The Doctor

A Bronze Age arrival from Marvel UK, The Doctor made their comics debut in TV Action #102 in 1973 and has kept remarkable company over the decades — sharing pages with the likes of Marshal Law, The Sleepman, and Danny Mallon across titles including Strip and the Doctor Who Classics series. With a publishing presence stretching across roughly forty years, this is a character whose longevity speaks for itself, turning up in key collections well into the 2010s. Nine catalog appearances may seem modest, but for the dedicated Marvel UK enthusiast, each one is a genuine find worth tracking down.
