Who voiced Flash the sloth in Zootopia?

Raymond S. Persi voiced Flash the sloth in Zootopia. Flash Slothmore is the famously slow-moving employee at the Department of Mammal Vehicles, where Judy Hopps and Nick Wilde visit him while investigating their case.

Persi was not simply an outside celebrity hired for a one-line joke. He was an animator, storyboard artist, director, writer, and voice actor who worked at Walt Disney Animation Studios. His animation background helped him perform Flash’s deliberately measured timing and understated comic delivery.

Persi also voiced Officer Higgins in Zootopia and had previously provided the voice of Gene in Wreck-It Ralph. He continued contributing to Disney animation through additional voices and story work, making Flash part of a broader career in animated filmmaking.

The character is often confused with other members of the cast because Nate Torrence voices Clawhauser, Tommy Chong voices Yax, and John Ratzenberger voices a different supporting character. Flash’s slow speech is the character’s gag; it is not evidence that another actor voiced him.
