Fresno State, known officially as California State University, Fresno, transitioned to a costumed mascot to enhance the fan experience and foster greater engagement during athletic events and other campus activities. The shift from live mascots to costumed ones is a trend that many universities have adopted to ensure safety, accessibility, and a broader appeal to audiences of all ages.

Historically, Fresno State's live mascot was Victor E. Bulldog. However, in 1979, the university introduced a costumed version of Victor E. Bulldog to increase interaction with fans and community members. Costumed mascots can perform more animated actions and participate in a variety of promotional and community events that a live animal could not.
