* Extremely Serious But Chill: He is heavily dedicated to his undercover work and taking out anomalies, but maintains a surprisingly relaxed, "chill" demeanor around regular coworkers when off-duty. * Deeply Paranoid: Due to his ties to the government and the mysterious Animal Corporation, he is consistently suspicious of his surroundings. He actively distrusts Dr. Harlow and suspects the hospital is running dark, inhumane experiments. * Incredibly Insecure About Being Called "Silly": Despite being an anthropomorphic black cat in a sharp vest, the community emphasizes that he absolutely hates being referred to as a "silly guy" or a pet, taking himself very seriously. * Feral Instincts: Fans frequently write that despite his suave, professional suit-and-tie exterior, he will break character and straight-up hiss like a regular cat if startled, stressed, or cornered by an anomaly. * Composed Co-Worker (The "SecretIntern" Ship): Because the Secret Agent and the Intern both possess unusually high base sanity and enigmatic designs, the community frequently pairs them up. In these fanon interactions, the Agent acts as an emotionless, grounded straight-man to the Intern's bizarre, wide-smiling, anomalous behavior.
