Bobbi Morse

Born in San Diego, California, Barbara Morse excelled at gymnastics and science. She won championships in gymnastics when she was a teenager before moving onto the challenge of university. Bobbi, as she preferred to be called, graduated from the Georgia Institute of Technology with a Ph.D. in biology. Intrigued as to what her favourite biology professor, Dr. Wilma Calvin, would be working on, she took her Civil Service examination so she could work on the government-sponsored project to rediscover the Super-Soldier formula that created Captain America (codenamed Project: Gladiator).

While working on the project she came to the attention of SHIELD and was invited to undertake training. With her previous background in gymnastics, she excelled at both the physical regimen and arts of espionage taught to all field agents. Her codename was issued as Agent 19, and her first mission was to go to the Savage Land to locate Ka-Zar.

Later on, working under codename Mockingbird she met Clint Barton who was working for Cross Technological Enterprises as security chief. Morse and Barton eloped together after defeating the villain Crossfire to the Pocono Mountains and married.

Morse moved into the Avengers Mansion with Barton when he returned to active duty and was introduced to the team as his wife, Mockingbird. The two of them moved to Los Angeles when Vision proposed they form a West Coast Avengers team. Later events caused strain between the happy couple and a divorce was set into motion.

In a much later issue, Mockingbird made a brief appearance as she attended a West Coast Avengers meeting to stand for election to return to the team. She was voted in as an "alternate member", otherwise known as a reserve member. She then returned to Detroit.

Later, Hawkeye, Mockingbird, and the other West Coast Avengers teamed up for a mission during which Ultron managed to abduct Mockingbird and used her thought patterns and personality to create his second robotic 'wife' Alkhema.

Turned out, however, that the Mockingbird that Ultron had taken was, in fact, a Skrull. The real Barbara Morse was abducted by the Skrulls shortly before Ultron grabbed her.
