OR, they could have made him Rival instead of Zoom, seeing how he got nothing similar with Zoom except for "dad was evil" part, but got the qualities of the rival.

To introduce Zoom, you'd first need to establish Hunter Zolomon as a positive character and friend, who's life is ruined by Barry before he decides to go Reverse. Heck, have Eobard Thawne appear and tell him that being another Reverse-Flash is his destiny, make him mess with Hunter's head.

In the end, what we've got is... an OC to give the Black Flash backstory, who shares his name with Zoom.
