"Candace's Id" is the Id located inside the mind of Candace Flynn, which is, for some reason, represented as a grotesque monster.
The monster resembles Candace Flynn to some extent. It wears the same skirt, shirt and sports the same orange hair, but it goes barefoot and it has grey skin. It also looks more grotesque than Candace.
Being a part of Candace's mind, the monster protects it from any unwanted thoughts, even if this includes the gang, Fireside Girls and Jeremy Johnson. While doing this, the monster shows a hostile personality.
It has a soft spot, however, since it somehow got into a relationship with Buford Van Stomm when he remained behind.
Despite being a part of her mind, the Id failed to recognize Candace as herself, attacking her like the rest of the gang.
As stated above, the monster got into a short-lived relationship with the bully himself after he somehow remained behind in Candace's mind. The two seem to get along pretty well, but Buford soon left.
