Peter Cullen Played A Robotic Villain In This Beloved '80s Live-Action Sci-Fi Show
Peter Cullen voiced a sinister robotic automobile on a beloved 1980s sci-fi series, years before becoming synonymous with Optimus Prime in Transformers.
Peter Cullen, a renowned voice actor who passed away on August 26, 2026, is best remembered for his role as Optimus Prime in the Transformers franchise. However, K.A.R.R., a robotic villain from Knight Rider, was not Cullen's only automotive role. K.A.R.R., short for Knight Automated Roving Robot, was a prototype designed to prioritize its own survival over protecting its driver.
Unleashed by thieves in Season 1, Episode 9, "Trust Doesn't Rust," K.A.R.R. ultimately met its demise after a game of chicken with Michael and K.I.T.T. in the same episode. Despite Cullen not reprise the role in subsequent seasons, he returned in 2009 for the NBC reboot of Knight Rider, voicing K.A.R.R., which could now transform into a humanoid robot.
Notably, both Knight Rider and Transformers shared connections, even if they never had an official crossover. Hasbro released a special Transformers figure, Agent Knight, in 2024, allowing fans to collect a toy that transformed from a Pontiac Firebird Trans Am into a robot, echoing the shared automotive theme.
