizard's name, Oscar Zoroaster Phadrig Isaac Norman Henkel Emmannuel Ambroise Diggs, spell OZPINHEAD, which may be the origin of Ozpin's name, as well as his position as headmaster of Beacon Academy.
- The Wizard lived in Emerald City, and Ozpin's green motif likely comes from this.
- In "Known by its Song", Raven Branwen states that "Old Man Oz has a great and terrible secret". This could allude to the Wizard's title, "Oz, The Great and Terrible."
- Ozpin has the ability to reincarnate into different people. In the original The Wizard of Oz book, the Wizard appeared to Dorothy and her friends in several different forms all claiming to be the same person.
- Ozpin being discovered to be lying about Salem's immortality and the true nature of the war with her may allude to how the Wizard was revealed to be a fraud to Dorothy and her friends.
Role For Another Character's AllusionEdit
Some characters stand in as a certain role for another character's allusion, separately from their own. Ozpin stands in as Odin for Raven's allusion to Huginn:
- Huginn, along with Muninn, is a raven to whom Odin gave the ability to speak. Huginn and Muninn both traveled the world to gather information and report back to Odin.
Ozpin's emblem is a gear within a larger gear. This emblem appears on two of Ozpin's possessions:
- A metal circle on the front of his desk.
- Above the elevators in his office in Beacon Academy.
In the original Volume 1 Opening storyboard, the pair of glasses Ozpin is wearing are differently shaped and larger than the ones he wears in his final design.
- Ozpin was originally going to be voiced by Monty Oum.
- In the original Volume 1 Opening storyboard, Ozpin is shown sitting in a chair with Glynda standing nearby. A glint on his glasses turns into a flash of light, which acts as a transition.
