Hazel "Hank" Murphy is the captain of Cecil Tunt's underwater laboratory and has missiles tipped with VX nerve gas. He was killed when he was crushed by an off-brand soda machine, "just like the gypsy woman said". The soda machine was branded "GOZ," a reference to Harry Goz who was the voice actor for Captain Murphy on Sealab 2021. His death is a reference to the Sealab 2021 episode "All That Jazz," in which Captain Murphy is trapped under a "Bebop Cola" machine.
Captain Murphy is a reference to a character of the same name in SeaLab 2020 and the parody reboot Sealab 2021.
The backdrop in Captain Murphy's station is the same backdrop used in Sealab 2021.
Captain Murphy attempts to fix his monitor by slamming a wrench on the control panel, another reference to Sealab 2021.
Murphy is shown to be generous, assisting Ray, Lana, Cyril, and Archer in surviving by holding the emergency hatch, not letting them save him, and giving them instructions on how they should leave the lab alive. He died however as a result.
He was killed after being crushed by a soda machine. An entire episode of Sealab 2021 is dedicated to Captain Murphy being trapped under one.
