SEASON 1
>Barry uses his forensic abilities to determine his enemies’ weaknesses and defeat them. Changed so the rest of the team could have a more active role in the missions.
>Iris is a psychology student interning at CCPD as a junior criminal profiler. Changed to be closer to the comics.
>Eddie is a douchebag hotshot who dislikes Barry. He transferred to Central City after accidentally killing his partner and covering it up to protect his career. Changed as they thought making Barry’s rival a nice guy was a more interesting take.
>Caitlin is older, had a past relationship with Harrison Wells, and her not-so-dead boyfriend is Kyle Nimbus / The Mist. She was aged down to replace Hartley in the core trio, and her fiancé was changed into Ronnie Raymond / Firestorm to be closer to the comics.
>Hartley is part of the team, has a friendly rivalry with Cisco and is initially more concerned with salvaging his career than protecting the scene. Changed to streamline the cast. Caitlin took over his role.
>Joe is killed by the Mist in the pilot episode. Changed because Jesse L. Martin was just too awesome to waste.
>Snart and Rory are meta-humans. Changed to be closer to the comics.
>Dr. Light would be featured as a meta-human former S.T.AR. Labs scientist seeking revenge against Wells. Hartley likely took over his role.
>Barry and Caitlin would hook up. Changed after Grant Gustin suggested they sped up the Barry/Iris relationship.
