Rex Dexter of Mars

Rex Dexter of Mars is a Golden Age sci-fi comic hero created by Dick Briefer, first appearing in Mystery Men Comics #1 (1939). Born on Mars after Earth's scientists colonized the planet, Rex returns to Earth as an adult but soon embarks on thrilling space adventures with his companion, Cynde. The series, heavily influenced by Flash Gordon and Buck Rogers, featured futuristic technology, intergalactic battles, and alien encounters. Though it only lasted a few years, it remains a fascinating relic of early sci-fi comics.
