Thelma Three

A creature of the early Bronze Age, Thelma Three made her entrance in the very first issue of Countdown back in 1971, brought to life by the creative team of Dennis Hooper and John M. Burns for Polystyle Publications. That debut alongside names like Captain Scarlet, Captain Blue, and Jeff Tracy places her in genuinely exciting company — the kind of action-packed, science-fiction-flavored world that made Countdown such a distinctive corner of British comics. With only a handful of catalogued appearances, she's a rare find, the sort of character that rewards the dedicated back-issue hunter who loves uncovering the hidden gems of early-seventies adventure comics.
