Agent X20

Agent X20 is a spy character from the British comic strip adaptation of the Gerry Anderson TV series Stingray, serving as a surface agent for the villainous Titan and working against the World Aquanaut Security Patrol led by Troy Tempest.

Few characters carry the cool mystique of a Silver Age spy quite like Agent X20, who first surfaced in the landmark debut issue of TV Century 21 back in 1965, brought to life by Alan Fennell and Eric Eden. Born from that golden moment when British comics were riding a wave of stylish, futuristic adventure, X20 kept dangerous company — sharing pages with the likes of Troy Tempest, Titan, and Commander Sam Shore across the pages of TV Century 21, Action 21, and Countdown. What's remarkable is the staying power: a run stretching from 1965 all the way to 1992 speaks to a character who clearly left a mark on readers who grew up with those iconic British weeklies. For collectors with a taste for Silver Age espionage flavour and the distinctive world of Century 21 Publications, Agent X20 is a genuine piece of comics history worth tracking down.
