Flash (Barry Allen)
His alter ego is "James Jesse". He was a circus acrobat who decided to become a criminal just like his "reverse namesake" Jesse James. He created shoes that allowed him to walk on air to first help him in the trapeze shows his family was in, as every member of his family was a trapeze expert and his father wanted him to be one also, and other dangerous gag gadgets for his crimes. He clashed with the Flash (Barry Allen) many times. In his first appearance, his Harlequin costume causes the Flash to guess he is in a circus, and he captures the Trickster after pogo-sticking to the trapeze.
