Proteus' Secretary is the personal assistant of Proteus.
When Proteus manifested in Midtown Manhattan, an office named Proteus Unlimited was established on the 13th floor of the Erie. The secretary manned the front desk.
Janine Melnitz and Slimer found the 13th floor and approached the secretary. She insisted they could only see Proteus if they had an appointment. Janine ignored her and shot the office doors open. The secretary abandoned the front desk and ran away.
