Original Ultraverse

Felicia Campbell was a medical doctor married to Bob Campbell, a former Army ranger turned Hollywood stuntman. The two of them were headhunted by the UltraTech corporation. Felicia joined their medical staff working on genetic engineering and developing Ultra enhancements, while Bob became the company's mascot and corporate hero, Prototype. The sleazy CEO Stanley Leland manipulated the couple in an attempt to sleep with Felicia, scheduling Bob's appearances to keep them apart and make him look like an absentee husband.

When UltraTech decided to recruit an actual Ultra for their mascot, Prototype 1.0 became obsolete. Leland arranged an accident where Bob lost an arm and was fired. Felicia and Bob's marriage fell apart after that, and they separated before ultimately divorcing.

Later the Aladdin organization helped Bob t become the armored hero Ranger and he and Felicia reconnected. Felicia became friends with Prototype 2.0, Jimmy Ruiz, and helped him learn to control his Ultra powers which were being used to power the new suit. Felicia, Bob, and Jimmy went after Leland and UltraTech for toying with their lives, and the entire company ended up being sold off to corporate raider J.D. Hunt.
