Hendorff is the burly Starfleet security officer whom James Kirk mockingly calls Cupcake, seen in all three Kelvin timeline films from an Iowa bar brawl to service aboard the Enterprise.
Hendorff first appears in Star Trek (2009), played by Jason Matthew Smith. As a cadet he steps in when Kirk pesters Uhura in a bar in Riverside, Iowa, earns the nickname Cupcake and leads the beating that follows. Three years on he is a security officer on the Enterprise, pleased to haul Kirk off the bridge when Spock has him removed.
In Star Trek Into Darkness he is one of the two guards Kirk takes on the covert trip to Qo'noS, told to swap his red shirt for a trader's clothes.
He appears again in Star Trek Beyond, still with the crew. His surname is not spoken in the first film and comes from the later ones.
