- professor Venomous: The two share an atypical villain-minion relationship with each other, as Venomous, although still referring to her as his minion, treats her more like a daughter. Fink does not seem him as a father figure (she is even implied to have a crush on him), but she still cares deeply about him, to the point that she would sacrifice herself, in order to protect him.
- Trina: They can sometimes be seen together, accompanying their respective father figures. Although not very close, they seem to get along.
- Black hat: She is one of Black hat's pupils, and similarly to her classmates, she admires him and enjoys being his pupil. Even though, she is not one of Black hat's preferred pupils, he still likes her violent and destructive behavior.
