Background information

 * In the same episode, another "inner" is heard- Candace is heard arguing with her inner self. However, Inner Candace was never seen- it's possible that she looks like Inner Doof.
 * Also, in an earlier episode, Candace's subconscious was shown as an Id. It's possible that Inner Doof is Doofenshmirtz' Id, though he isn't as monstrous as Candace's Id.
