Jay Garrick is a speedster from the past, a co-founder of the Justice Society of America and the original Flash. He is friends with Doctor Fate, the original Black Canary Dinah Drake, the original Blue Beetle Dan Garret, Al Pratt (the first individual to use the codename “The Atom”), Ted Grant (AKA Wildcat) and original Green Lantern Alan Scott. His successor Barry Allen looks up to him as an inspirational figure and mentor. It is stated that Dinah trusts him a lot as a friend of her mother's. In spite of some flirtatious comments by others, it is clear that Jay remains loyal to his wife, Joan Williams, and that he is somewhat out of touch with modern human behavior, and as such is considered by others to have an old fashioned way of thinking.
