Spin first appeared in Flash volume 2 #238 published by DC Comics created by Tom Peyer and Freddie Williams II. Spin, Mr. Auerbach, kept a young man who is able to sense fears in others and making them a reality, in the basement of his news station. In the comic book, he has TV head for his costume.
In this Flash show, Spin will be portrayed by a female, Kiana Madiera who is famous for her role in Sacred Lies. Her name on the show will be Spencer Young. Her abilities and costume obviously will be different than the comic book version.
