Gibson worked for 30 years as a Science Cop, but when his wife, Alice, was killed by a SNATCHER during the "Bio-roid Panic of '46," he joined the Junker Agency as a "runner."

He majored in Criminal Psychology in college and has a good understanding of the criminal mind. Also, his 30 years of experience as a detective and Science Cop make him an incredibly valuable Junker because he is able to explore avenues of investigation which require scientific knowledge.

He is a rather stern, quiet man with a love for antiques. He lives with his daughter, Katrina and their dog who is named after Gibson's late wife.
