It has been confirmed that The Flash star Tom Cavanagh will be playing the part of Pariah in the upcoming Crisis on Infinite Earths crossover event — but who is he? This is a doubly fitting piece of casting considering Cavanagh’s key role in defining the Arrowverse and the history of the mysterious man from the original Crisis on Infinite Earths comics, whose arrival heralds disaster.
Cavanagh has been a linchpin of the Arrowverse since The Flash season 1. He was originally cast as STAR Labs founder Harrison Wells, who was responsible for building the malfunctioning particle accelerator that triggered the superpowers of many people, including Flash. However, it was revealed over the course of season 1 that the man mentoring Barry Allen in the use of his superspeed was truly Eobard Thawne – a scientist from the future, who had assumed Wells’ identity and likeness, and had transformed himself into Barry Allen’s equal opposite, the Reverse-Flash.
Cavanagh remained part of the cast of The Flash after season 1, continuing to play Eobard Thawne in Wells’ form, as well as different versions of Harrison Wells from different Earths. It seems that one more version of Harrison Wells is destined to become the Arrowverse’s version of Pariah.
First appearing in DC Comics’ Crisis On Infinite Earths #1 in April 1985, the man who became known as Pariah was once a scientist on his version of Earth. Pariah developed weather-control technology and cured all diseases. It was his final and greatest achievement, proving the existence of the multiverse and an anti-matter universe, which would prove to be his undoing. It will be interesting to see how closely the TV event follows the comics event, and with Tom Cavanagh in this key role.
