Dr. Barbara Morse

A S.H.I.E.L.D. biologist and scientist, Barbara Morse was dispatched to the Savage Land, where she crossed paths with the jungle lord Ka-Zar and his saber-tooth companion Zabu while investigating threats in that prehistoric wilderness — an early chapter before she later became the costumed agent Mockingbird.

Debuting in the pages of Astonishing Tales #12 in 1972, Dr. Barbara Morse is a Bronze Age Marvel creation brought to life by an impressive quartet of talents — Roy Thomas, Len Wein, John Buscema, and Neal Adams. Her early adventures place her in vivid, wild company: the jungle lord Ka-Zar, the savage saber-tooth Zabu, and fellow scientists like Dr. Wilma Calvin and Dr. Paul Allen among her page-mates. With a key-issue debut to her name and appearances spanning Astonishing Tales and Planet of the Apes, she's a compact but genuinely collectible corner of early-'70s Marvel history worth tracking down.
