One of the founding members of the Street Knights, Johnny Redwood was a young detective who worked closely with the police. But on a case, he was witness to a corrupt cop attempting to rape a victim. He intervened, but was later declared to be unfit for the case, and was removed from it. Leaving his job with the police in disgust, he sought an alternate career as a simple car mechanic. He built, as mostly a pet project, a flight suit that could use the biomass technology developed by his brilliant neighbor, Dr. Pardon, as fuel. This he and Dr. Pardon wanted to sell, but when the doctor was murdered, he decided to use it for himself in his investigation to find the murderer. Even with the case solved, he realized he had found his calling, and became the vigilante Homingbird, the flying detective.
