A young Enterprise crewman who vanishes on Scalos after tasting the local water, is accelerated into the Scalosians' time frame and dies of rapid ageing after being injured.
Compton is a member of the Enterprise landing party in the third-season Original Series episode Wink of an Eye, played by Geoffrey Binney.
The party beams down to a seemingly empty city on Scalos in answer to a distress call. Compton samples water from a fountain and disappears before McCoy's eyes. He has been accelerated to the speed at which the Scalosians live, so fast that they are invisible, and one of the Scalosian women takes him as a partner.
When Kirk is accelerated in turn, he finds Compton aboard the Enterprise, now docile and standing guard over the Scalosians' device. Compton nonetheless tries to help his captain and is struck in the scuffle. Newly accelerated people cannot survive cell damage, and he ages and dies within moments.
